The rostral organ of the coelacanth or similar in many other fish such as Anchovy is a large gel-filled cavity in the snout, with three pairs of canals to the outside. [1]
It is surrounded by an insulating layer of adipose tissue and innervated by the superficial ophthalmic nerve. Its anatomy and innervation suggest it is an electroreceptive organ [2] used for finding prey in the dark. This is supported by experiments which showed that coelacanths react to electrical fields produced by a submersible. [2]
