Behavior

As other sea robins, grey gurnards produce sounds. Sound production in this species is often associated with competition for food. Small individuals produce more sounds than larger ones, and emit more "grunts" than "knocks", probably because they more often compete for food by contest tactics whereas larger specimens predominantly scramble for food.
