биология     глоссарий (например epibenthic)

Inhabits intertidal areas and to 165 m depth, in tide pools and rocky areas but also sand bottoms (Ref. 2850). Frequently observed taking shelter in empty shells, including those of the giant barnacle, Balanus nubilis, and discarded bottles and cans (Ref. 48784). Young feed on zooplankton and invertebrate and fish larvae; adults feed also feed on crustaceans (Ref. 28499). May use its pectoral fins to crawl over rocks and seaweed (Ref. 6885).

Life cycle and mating behavior Maturities | размножение | Spawnings | Egg(s) | Fecundities | личинки

A female chases a male into a rock crevice. She keeps him there until she lays her eggs (Ref. 28499).
