Dichichthys
Genus of sharks
From Wikipedia, the free encyclopedia
Dichichthys is a genus of sharks which is the only genus in the monotypic family Dichichthyidae, the bristle sharks. These sharks are found in the Western Pacific Ocean. Until recently, scientists believed these 5 species were part of the genus Parmaturus, until morphological testing confirmed its placement in its own family. Supraorbital crests on the chondrocranium also distinguish Dichichthys from other catshark genera/families.[1]
