The crinoid shrimp, or feather star shrimp[1] Hippolyte catagrapha, is a species of shrimp in the family Hippolytidae[2] Crinoid shrimps grow to up to 3 cm in total length.

They are well camouflaged shrimps which live on a host crinoid, the elegant feather star, Tropiometra carinata.

[3] These animals are found off the South African coast in False Bay and have been seen from 10 to at least 30 m underwater.

[3] There is evidence however, that these shrimp exist elsewhere in the world with the species recently observed in the Philippines.
