Young Brothers – Innovation and Opportunity

John Nelson Young had 5-kids – Edith, Herbert, William, John and Edgar; they hailed from San Diego.

In the summer of 1899, the four boys ran a glass-bottomed boat at Catalina Island; this was the beginning of the famous glass-bottom boat rides that continue today.

It marked the beginning of the innovation and opportunity that followed the brothers.

They took guests out fishing during the day; to help promote their activities they took hotel employees on moonlight sails. It’s not clear if this was the beginning of the booze cruise or pau hana parties.

They saw opportunity in Hawai‘i; in January 1900, Herbert (29) and William (25) arrived in Honolulu; in October of that year, their younger brother, John Alexander Young, arrived – they called him Jack (18).

They formed Young Brothers.

Their early years were focused around Honolulu Harbor. They would run lines for anchoring or docking vessels, carry supplies and sailors to ships at anchor outside the harbor, and various other harbor-related activities.

They built a glass bottom boat and started a sport fishing service – and would take pictures of the people with their fish. Some suggest this was the beginning of the charter boat business in Hawai‘i.

They expanded into shark fishing … Jack also saw another opportunity and a new sport was born – they took customers out to ‘hunt’ flying fish, with customers at the bow of their skiff with shot guns “taking pot shots at fish on the fly”.

Back then, there were two inter-island freight carriers, Inter-Island Steam Navigation and Wilder Steamship Company. In 1905 Inter-Island bought out Wilder. (Later Inter-Island became Hawaiian Airlines.)

Opportunity knocked again for Young Brothers.

Libby’s shut down its pineapple operation in windward O‘ahu and started planting pineapples on the west end of Molokai.

Libby’s built a wharf at Kolo, just below Maunaloa. Kolo had a shallow channel and the Inter-Island Steam Navigation ships couldn’t get in.

The brothers made a special tender and with its first barges, YB-1 and YB-2, Young Brothers got into the freight business, carrying pineapple from Kolo Wharf to Libby’s O‘ahu cannery.

With expanded freight service to Molokai (to Kolo and Kaunakakai,) Young Brothers further innovated with the practice of tandem towing – towing two barges with one tug.

They pioneered the system because two barges were needed to serve Molokai – they would drop one off at Kolo and then carry on to Kaunakakai; they’d pick up the Kolo barge on the way back to Honolulu.

(The 1946 tsunami destroyed Kolo Wharf. Rather than repair it, Libby’s bought trucks and shipped their pineapples out of Kaunakakai.)

Young Brothers’ innovation did not stop. In 1929, their new tug, the Mikimiki, was launched.

The excellent performance of the original Mikimiki led to the adoption of her basic design for a large fleet of tugs that the US Army Transport Service copied for World War II service.

Young Brothers continued with another innovation; the Kapena class tugs that modernizes the Young Brothers’ fleet. They are named for two prior captains; the first was named for Jack Young Sr and his oldest son Jack Young Jr. Both were instrumental in making Young Brothers a leader in inter-island shipping.

Jack Young had three children, Jack Jr, Babe and Kenny. Jack Sr had 11 grandchildren, but he and his wife had died knowing only one of them. Jack Sr is my grandfather, but I never knew him or my grandmother; Kenny is my father.

While the Youngs have been out of Young Brothers for a long time, we still feel very much a part of it and its heritage.

William Edward Young

John and Eleanor Young had a family of five children: Annie Edith Young was born December 28, 1868 (in San Francisco), then in San Diego, Herbert Gray Young, on March 21, 1870; William Edward Young, on April 24, 1875; John Alexander ‘Jack’ Young, on January 2 1882; and Edgar Nelson Young, on July 21, 1885.

John’s father was a chair and cabinetmaker, and John followed in his father’s footsteps. The family supplemented their income with produce from their garden; John often took the older boys fishing mackerel and bottom fish in San Diego Bay.

Eleanor Young developed rheumatoid arthritis when she was in her early forties. She died on February 16, 1894 at age forty-five, leaving minor children Jack, 12, and Edgar, 10, and granddaughter Belle, 8.

John Young suffered from tuberculosis in the 1890s. After Eleanor died, he traveled extensively trying in vain to find a more suitable climate. He finally returned to San Diego. There, he died September 13, 1896 at age fifty-seven.

John Young’s sons, Herb and Will had a business in the summers of 1898 and 1899 at Catalina Island (the Island was then owned by the Banning Brothers).

