Rostral organ

Rostral organ

The rostral organ of the coelacanth is a large gel-filled cavity in the snout, with three pairs of canals to the outside. 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 [ [http://links.jstor.org/sici?sici=0045-8511(19820528)3:1982:2%3C467:TROOLC%3E2.0.CO;2-Z The rostral organ of "Latimeria chalumnae": morphological evidence of an electroreceptive function] ] , used for finding prey in the dark. This is supported by experiments which showed that coelacanths react to electrical fields produced by a submersible. Fact|date=February 2008

This organ is not known in any other animal.
