Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 83 - 84; Mjukstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 1; Mjukstrålar i analfenan: 32 - 38. Caudal rounded. Pectorals small.
Facultative air-breathing (Ref. 126274); Intertidal (Ref. 31184), commonly found in rockweed (Fucus) masses, in tide pools and inshore areas. May remain out of water under rocks or seaweed (Ref. 31184). Feeds on small crustaceans and mollusks. Breathes air (Ref. 31184) and can stay out of water for 5-20 hours if kept moist (Ref. 51276).
