(See ETYFish); hemiodon: hemi-, from hemisys (Gr.), half; odon (Gr.), tooth, allusion not explained, perhaps referring to how teeth on upper jaw are serrated basally and smooth distally. (See ETYFish).

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 0; Espinas anales: 0. Grey above, white below, with the tips of the pectorals, and upper and lower caudal-fin lobes black; other fins dusky (Ref. 9997).

A little-known shark found on the continental and insular shelves (Ref. 244). Reports from river mouths and rivers are based on old records that need verification (Ref. 9997). Probably feeds on small fishes, cephalopods, and crustaceans (Ref. 9997). Viviparous (Ref. 50449). Utilized fresh for human consumption (Ref. 9997).
