Pristiophorus is a genus of sawsharks found in the Pacific, Atlantic and Indian oceans. Members of this genus differ from sixgill sawsharks of the genus Pliotrema in having five gill slits. Their rostral sawteeth lack prominent transverse ridges on the basal ledges, and the large teeth are not posteriorly serrated.[1]
Taxonomy
[edit]The genus name Pristiophorus comes from Ancient Greek pristēs, meaning "saw", and -phóros, meaning "bearing".
