unusual facts about Fish anatomy


Shark anatomy

Shark anatomy has points of difference with the anatomy of bony and other types of fish.


Diplomystidae

Diplomystids are the only extant catfish family with teeth on a well-developed maxilla (although this is also true of the extinct genus Hypsidoris).

Fin rot

Fin rot can be the result of a bacterial infection (Pseudomonas fluorescens, which causes a ragged rotting of the fin), or as a fungal infection (which rots the fin more evenly and is more likely to produce a white 'edge').
