Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 15.5 cm TL macho/indeterminado; (Ref. 106276)
No overlap of dorsal and caudal fins, but rarely overlapping anal and caudal fins (Ref. 35388).
Occurs from intertidal to 30 m, often under stones or clinging to algae. Feeds primarily on crustaceans; gammarid amphipods in intertidal; shrimps and small crabs in subtidal areas. Spawns in winter; young are also found in the Wadden sea (Ref. 35388).
Eggs are deposited on algae or polyp colonies.
