The Oman Bullhead Shark (Heterodontus omanensis) is known only from central Oman. It was relatively recently described from three specimens collected at 72 m depth. It is a potential bycatch of demersal fisheries operating within its range, although no specific information is currently available. Insufficient information is available to make an assessment beyond Data Deficient at present and information is required on its biology, abundance and full range, capture in fisheries and population trends.
