Rostral, in the case of this article as it stands 9 Mar 2009, is used as a descriptive (adjective) modifier of the word "organ" and thus should not be confused as a "named organ" (like "liver", "pancreas", "rostral organ" - NO!!) because, rostral is a location description. If you look up the word at Anatomical terms of location you will understand this fact. So, the coelacanth may have its unique rostral organ, which may not be known in any other animal, but there may still be other rostral organs in other animals. Take, for example, the one found in the anchovy. 3FreeFish (talk) 16:13, 9 March 2009 (UTC)Reply
