Habitat and Ecology:

Habitat and Ecology

This is a solitary, nocturnal species (Bailey 1974). It is widespread in both coastal and offshore waters. It feeds on benthic animals, with chironomid larvae as major food item (Bailey 1994). It has a curious habit of swimming backwards. It spends the day on the bottom, but after nightfall it becomes very active, searching for food. Associated with rocks and is commonly caught in rapidly-flowing water. Males outnumber females in the catch. Gonads are mature in spring and summer and only the left ovary or testis is present. Well grown fish can give quite an electrical shock.
