Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 6 - 7; Mjukstrålar i ryggfenan (totalt) : 9 - 11; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 8 - 10. Caudal narrow and rounded; pectorals with a long base extended to ventral surface, all rays slightly exserted, ventral ones more so; pelvic fins with rays ossified and modified to support all of a large adhesive disc with thickened fringed margin (Ref. 6885). Light to dark green, sometimes light brown dorsally; light brown or plum ventrally; lips lavender; tubercles in males dull orange or reddish brown; tubercles in females are larger and more numerous and pale green (Ref. 6885).
Commonly inshore; often found at low tide attached to rocks (Ref. 2850).
