Giant Red Mysid

The giant red mysid is the largest crustacean that lives in open water.Giant red mysids live in deep waters below the tropical and subtropical waters of the Atlantic, Pacific, and Indian oceans.



Mostly these are distributed in tropical and temperate seas worldwide, at depths of 1,300-2,950 feet (396-900 meters).

A mysid might seem like an easy meal for a hungry fish with big teeth. But this shrimplike animal packs a secret weapon. When a fish threatens to eat it, a mysid spits out glowing fluid. The sudden flash of light distracts the attacker and gives the mysid time to swim away.