They set up a concession to provide sightseeing excursion boats circling the Island and fishing for the tourists. They also got permission to take tourists out in glass-bottomed boats to view the fish and undersea creatures. It was a very successful venture.

Will was a good storyteller and kept the tourists amused, while Herb went diving under the boat and excited the fish. Once he found a hammerhead shark with a lot of curiosity. Herb played with the shark and put on a good show for the viewers who thought he might be in mortal danger. The glass-bottomed boat trips became very popular.

Then Herb and Will saw opportunity for business in Honolulu. Herb thought it looked good and persuaded Will to join him there in December. In January 1900, Herb and Will started Young Brothers.

They purchased a small launch, the Billy, and made a business running lines for the ships, delivering foodstuffs to the crews, and ferrying passengers. They were joined in October by their younger brother, John Alexander ‘Jack’ Young, who was then eighteen years old.

From their first days in Honolulu, the Young brothers were fascinated by the big sharks that infested the waters just outside the harbor where the garbage was dumped.

While the three brothers were involved in their daily harbor activities, they came to befriend boat captains, passengers and interested bystanders who were fascinated by tales of sharks, and more particularly whether they attacked humans.

This led to a small side-business in shark hunting that quickly earned William the nickname ‘Sharkey Bill.’ Fishing parties would he formed from among hotel guests, who were taken out on the Billy for a day of shark fishing.

“[W]e got the contract for towing garbage out and dumping it daily. But despite the numbers of horses ashore, only once in a while was a carcass available for our uses.”

“We had our best opportunity to study the sharks as they fought over the floating body, literally going into frenzies with snapping jaws and lashing tails, whipping the water white with foam.” (William Young)

“Little by little we began to suspect that there might be profit in our old friend the shark. Passengers and visitors were very curious about the tigers of the sea and often became rabid partisans, as they do to this day, over the question of whether sharks attack and eat human beings.”

“What would have been rather gruesome stories, save for the fact that they were matched by many in our own daily experience, were recounted to make or discredit a point.”

“Our opinions were sought, but we could not say for sure, never having actually seen a shark devour a man. But we could and did offer to take anyone shark fishing who wanted to go, and many went.”

“Our method was always the same, except when circumstances beyond our control arose, to which we had to adapt our [shark] hunting …”

“It was great sport to take a small party of fishermen out, and using a carcass for bait, attract sharks close enough to catch or kill.”

“But it does not attack at once. A shark is above all cautious, for all his curiosity. He swims around the carcass, sniffing and sizing up the situation.”

“He comes close to the boat and sticks up one cold, expressionless eye, and winks at us in his ghostly way. Then, once more he returns to the alluring meal spread so invitingly before him. He cannot seem to make up his mind. Finally he disappears.”

“Gone? Wait a bit and see. In twenty minutes or half an hour he is back, this time with four or five of his friends whom he has informed of the free meal that he found. They circle about, hungrily. … What is the matter, don’t they want it? Have patience, this is their custom.”

On February 27, 1904, Herbert Young caught a monster gray shark off Ewa in the harbor. Measuring fourteen feet long, it was the largest shark ever seen there. When opened, the stomach contained the remains of three big pigs and a quantity of horse flesh.

The body of one of the pigs was nearly intact and had apparently been just gulped down whole. The shark could easily have swallowed a man.

It was put on display at the Navy wharf. Then it was skinned by Fish Inspector Berndt and, after preparation, the skin was sent off to the fish commission as an outstanding specimen of gray shark.

On another adventure, “Professor PM Stewart who occupies one of the chairs of language in Cambridge University, England, has had an experience during his visit to Honolulu that probably never came to him before. He went shark fishing.”

“On Friday he caught a shark. His wife who has attracted much attention in this city on account of being a very tall striking looking blonde with very ultra English appearance, accompanied him and to catch the first shark.”

“He hooked one shark yesterday morning and drew the shark close to the boat and then started to dispatch the sea wolf with a spade. The weapon was bent and then Professor Stewart took a hatchet to strike the monster. In his excitement the professor struck the line with the hatchet cutting the line and allowing the shark to escape.”

“Later in the day a second shark was caught near the bell buoy. This time the shark was dispatched without cutting the line and was towed in shore. The shark measured about 14 feet in length and was of the man eating variety.”

