Length: 10.1mm. Body with small tuberculations dorsally on pereonites 1 to 5, ventrally on pereonites 2, 3 and 4. Unpaired spines present dorsally at mid-length of pereonites 2 to , and laterally anterior of pereonites 3 and 5. Antenna 1 peduncle articles 2 and 3 slightly setose. Gnathopod 2 of female with large anterolateral spine on basis; prpodus with proximal projection with grasping spine and accessory spine, and medial and distal low projections, palm slightly setose; dactylus quite heavy. Gills slender, elliptical. Pereopods 5 - 7 with proximal pair of grasping spines on propodus.

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.

Caprella rinki 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 10 mm lang og den lever ned til 1.500 meters dyp i farvann ved Grønland og Canada (Labrador).
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]
