Sea snakes, like the Banded Sea Krait or Laticauda Saint-Gironsi, mainly hunt small fish or conger and moray eels that they find in the corals where they hide. They hunt night and day and sometimes associate with jacks which cut down preys and feed on those they could not catch. When they are full, they come back to warm up on earth, but also to digest, drink fresh water and sleep. They can hold an hour in apnea if they are static and 20 mn if they move. Their tail is flattened for better swimming, and the arrangement of their scales allows them to swim back and forth.