The boys “have hit on a new scheme for shark fishing. They are able now to take the sharks with a hook and line instead of harpooning them as was done formerly. Some very successful expeditious have been taken out by tile young men.” (Hawaiian Star, June 2, 1906)

Shark jaws would sell for $5 apiece and were prized as souvenirs for mounting and display by members of the party, while the fins were taken away to be made into soup by the many Chinese who frequented the wharves.

On March 19, 1904, the Waikiki Aquarium opened. “The land and the building at Waikiki were donated by prominent citizens, and the traction company had the job of maintenance.”

[William]I applied for the position of manager, having previously caught and tended many fish with Herb for the Aquarium at Catalina. My application was accepted, and so for a year I herded fish. I not only nursed, fed and attended to their wants, but also, with the help of a native fisherman, caught all the specimens exhibited in the building.”

“Many were caught within a stone-throw of the building wall. There were big ones, little ones, brilliantly colored tropical fish, squid, shark and surgeon fish, which carries the sheathed spine near his tail for a weapon.” (William Young) He also continued to help run Young Brothers until the demands of Young Brothers compelled him to return full time.

William decided to make a little extra money by harpooning a large shark to show at the County Fair, held in Honolulu each September.

The Elks Club was in charge of the amusement concession, so for a booth rental of $60, William set up a display of a shark packed in ice and charged ten cents a look. By the end of the week, he had collected $1,500.

Herbert sold his interest in the Young Brothers business and went to the mainland to look for work as a diver. Jack Young and Will Young incorporated the business in 1913 as Young Bros. Ltd; Will no longer took an active part in the business.

In the years that followed incorporation, it was necessary for the Young Brothers’ fleet to continue growing in order to meet the needs of business that paralleled the expanding territorial economy.

Will preferred to pursue his fascination with sharks and eventually left the islands for good in 1921 to become a well-known international shark hunter.

“A business proposition that looked promising came along about this time, but it meant that I would leave Honolulu for New York to be gone an indefinite time. Nothing of a business nature held me in Hawaii, and so I made arrangements to sail aboard the President Harrison.”

“I went aboard just as I had boarded all the big ships for so many years in the harbor, but this time there would be no hurried climb over the side to the towboat as the vessel swung out the channel. Once she had warped out of the dock, I was aboard for good, headed for the States and a new future.”

“Good-bye to Honolulu! A passenger at my elbow sighed and said, ‘I hate to go,’ which, I realized, summed up my case, but inadequately.”

William left Young Brothers in the hands of Jack, the last founding member of the company to remain in Hawai‘i. (Lots of information here is from William Young’s book Shark Shark, Young Brothers: 100 Years of Service, and a Young family background and genealogy.)

Young Brothers Come to Hawaii

John Nelson Young was born April 15, 1839 in St. Andrews, New Brunswick, the third child of John Alexander Young and Lucy Baldwin. John grew up in St. Andrews, a small but busy port on the shore of Passamaquoddy Bay, just across the international border from Maine.

His father was a chair and cabinetmaker, and John followed in his father’s footsteps. He also learned the art of trading and shipping for profit. In 1859, when he was twenty years old, he and his brothers, James and Alexander, left St. Andrews to go to California.

They sailed to Panama, crossed the Isthmus, and from there sailed up the west coast to San Francisco. John bought the schooner Champion and sailed between San Francisco and Sacramento carrying trade goods and passengers. (He may also have traded as far north as Portland, OR, or Eureka, CA, and as far south as San Diego.)

In San Francisco on April 15, 1868, John N. Young married Eleanor Annie Gray, daughter of Robert and Mary K Gray, emigrants from Robbinston, Maine. Shortly thereafter, John and Eleanor moved to San Diego.

In 1868, with his brothers James, Alexander, and William, John started a furniture business, one of the first commercial enterprises in San Diego. After James and Alex left the firm in 1869, John and William continued the firm of Young Brothers Carpenters and Furniture Builders, and added undertaking as a sideline.

William Young, John’s brother and business partner, died in 1873. John then reorganized the Young Brothers business as the Pioneer Furniture Company.

John and Eleanor had a growing family with five children. Annie Edith Young was born December 28, 1868 (in San Francisco), then in San Diego, Herbert Gray Young, on March 21, 1870; William Edward Young, on April 24, 1875; John Alexander ‘Jack’ Young, on January 2 1882; and Edgar Nelson Young, on July 21, 1885.

The family supplemented their income with produce from their garden John often took the older boys fishing mackerel and bottom fish in San Diego Bay.

