Pacific Cleaner Shrimp Facts

The Pacific cleaner shrimp is a tropical crustacean found in Indo-Pacific coral reefs. They inhabit crevices and holes, feeding by cleaning dead skin and parasites off fish, including potential predators. They attract clients to cleaning stations by waving their antennae. These shrimp are protandric simultaneous hermaphrodites, maturing first as males and later functioning as both sexes. They have swimmerets for swimming and brooding eggs, with a long larval period.
