The Oman bullhead shark, Heterodontus omanensis, is a bullhead shark of the family Heterodontidae, found in the tropical western Indian Ocean around central Oman from the surface to 70 m. Its length is up to 56 cm.
The Oman bullhead shark has large pectoral fins, and a unique egg case, with 2 long tendrils extending from its base and flanges with 2 turns. This species differs from the Japanese bullhead shark in having 4 dark saddles (versus 11 to 14); a smaller first dorsal fin (9.3% to 10.9% of total length versus 11% to 21%); an egg case of 2 turns (versus 3) bearing extremely long tendrils.
Coloration is four dark saddles, more or less equally distributed along the head and body. Relatively small, dark pigmented dorsal fins, each with a white distal streak.
