Most of the time the fish spends waiting for prey perfectly still having hidden at the bottom, almost merging with it. It feeds mainly on various fish and cephalopods (squid and cuttlefish), occasionally eating carrion. Firstly, US offshore devils spawn with an average body length of 46.5 cm. Spawning takes place in May or June. The eggs are 1.5-1.8 mm in diameter, sewn in the mucous tape, reaching 12 m in length and 60 cm in width. Masonry consists of 1-3 million eggs drifting on the surface of the ocean for 6-100 days, depending on the water temperature, until the larvae begin to hatch. The young fish leads pelagic, feeding on zooplankton. Upon reaching the length of 7cm, they begin to change their appearance, for a few weeks taking the form of adult fish body and going to the bottom of life. Anglers grow rapidly during their first year of life, after that their rate of growth slows down.
