Slender Sea Snake

The slender sea snake, also called the graceful small-headed sea snake, is a venomous sea snake of the Indian and Pacific Oceans. It eats eels. The head is small and the body long and slender towards the front. Total length averages 950 mm in males and 1,025 mm in females. Its range runs from the Persian Gulf to Pakistan, India, Sri Lanka and Bangladesh, and on through Southeast Asia to southern China, Queensland and Papua New Guinea (Wikipedia, general species account).

The venom is dangerous and can be fatal. Symptoms generally appear within 30 minutes of a bite, which is typically painless. The venom affects the muscles and causes paralysis, and victims may also have headache, thirst and sweating. No status is given for it in the Sri Lanka National Red List 2012 list checked.
