Kingsley , 1878

The subfamily of the partner shrimp (Pontoniinae) contains around 35 genera with around 200 species . Almost all of them live in coral reefs , mostly as obligatory commensals with other invertebrates , such as sponges , sea ​​anemones , hydrozoans , hard and soft corals , molluscs , echinoderms and sea ​​squirts . However, it can also be parasitism . A few species like the cleaner shrimp clean fish. A few species are predatory on the smallest prey.

The partner shrimp living in communities are often adapted in color and body shape to the host. Many have the color of the host, species living in cnidarians such as the genus Periclimenes are often translucent with only a few spots of color on the body. Partner shrimp that live in sponges have a cylindrical body in order to be able to move in the tubes inside the sponges. The inhabitants of coral spaces are flattened in order to be able to use the smallest gaps.
