Diagnostic Description

provided by Caprellids LifeDesk

Length: 6-21mm. Head with anteriorly directed spine, female with variously developed spines on pereonites 1-7. (E.g., pereonite 3 with antero- and postero- lateral projections; pereonite 4 with antero-lateral projections and extended over pereonite 5 at posterior end; pereonite 5 with two pairs dorsal projections; pereonites 6 + 7 each with 2 pairs dorsal projections.) Antenna 1 longer than ½ body length; antenna 2 length variable. Propodus of gnathopod 1 with 2 proximal grasping spines, grasping margin of dactylus and propodus serrate. Propodus of gnathopod 2 elongate in males (apparent ‘knuckle’), palm with proximal and median strong teeth and distal rectangular projection; dactylus sculpted also. Gills elliptical. Pereopods 5 - 7 propodus with 2 proximal grasping spines. Females differ in gnathopod 2: not so elongate, palm with proximal spine, small distal tooth and distal rectangular projection.

General Description

provided by Caprellids LifeDesk

Caprellid, "Ghost" or "Skeleton" shrimps, so called for their skeletal appearance. Amphipod crustaceans, easily distinguished by the elongate stick-like body form and reduction of the abdominal appendages. Head is generally fused with pereonite 1. Pereopods on first 2 segments (pereonites) are most flexible and called gnathopods; gnathopods 2 being the largest, used in defense, feeding and substrate attachment. In many species pereopods 3 and 4 may also be reduced or absent. Gills on pereonites 3 + 4, rarely on pereonite 2. Pereopods 5 - 7 much smaller than 1 + 2, used for clinging to the substratum. In females, brood plates (öostegites) develop on pereonites 3 + 4. Much remains to be learnt about their biology, ecology and in many cases changing distributions.

Notes

provided by Caprellids LifeDesk

A species complex reminiscent of C. equilibra and C. natalensis; introduced to San Francisco Bay and Elkhorn Slough; 7 varieties described by Mayer- of which, C. californica Stimpson, 1857 was re-established by McCain (1968) who also remanded the others as junior synonyms.
