Crinoid shrimp
species of mollusc
The crinoid shrimp, or feather star shrimp Hippolyte catagrapha, is a species of shrimp in the family Hippolytidae
Description
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.
Distribution
These animals are found off the South African coast in False Bay and have been seen from 10 to at least 30 m underwater. They are probably endemic to this area. There is evidence however, that these shrimp exist elsewhere in the world with the species recently observed in the Philippines.
Ecology
These shrimps have so far only been seen in association with crinoids. They probably eat the wastes of their host.
This brief starts where responsible research should: with the source description of “Crinoid shrimp” as species of mollusc. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of mollusc. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated May 19, 2026. The linked authority identifier is Q13231726. None of the 0 selected statements returned an explicit reference.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
