Maturity: Lm ?  range ? - ? cm
Max length : 8.9 cm TL male/unsexed; (Ref. 5294); common length : 6.0 cm TL male/unsexed; (Ref. 5294)
Eastern Atlantic and Mediterranean Sea: English Channel southwards and along the coast of west Africa, including Madeira and the Canary Islands (Ref. 4785), south to Senegal.
Inhabits shallow coastal waters with rocky substrate. Found under overhanging rocks, entrances of caves and other biotopes with reduced light. In the Atlantic, it also occurs in shallow, light-exposed biotopes. Feeds on benthic invertebrates, also on harpacticoids. Males court by figure-8-swimming (Ref. 4785).
