Snake | Images of Old Hawaiʻi

Before humans came to the Islands, Hawai‛i was a bird paradise, lacking many of the types of animals found elsewhere in the world.

Due to the remote nature of these volcanic islands, organisms had to travel over 2,000 miles by wind or sea to reach these shores, and then survive and reproduce in a strange and sometimes harsh new environment.

The establishment of a species was a rare event, estimated to happen only once every 10,000-100,000 years.

Land-dwelling reptiles were among those excluded by the perilous journey (and their physiology) from starting new lives in Hawai‛i. The geckos and lizards that are common visitors to our windows and rock walls arrived with the assistance of humans.

Fortunately, their legless cousins (snakes) didn’t make the trip, and laws were eventually put into place to prevent the introduction of snakes, recognizing the threat to our native birds. (Big Island Invasive Species Council)

We repeatedly say, Hawai‘i doesn’t have snakes.

Then, Hawai‘i’s Department of Agriculture issued a news release stating, “A highly venomous yellow-bellied sea snake was found washed up on the shore at Honoli‘i Beach in Hilo”.

“While these sea snakes are rarely seen onshore in Hawai‘i, the Hawai‘i Department of Agriculture’s Plant Quarantine Branch (PQB) strongly advises beach and ocean goers not to touch the venomous sea snakes which are often mistaken for eels. A sea snake is easily distinguished by the bright yellow markings on its underside.”

The yellow-bellied sea snake is the most widespread snake species on earth. It is found throughout the Indian and Pacific Oceans and from the eastern coast of Africa to the western coast of Central America.

Unique among sea snakes, the yellow-bellied sea snake usually lives completely out at sea, criss-crossing the ocean by riding the ocean currents. While it is considered a pelagic (open ocean) species, it is occasionally carried into shallow water close to shore, or may even be beached during period of strong winds. (Waikiki Aquarium)

In the wild, the Yellow-bellied Sea Snake eats only fish. It hunts by stealthily approaching its prey or by waiting motionless at the surface and ambushing fish that come to shelter underneath it (small fish are often attracted to inanimate objects such as floating debris).

With its mouth agape the snake makes a rapid sideways swipe to snare any fish that comes too close. This snake can even ambush small fish behind its head by smoothly swimming backwards so that the prey then comes within range of its mouth. (Australian Museum)

“Sea snakes are distant relatives of cobras that have adapted to life in the ocean. These air-breathing marine reptiles can stay submerged for about two hours and can dive to about 300 feet.”

They catch their “prey with a sideways strike of the head. These predators quickly paralyze their prey by injecting a powerful venom through needlelike fangs. The snakes swallow their immobilized meal whole.”

“Unlike other species, they shun fresh and brackish water, and thus are not found in rivers or estuaries. Also, yellow-bellied sea snakes bear live young. Therefore, they don’t come ashore to lay eggs like other snakes.” (Susan Scott)

The yellow-bellied sea snake is reported to be among the more docile of sea snake species, but its venom is a potent nerve toxin that acts by blocking transmission of messages from nerves to muscles.

Apparently, however, sea snakes do not usually inject their toxin when biting defensively and two of three defensive bites involve no toxin. The greatest number of sea snake bites to humans are reported from the Philippines and southeastern Asia where snakes are accidentally caught in fishing nets.

Fatal bites result in death from respiratory, heart, or kidney failure. Less severe cases result in breakdown of muscle tissue and kidney damage, but victims recover without long-term effects if effective antivenom is received. (Waikiki Aquarium)

At least 52 species of sea snakes, all venomous, are found in the warm waters of the Pacific and Indian oceans. Of these, the yellow-bellied sea snake is the world’s most abundant and widespread, spanning the entire tropical and subtropical Pacific Ocean. (Susan Scott)

“Beaked sea snake venom, a species found in the South Pacific, is the most deadly of all: One drop can kill three adult men. The toxicity of yellow-bellied sea snake venom is about a quarter that of the beaked sea snake, meaning it is still potentially lethal.”

“Fortunately, no sea snake bites have ever been recorded in Hawai‘i. Worldwide, the incidence of bites is unclear since most bites occur in areas with little health care and no medical records. One Malaysian study showed that of 120 sea snake bites, over 50 percent occurred to fishermen sorting fish and handling nets.” (Susan Scott)

Every now and then, there are reports of individual snakes in the Islands. Most recent captures of snakes have been in residential or natural areas, far from ports and often at sizes indicating they escaped or were released after spending some time in captivity here.

A call from an alarmed Kea‘au homeowner in 2009 led to the discovery of a 6′ boa constrictor in a garage. In 2011, a 9′ boa constrictor was captured by hunters in Waipahu, O‛ahu, and in 2013 a pedestrian found a rainbow boa cruising through the streets of Chinatown.

A 4-foot ball python was captured on a coffee farm in Kā‘anapali, Maui, in 2016. In 2017, a jogger found the body of a 5′ boa near a nature preserve in Kauai, just months after a live 7′ boa was found in a Nu‛uanu driveway. (BIISC)

Non-venomous boas and pythons are two of the most popular kinds of pet snakes and are among the most common showing up in Hawai‘i. These animals are likely not accidental introductions but were intentionally smuggled or shipped to Hawai‘i in violation of state law.

