Length: 1.5-3.6 mm. Body and appendages robust and covered with microtubercles, small median dorsal paired tubercles on pereonite 5, large median paired dorsal paired tubercles on pereonites 6 and 7. Antenna 1 approx length of pereonites 1 and 2; antenna 2 slightly shorter and with swimming setae. Gnathopod 1 propodus grasping margins serrate, with 2 grasping spines. Gnathopod 2 propodus grasping margin with 2 proximal grasping spines and medial notch; dactylus massive, scimitar-shaped and serrrate. Gills oval. Pereopods 5 - 7 stout; propodus with 2 proximal grasping spines.
Boiler Bay, Oregon; California
Named in honor of one of the collectors of the holotype: Dennis S. Greenley.
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.
Found on coralline algae and bryozoans; rarely on sea star Henricia
Unusually small

Caprella greenleyi 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 og to små antenner. De lever bare i havet (saltvann).
Arten kan bli 1,5 - 4 mm lang og den lever i farvann ved Oregon og i California.
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]
