The sea snake is primarily found in the northern
waters of Australia. There are approximately 31 different
species of sea snake. All of them are dangerous to humans,
but relatively few of these bites cause any significant injury
because the sea snake fangs are extremely tiny, only 2-4 mm.
in length. They do contain neurotoxins, however, but most
often cannot penetrate the wetsuit worn by a diver. Deaths
that have been documented occurred among fishermen who ran
into their nests. Sea snakes bear their young on shore, and
spend the remainder of their lives in the ocean looking for
food, fish and eel. They are very shy and not aggressive by
After being bitten, side effects generally do not appear
for 20-30 minutes, at which point severe pain is experienced
in the affected limb. Droopy eyelids, respiratory weakness
and muscle pain can occur. There is anti-venom available for
sea snakes; however, if unavailable, the anti-venom for the
tiger snake may be used. An adult sea snake may carry enough
venom to kill approximately three adult people. Its primary
neurotoxin can cause peripheral paralysis. The sea snake venom
is approximately two times more potent than the land snake
venom, in comparing rattlesnakes, copperheads and water moccasins.
Although more lethal, there is less chances of being bitten
given the small size of the fangs and less aggressive nature
of the snake.