While snakes can make great, low-maintenance pets for responsible pet owners in other places, the risk to Hawai‘i’s already threatened ecosystems is far too great to risk the chance of any snake species establishing in the wild. (BIISC)

To encourage misguided reptile enthusiasts to do the right thing, Hawai‘i has offered an ongoing amnesty program for anyone who turns in an illegal animal.

The no-questions-asked policy allows individuals to drop off any prohibited animal for free and without fear of punishment at any zoo, Humane Society, or HDOA office in the state. This is a good deal considering that importing or owning a snake can lead to up to 3 years of jail time and fines of $200,000. (BIISC)

“Any person convicted of owning, transporting, or possessing any snake or restricted (without a permit) or prohibited plant, animal, or microorganism may be:

fined up to $200,000;
imprisoned not more than three years; and
pay for all costs relating to the capture or eradication of the pest.” (Hawaii Department of Agriculture)

A headline in the April 11, 1902 issue of Kuokoa read, “Snakes are Allowed to be Imported to Hawaii.” The article went on to state,

“It was thoroughly believed that a person or persons could not bring in snakes from foreign lands into Hawaii, but the head custom inspector received a letter telling him that there is no law prohibiting the import of this type of animal into Hawaii, and should it be brought in by a person or persons, he has [no] right to prevent the bringing of it ashore.”

“It is right for us to oppose this with what power we have. There are many pests currently brought into Hawaii, and we do not want to bring in others. Before the arrival to Hawaii nei, there were no mosquitoes here, and they could be up at night without their hands tiring out from constantly waving them off.”

“That isn’t all, there is the mongoose that are eating chicks, and eggs, and we hear that a baby left somewhere by its mother while she was washing clothes, died because it was got by a mongoose which sucked all of its blood.”

“There are also mynah birds, fleas, and many, many other pests brought into Hawaii after the arrival of the enlightened races into Hawaii, and here is another thing that is wanted to be open to a person or persons to bring into Hawaii.”

“If these snakes come into Hawaii nei, and they spread in the forests, we will not be able to let our children go out to those places without facing calamity. Not just the children, but animals will be in danger of being bit by these snakes.”

“If the snakes are allowed, the time will perhaps come when lions and tigers will be imported, and we will be just like most of the lands of the world.”

“We want the beautiful things of the other lands, but the problems are what we don’t want. If they import beneficial things, we will happily take them let them free in our verdant fields of Hawaii nei for them to run about; however, if they are to bring in pests, we will stand and exterminate them when they step within the borders of this Territory.”

Things changed … on May 22, 1902, US Secretary of Agriculture James Wilson, sent statement titled, Importation Of Reptiles Into Hawaii. In it, he stated,

“Washington, DC, May 22, 1902. Under the provisions of section 1 of the act of Congress approved May 25, 1900, entitled ‘An Act to enlarge the powers of the Department of Agriculture, prohibit the transportation by interstate commerce of game killed in violation of local laws, and for other purposes,’ …

“… the Secretary of Agriculture is authorized to regulate the introduction of birds and animals in localities where they have not heretofore existed, and to make and publish all needful rules and regulations for carrying out the purposes of the act.”

“In accordance with the authority thus conferred, and for the purpose of preventing the introduction of noxious reptiles into the Territory of Hawaii, the order issued under date of September 13, 1900, extending the list of foreign animals and birds which may be imported without permits (Circular No. 30, Biological Survey) …”

“… is hereby amended so that on and after July 1, 1902, and until further notice, permits will be required for the entry of reptiles at all ports of the Hawaiian Islands.”

“Such permits will be issued by the special inspector of this Department in Honolulu in the same form and subject to the same regulations as those now issued for mammals and birds.”

“But no permits will be issued for the entry of poisonous snakes of any kind. All applications for permits to import reptiles into Hawaii should be addressed to the special inspector of foreign animals and birds, Bishop Museum, Honolulu, H. I.”

“Under the regulations prescribed by the Secretary of the Treasury, under date of June 28, 1900 (Circular No. 101, division of customs), persons who have not already secured permits will be allowed a reasonable time in which to secure them after the arrival of the shipment at the port of entry.”

“In case the application for entry is not granted, or the required permit is not obtained in due time, the reptiles will be immediately exported or destroyed at the expense of the owner or agent. James Wilson, Secretary.”

That order was later amended by Secretary Wilson on June 19, 1905; it stated, “for the purpose of preventing the introduction of snakes into the Territory of Hawaii, the order issued under date of May 22, 1902 (Circular 36, Biological Survey), is hereby amended so that on and after August 1, 1905, and until further notice, no permits shall be issued for the entry of snakes of any kind at any port of the Hawaiian Islands.”

Hawai‘i Revised Statutes (§150A-6 Soil, plants, animals, etc., importation or possession prohibited) state, “No person shall transport, receive for transport, or cause to be transported to the State, for the purpose of debarkation or entry thereinto, any of the following: (3) Any live snake”.

That law goes on to state, “notwithstanding the list of animals prohibited entry into the State, the department [of Agriculture] may bring into and maintain in the State four live, sterile brown tree snakes of the male sex for the purpose of research or training of snake detector dogs …”

“… and further, that a government agency may bring into and maintain in the State not more than two live, nonvenomous snakes of the male sex solely for the purpose of exhibition in a government zoo”. (HRS §150A-6)
