Skeleton shrimp are abundant and live in many habitats, including the deep sea. They play an important role in the ecosystem by eating up detritus and other food particles.
Shrimp, sea anemones and surfperch prey on skeleton shrimp. The females of some skeleton shrimp species kill the male after mating.
Skeleton shrimp use their front legs for locomotion. To move, they grasp first with those front legs and then with their back legs, in inchworm fashion. They swim by rapidly bending and straightening their bodies.
To grow, skeleton shrimp shed their old exoskeletons and form new, larger ones. They can mate only when the female is between new, hardened exoskeletons. After mating, the female deposits her eggs in a brood pouch formed from leaflike projections on the middle part of her body. Skeleton shrimp hatch directly into juvenile adults.
