Arabian Catshark

The Arabian catshark is a mysterious species of catshark found on the open seas. All the information on this fish comes from a single specimen, caught in the Arabian Sea, now lost though.

Arabian Catshark Scientific Classification

Kingdom Animalia
Phylum Chordata
Class Chondrichthyes
Order Carcharhiniformes
Family Scyliorhinidae
Genus Bythaelurus
Scientific name B. alcockii


The only specimen discovered was 30 cm (12 in), which is assumed to be the maximum length attained by this species. It has a similar appearance to the Bristly catshark. The main difference lies in its longer snout, smaller eyes, and anal fin; the second dorsal fin is slightly larger than the first. It has a black body with a hoary grey surface. The tips of some fins are white.

Where do they live

It is found in the northern Indian Ocean, specifically in the Arabian Sea. It inhabits the continental shelf at depths of 1,134-1,262 m (3,720-4,410 ft).



Researchers think it follows an oviparous mode of reproduction like other members in its genus. The size of its litter is unknown.


Like other sharks, they are presumed to have a keen sense of smell and sight, sharp teeth, and a streamlined body.

Human interactions

They have no commercial benefits and are harmless to humans. There is no information about their population and life cycle, so the IUCN has marked them as “Data Deficient” or “DD.”
