An frogfish (Antennarius sp.) as a mimic of sea urchins: a new form of mimicry in the family Antennariidae

Frank Schneidewind

aqua, International Journal of Ichthyology, pp. 23-28, Volume 10, Issue 1 – June 2005


Mimicry in frogfishes (Antennariidae) and  defensive associations between fishes and sea urchins, and a black, “hairy” frogfish (Antennarius sp.) from the Philippines are described. This  mimic frogfish lives in the middle of a colony of sea urchins (Astropyga radiata). Its external appearance and its behaviour are interpreted as a form of aggressive and protective mimicry, as well as camouflage, previously unknown in frogfishes.
