Giant Red Shrimp

Neognathophausia ingens

A crimson crustacean launches a glowing smoke screen.

The giant red shrimp is really a giant lophogastrid, a shrimp-shaped kind of crustacean. Its deep crimson shell and clever chemistry suit the dark, low-oxygen ocean.

Tell-your-friends facts

Four wonderfully wild things

  1. 1

    It is a lophogastrid crustacean rather than a true decapod shrimp.

  2. 2

    Red coloring appears nearly black in deep water, making useful camouflage.

  3. 3

    Its oxygen-carrying hemocyanin works especially well where oxygen is scarce.

  4. 4

    Like other lophogastrids, females protect developing young in a brood pouch.

Ocean superpower

Built to be amazing

When threatened, it releases a glowing blue cloud that can confuse a hunter.

Junior scientist tip
