Length: 10-23 mm. Cephalon smooth; pereonite 2 with small pair spines dorsal to insertions of gnathopods 2 and anteriorly directed long pair of spines at posterior end; pereonite 3 with 2 pairs short spines medianly and 1 pair anteriorly directed long spines at posterior end; pereonite 4 with 3 pairs short spines medianly and a single anteriorly directed projection at posterior end; pereonite 5 with 2 pairs projections (median and posterior); pereonites 6 with 3 pairs small projections; pereonite 7 with a single pair of small projections. Antenna 1 a little longer than ½ body length; antenna 2 shorter than antenna 1 peduncle. Gnathopod 2 propodus with proximal grasping spine and accessory spine, distal ‘tooth’ and triangular projection. Gills elongate.
Sea of Japan: Sakhalin Is., China, Japan, Vladivostok.
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.
One of the most common Caprellid species in northern Japan.
Caprella bispinosa is een vlokreeftensoort uit de familie van de Caprellidae.[1] De wetenschappelijke naam van de soort is voor het eerst geldig gepubliceerd in 1903 door Mayer.

Caprella bispinosa 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), og er utbredt i farvannene ved Japan og Sakhalin.
Arten ble oppdaget under Siboga-ekspedisjonen. Den er 10-23 mm lang.
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]
