Feeding behavior of 3 species of the Artedidraconidae, Artedidraco skottsbergi, Histiodraco velifer and Pogonophryne marmorata was observed in a laboratory. H. velifer and P. marmorata responded to touching their mental barbel with fresh krill and their feeding behavior seemed to be evoked with the stimuli received by the barbel in the light condition. The observed motion of the barbel likely indicated that the barbel of the two species of artedidraconids functioned as an antenna or a sensor to perceive prey organisms. A. skottsbergi did not show any action responding to the prey supplied in a tank.
