Diagnostic Description ( englanti )

tarjonnut 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 ( englanti )

tarjonnut 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 ( englanti )

tarjonnut 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.

Caprella scaura ( norja )

tarjonnut wikipedia NO

Caprella scaura er en art i slekten Caprella innenfor spøkelseskreps-familien (orden Caprelloidea eller «spøkelsestanglopper») - en type tanglopper. Larvene er planktoniske. De er relativt små, med to store ot to små antenner. De lever bare i havet (saltvann).

Arten kan bli 6 - 21 mm lang og den lever ned til 16 meters dyp i farvann i nesten hele tropene , inklusive Atlanterhavet, Middelhavet, Indiahavet, og Stillehavet (nord til Russland).

Taksonomisk plassering

Slektens systematikk er i nyere tid beskrevet og oppdatert i 2003.[1] Artens moderne tilhørighet i Caprella-krepsenes systematikk gis nedenfor i lys av 2013-revisjonen med basis i WoRMS-databasen. [2]
