Daily Critter Facts, Reefs, Reptile Facts, Snake Facts

The Dubois’ sea snake is a species of highly venomous sea snake found in New Caledonia, Papua New Guinea, and the northern, eastern, and western coastal regions of Australia. Even though they face the threats of habitat destruction at the hands of gas and oil drilling; overfishing; and climate change, which causes temperature extremes, these snakes are listed as Least Concern by the IUCN.

First the Stats…

Scientific name: Aipysurus duboisii
Weight: Up to 2.86 lbs.
Length: Up to 4.86 feet
Lifespan: Up to 15 years

Now on to the Facts!

1.) Their populations are unfortunately decreasing.

2.) They also go by the name reef shallows sea snake.

3.) These snakes can dive to depths of up to 262 feet.

4.) Various fish and moray eels are on the menu.

5.) The fangs of these snakes measure up to just .07 inch long.

But wait, there’s more on the Dubois’ sea snake!

6.) The venom yield is up to 1.52 ounces! The average venom yield of venomous snakes is just .008 ounce.

7.) Dubois’ snakes are crepuscular (active at dawn and dusk).

Did you know…?
Their venom is classified as a neurotoxin that can cause flaccid paralysis (severe muscle tone loss), droopy eyelids, difficulty swallowing, headache, sweating, vomiting, body aches, muscle stiffness, hyperkalemic cardiotoxicity, acute kidney failure, muscle necrosis, myoglobinuria, and elevated creatinine levels.

8.) The specific name, duboisii, is devoted to Belgian naturalist Charles Frédéric Dubois.

9.) Dubois’ sea snakes are viviparous (give live birth, rather than lay eggs).

10.) These critters are deemed the most venomous sea snake in the world and the 3rd most venomous snake, after the inland Taipan and the eastern brown snake. Both of which are also from Australia.

But wait, there’s still more on the Dubois’ sea snake!

11.) Females can birth 9 or more snakelets.

12.) Snakelets are born precocial (self sufficient) and fully venomous.

Now a Short Dubois’ Sea Snake Video!

This video talks about sea snakes in general.

With over 50 years of critter experience to my credit and hundreds of zoology teaching hours to people around the world, I have amassed not only a continuing thirst for critter knowledge but a desire to teach others all I can about the majesty and wonder of our natural world. Critter Science is a culmination of such knowledge. I have hands on as well as book acquired intel on all kinds of critters. Whether they're on land, sea, or in the air. I will never say that I know everything about all animals. That's impossible, even for a savant. But, that being said, ask me any animal question and I'll answer it. If I don't know the answer, I'll get an answer for you!