John Young’s sons, Herbert and William, were working to help support the family. Herb learned deep sea diving by accepting several salvage jobs that required underwater skills and, in the summer of 1899, all four boys ran a glass-bottomed boat excursion at Catalina Island.

After the season ended, Herb landed a berth on a schooner bound for the Hawaiian Islands, and Will decided to join him on what he would later call ‘the great adventure.’ Twenty-nine-year-old Herb had served as chief engineer during the ten-day journey from San Francisco, while Will, then age twenty-five, served as crew.

The first view of Honolulu that greeted Will and Herb on January 19, 1900 and revealed a town numbering fewer than 45,000 residents. For several days, Chinatown had been burning to what would become a smoldering ruin in an effort to rid the city of bubonic plague.

With a capital of only $86, they bought a small launch, the Billie, and started running a ‘bum boat’ service in Honolulu harbor – they called their family business Young Brothers.

Jack Young arrived later that year (October); he once reminisced about arriving in Honolulu in 1900 with a few cans of fruit, a large trunk and only twenty-five cents in cash-too little to pay to have his trunk brought ashore. So, he rustled up a spare rowboat and rowed in his own gear.

In those days there were usually between five and twenty ships moored off Sand Island in the harbor at any one time. Most of ships used sail and needed help to move about in the crowded harbor.

The Young brothers ran lines for the ships in the harbor. When a ship came in, the anchor line had to be run out to secure the ship. Or if the ship needed to unload, a line had to be carried to the pier.

The next year they bought the Fun from the Metropolitan Meat Market and took over the contract to deliver meat and other fresh supplies to the ships anchored in the harbor. Herb got the contract, but Jack was assigned the job every morning of picking up meat, vegetables and fruits and deliver them to the various ships in the harbor.

Herb and Will also worked as a diving team, salvaging lost anchors, unfouling propellers, or inspecting hulls of ships for repairs. A more frequently needed undersea service was to scrape the sea growth off the hulls of ships.

The launches of the Young Brothers were routinely asked to pull stranded boats or ships off the shore or reef or to rescue ships in trouble at sea. In 1902 they saved six Japanese fishermen in a sampan that had become disabled in a sudden storm off Honolulu. The sampan had gone too far out to sea searching for fish and was caught by heavy seas.

The same year, they rescued a novice seaman in a rowboat who thought he could row out of the harbor to where a battleship was anchored. If he hadn’t been seen from the boathouse, he would have been lost. On another occasion, the schooner Mokihana was towed back to harbor from twenty miles out in 1901 when she lost control from the helm.

May 1903 saw the beginning of a long association between the Young Brothers and the Customs Department. Young Brothers purchased the launch Water Witch, from AA Young (no relation) and completely renovated her.

They entered a contract to use the Water Witch launch as a revenue and patrol boat, and to take boarding officers to all incoming liners. Herb had the privilege of presenting her and flying the Custom’s flag on May 21, 1903. The Water Witch remained in service for over forty years.

ln March of 1903, the Youngs moved from their first little boathouse on a sand spit near the lighthouse to a spot near what is now Piers 1&2. The Young Brothers’ boathouse was home to Herb, Will and Jack, and was a structure well known on the waterfront as a center of information for everything going on in the harbor.

In 1903, Edith moved to the Hawaiian Islands an joined her brothers. In 1905, Herb sold his interest in the Young Brothers business and went to the mainland to look for work as a diver. Young Brothers incorporated on May 5, 1913.

Following incorporation, Will stopped taking an active role in the operations of the company, preferring to pursue his fascination with sharks, and eventually left the islands for good in 1921 to become a well-known international shark hunter. Jack, the last founding member of the company to remain in Hawai‘i remained as the operating manager.

I am the youngest brother of the youngest brother of the youngest brother of Young Brothers. Jack Young is my grandfather. We never met him, and he and my grandmother never knew they had grandchildren from their son Kenny.

They both had died before they knew my mother was pregnant with my older brother. (Lots of information here is from Young Brothers: 100 Years of Service and a Young family background and genealogy.)

“Ah! What delicious-looking crabs you have here!”

So said the visitor to Ke Awa Lau o Puʻuloa – but he wasn’t speaking of crustaceans, he was speaking of the fishermen he saw as “fat crabs”, that is, a dainty morsel.

He was Mikololou, a man-eating shark from the Kaʻū district on the Island of Hawaiʻi.

