Yellow-lipped Sea Krait

The yellow-lipped sea krait, also called the banded sea krait, is a highly venomous snake found in tropical Indo-Pacific waters. It has distinctive black stripes, a yellow snout and a paddle-like tail for swimming, and the head is black with lateral nostrils. Females are much larger than males, averaging about 1.42 m against about 875 mm (Wikipedia, general species account).

It spends much of its time under water hunting eels and small fish with a very potent neurotoxic venom, but returns to land to digest, rest and reproduce. Females lay up to 10 eggs per clutch. Adult males are more active on land during mating and hunt in shallower water (Wikipedia, general species account).
