Coral catshark

The coral catshark (''Atelomycterus marmoratus'') is a species of catshark, and part of the family Scyliorhinidae. It is common on shallow coral reefs across the Indo-West Pacific, from Pakistan to New Guinea. Reaching up to in length, the coral catshark has an extremely slender body, a short head and tail, and two dorsal fins that are angled backwards. It can be identified by the numerous black and white spots on its back, sides, and fins, which often merge to form horizontal bars. Furthermore, adult males have distinctively long and thin claspers.
Reclusive and inactive during the day, at dusk and at night the coral catshark actively forages for small, bottom-living invertebrates and bony fishes. Its slender form allows it to access tight spaces on the reef. It is oviparous: females lay purse-shaped egg capsules two at a time on the bottom, and the young hatch after 4–6 months. This small, harmless shark adapts well to captivity and has reproduced in the aquarium; it is regarded as one of the most suitable shark species for private aquarists. The coral catshark is a minor bycatch of reef fisheries, with minimal commercial value. There is increasing fishing activity and extensive habitat degradation within its range, leading to concern over its population and its assessment as Near Threatened by the International Union for Conservation of Nature (IUCN).
==Taxonomy==

The coral catshark was first described by an anonymous author, usually referred to English zoologist Edward Turner Bennett, in the 1830 ''Memoir of the Life and Public Services of Sir Thomas Stamford Raffles''. Its original name was ''Scyllium marmoratum'', from the Latin ''marmoratus'' meaning "marbled".〔〔 Hence, another common name for this species is marbled catshark.〔 In 1913, Samuel Garman placed it in his newly created genus ''Atelomycterus''.〔 The type specimen was caught off Sumatra and is suspected to have been lost.〔