He was part of a large company of sharks who came to visit from Hawaiʻi, Maui and Molokaʻi. Most of these had human relatives and were not desirous of eating human flesh, but among them were some who disregarded the relationship, and learned to like them.

The sharks had planned to make a circuit of the islands and perhaps later to visit Kahiki. They stopped at Puʻuloa (Pearl Harbor.)

Kaʻahupahau, hearing those words, knew at once that some of the strangers were man-eaters. Guardians of the area, she and her brother Kahiʻuka went into action to protect the fishermen.

But Kaʻahupahau could not distinguish between the good and the bad sharks; she then she changed into the form of a great net and hemmed in her visitors while the fishermen who answered her signal came to destroy them.

Her brother Kahiʻuka struck at intruders with his tail, one side of which was larger than the other; the fishermen hauled in the nets to shore and Mikololou was cast upon the shore with the evil doers, where they were left to die of the intense heat.

All but Mikololou were soon dead; though his body died his head lived on and as the fishermen passed to and from their work, his eyes followed them and tears rolled down his face. At last his tongue fell out. Some children playing nearby found it. They picked it up and cast it into the sea.

Now Mikololou’s spirit had passed out of his head into his tongue and as soon as he felt the water again he became a whole shark. With a triumphant flop of his tail, he headed for home to join his friends again. When Kaʻahupahau saw him, it was too late to prevent his departure.

“Mikololou lived through his tongue,” or, as the Hawaiians say, “I ola o Mikololou i ka alelo.” This saying implies that however much trouble one may have, there is always a way of escape.

Kaʻahupahau lived in an underwater cave in Honouliuli lagoon (West Loch.) Kahiʻuka lived in an underwater cave off Mokuʻumeʻume (Ford Island) near Keanapuaʻa Point at the entrance of East Loch

Kaʻahupahau may mean “Well-cared for Feather Cloak” (the feather cloak was a symbol of royalty). Kahiʻuka means “Smiting Tail”; his shark tail was used to strike at enemy sharks; he also used his tail to strike fishermen as a warning that unfriendly sharks had entered Puʻuloa.

Such guardian sharks, which inhabited the coastlines of all the islands, were benevolent gods who were cared for and worshiped by the people and who aided fishermen, protected the life of the seas, and drove off man-eating sharks.

Pukui notes Kaʻahupahau in ʻŌlelo Noʻeau: Hawaiian Proverbs and Poetical Sayings, No. 105: “Alahula o Puʻuloa, he alahele na Kaʻahupahau”: “Everywhere in Puʻuloa is the trail of Kaʻahupahau.”

“Said of a person who goes everywhere, looking, peering, seeing all, or of a person familiar with every nook and corner of a place.” Kaʻahupahau was noted for traveling about, vigilantly guarding her domain against man-eating invaders.

Puʻuloa also was home to Komoawa, (or Kamoawa,) a large shark who was Kaʻahupahau’s watcher. His cave, called Keaaliʻi, was at the entrance of Puʻuloa. (Thrum, Hawaii-edu) Kualiʻi guards the entrance to Pearl Harbor, while the home of Kaʻahupahau is deeper into Honouliuli lagoon.

Years later, the US Navy, having acquired Pearl Harbor, was working to expand the facilities. This included dredging the channel, adding a coal station and construction of a drydock.

“The dredging of the Pearl Harbor channel was begun long before the drydock was more than desultorily talked of – in 1900. It took many years to deepen, straighten and widen the channel into the lochs sufficiently for a man of war to enter.”

“But the work progressed steadily if slowly, and on December 14, 1911, the cruiser California steamed from Honolulu to the entrance to Pearl Harbor, and then, turning her gray nose inward, proceeded majestically through the still tortuous channel and dropped her anchor off the dry dock site.” (Hawaiian Gazette, November 24, 1916)

The drydock was to be the “Largest In (the) World – Less than a decade will have elapsed between the beginning of the great work and its completion.”

“And when the Pearl Harbor drydock is finished it will be the largest and the finest in the world, capable of accommodating any vessel now built or building, or that probably ever will be built by the United States.” (Hawaiian Gazette, November 24, 1916)

But, during construction, disaster occurred. “Much progress had at that time been made on the construction of the drydock, and success seemed assured. But the contractors had been having trouble with the bed of the drydock … it suddenly blew up with a tremendous explosion. No lives were lost, although there were several narrow escapes.”

