Crinoid shrimp

Scientific name : Periclimenes cf. cornutus

This shrimp belongs to a group of many species, all commensal of crinoids, difficult to identify without a microscopic examination. We give some tips to give a name to some of the more important species, keeping into account that an identification based only on a photography cannot be sure.
P. cornutus has often a colour pattern with large white-black-yellow-red blotches, matching the host colour. Identified also by the size of the claws, large, stout and unequal. Body is short. 1.5 cm.
Very easy to confound with anyone of the Periclimenes species living as commensals on crinoids. Compared with Periclimenes amboinensis and Periclimenes ceratophthalmus (both described in this site) is identified by the shorter body, the cololur pattern with large blotches, the large unequal claws.
