8. Yellow-bellied snake (Pelamis platurus)
LD50: 0.07
This is an aquatic snake, and although it is one of the most world widely spread aquatic species, including Indian (East African coast, Madagascar) and Pacific oceans (to the west coast of Americas), it is commonest in the coastal areas of Australia. It is a tiny and slender snake, with an average length of around 70 centimeters. Being named “yellow-bellied” , it’s obviously lightly colored on the ventral side (belly), and the ventral (back) side is black or dark brown.