“But the work of years had been wrecked … pressure had forced the bottom of the drydock up until it literally burst (on February 17, 1913.”) (Hawaiian Gazette, November 24, 1916)

“For a time it was feared that the entire project might have to be abandoned. But Uncle Sam’s engineers refused to be defeated by natural forces, and finally, after long experiment, mean were found for anchoring the bottom of the drydock.”

“Admiral Harris was one of the board that came to Hawaii to investigate the causes for the explosion and try to find a way of preventing future disasters of similar nature.” (Hawaiian Gazette, November 24, 1916)

They cannot say they were not forewarned. “While at work three Hawaiian fishermen come to where we were working, one of whom was aged, who asked me what we were doing there.

‘Digging a hole 50 feet deep’ was the reply. He then told me to move away from there; and when asked why, he said, ‘These places are tabu; they belong to shark god, name Kaʻahupahau.’” (Richards (a worker on the drydock project,) Navy-mil)

“The old man was watching my men working, and talking to them. Again he came over to me with tears in his eyes and asked me to quit digging ‘til my boss came. “I told him, I can’t do that.” They stayed there several hours, then he said to me that, ‘You people will be punished severely.’” (Richards, Navy-mil)

“Several years ago, some will remember, when work started on the Pearl Harbor naval dry dock, some of the Hawaiians said the location chosen would disturb a “shark god” who would be affronted and they prophesied dire disasters.”

“The work was started and there came a collapse. The forecasters of trouble were prophets. Changes were made in plans and locations.” (Maui News, June 9, 1922)

Merely a coincidence? Some think not.

One of the workers on the project noted, “As we went along pumping the water out of the dock, we pumped out five feet and cleaned the side and plastered and corked all the leak, 15 to 20 days and then pumped till we got to the bottom which was full of mud and in the middle of the dock where I went through a cave of nine feet diameter.”

“Mr. Hartman, assistant boss, found a backbone of a big shark, 14′ 4″ long. I came by where they were working when Mr. Hartman said to me, ‘You certainly got the shark. Here it is.’” (Richards, Navy-mil) (The Story of Mikololou is from Wiggins, Beckwith)

Manō Kihikihi

They are easy to identify … and their name tells you what to look for (their body and head shape resemble a hammer, when viewed from above (or below.))

Marine organisms generate an electric field around their body; some believe the shape of the hammerhead’s head allows electro-receptive organs in the animal to have increased sensory abilities – a beneficial quality when searching for prey.

In addition, the head shape may aid in their movements, providing lift or possibly a smaller turning radius.

Since sharks are ‘apex predators’ at the top of their food chain, they may influence the population structure of species lower in that food chain.

The sharks are found in warm and tropical waters, worldwide from 46° north to 36° south. They can be found down to depths of over 1,600 feet, but is most often found above 80-feet. During the day they are more often found close to shore and at night they hunt further offshore.

The scalloped hammerhead, one of the most commonly seen hammerhead sharks in Hawaiʻi, generally reaches between 5 to 10-feet in length – adults are usually found in the open ocean, often around seamounts or outer reef slopes.

Most fish hatch from eggs outside the females’ bodies, but hammerheads, as well as other sharks, are born alive – the shark babies are called ‘pups.’ As the pups grow, they spread out, forming schools that feed on the bottom at night. At maturity, the young sharks head offshore. (Scott)

Kāneʻohe Bay, Oahu, Hawaii, is a pupping and nursery ground for the scalloped hammerhead shark and hammerhead shark pups are the most abundant top-level predator in the bay. (Lowe)

Females travel to shallow, protected waters in the spring and summer months to give birth.

Between April and October, adult hammerhead sharks enter Kāneʻohe Bay, deliver 15 to 30-pups about 20-inches long, mate and then leave. (Scott)

It is estimated that as many as 5,000-10,000-shark pups are born in Kāneʻohe Bay each year and that the pups remain in the bay only 3-4 months after being born. They eat small fish and crustaceans.

Young hammerheads graze along the bay floors, mostly at night. As the youngsters grow, they gradually move to the mouths of the bay and eventually join their relatives in the deep water. (Scott)

Adults occur singly, in pairs, and in small schools while young scalloped hammerhead sharks live in large schools. It is thought that male and female scalloped hammerheads may segregate during certain times of their life history. (ufl-edu)

Hammerheads are among the majority of sharks whose attacks on people, if they happen at all, are defensive in nature. Almost all sharks will show an aggressive display if cornered, as will most animals. (pbs)

Though hammerheads are not usually aggressive, they should be considered potentially dangerous.
