The sombre catshark (Bythaelurus incanus) is a species of catshark in the family Scyliorhinidae. It is known from a single specimen south of Rote Island, northwestern Australia. Its natural habitat is the open seas.
The New Zealand catshark is a catshark of the family Scyliorhinidae in the order Carcharhiniformes. This species is endemic to in the deep waters around New Zealand. Its length is up to 45 centimetres (18 in). The New Zealand catshark is a small, little-known deep water bottom shark. It is dark brown around the top with a few widely spaced pale spots, and white below. It feeds on bottom-living crustaceans. It is also completely harmless to humans.
The Australian spotted catshark is a catshark of the family Scyliorhinidae, found only around Australia between 32 and 38°S, at depths between 10 and 180 m. It can grow up to 90 cm. Females of this species were observed as being reproductive year round. They are also confirmed as being a single oviparous species.
The orange-spotted catshark or rusty catshark, is a species of catshark, and part of the family Scyliorhinidae. It is found only off the coast of Western Australia, at depths between 25 and 540 m. Its length is up to 39 cm (15 in).
The Arabian catshark is a catshark of the family Scyliorhinidae. It can grow up to 30 centimetres (12 in) long, and lives in open seas. It is only known from a single specimen, now lost, which was found on the continental slope of the Arabian Sea.
The spotless catshark is a catshark of the family Scyliorhinidae found in the South China Sea at depths between 535 and 1,020 m on the continental slope. Its length is up to 71 centimetres (28 in).
The bristly catshark is a cat shark of the family Scyliorhinidae, found from southeastern India and the Andaman Islands, between latitudes 15° N and 5° N, at depths between 200 and 300 m. Its length usually ranges from around 20–26 cm, and it is regarded as the smallest catshark of Bythaelurus.
The dusky catshark is a catshark of the family Scyliorhinidae that is endemic to the southeast Pacific Ocean, off the coasts of Peru and Chile. It grows to a maximum length of 70 cm, and is oviparous like many other chondrichthyans in the Indo-Pacific.
The bulldog catshark is a catshark of the family Scyliorhinidae, found in the deep waters of the East China Sea and in the Northwest Pacific. In New Zealand waters it is found at the Reinga Ridge, the West Norfolk Ridge, the Hikurangi Trough and the Chatham Rise as well as on the Campbell Plateau.
The South China catshark is a catshark of the family Scyliorhinidae, known only from the holotype, which was taken from the South China Sea at a depth of 537 m. Its length is 42 cm, but this measurement was taken from an immature specimen. The reproduction of the South China catshark is oviparous.
The ghost catshark is a catshark of the family Scyliorhinidae found on the continental slopes in the northwest Atlantic off Massachusetts, the northeast Atlantic from the Porcupine Bank west of Ireland and the southern Atlantic off Cape Town, at depths between 600 and 1,900 metres.
The spatulasnout catshark, also known as the Borneo catshark or flatnose catshark, is a catshark of the family Scyliorhinidae, found in the western Pacific between 35°N and 1° N. Its length is up to 80 cm.
Bythaelurus is a genus of deep-water catsharks and part of the family Scyliorhinidae. The genus Bythaelurus Compagno 1988 was first described as a subgenus of Halaelurus Gill 1862 based on several morphological characteristics including a soft body with thin skin, a bluntly rounded snout without a pointed, knob-like tip, and eyes not noticeably elevated on the dorsal surface of the head. Members of this genus are generally found in deep water and have more somber body coloration.
The broadhead catshark is a catshark of the family Scyliorhinidae. The only specimen, the holotype, was found off Madagascar at a depth between 425 and 500 m.
The mud catshark or brown catshark is a species of catshark in the family Scyliorhinidae. It is found in Mozambique and Somalia. Its natural habitat is the open seas of the western Indian Ocean, from Mozambique to Somalia, between latitudes 13° N and 29° S, at depths between 340 and 765 m. It can grow up to 34 centimetres (13 in) long.
The jaguar catshark, also known as the Galápagos catshark, is a species of catshark from the Galápagos Islands. The species was first described in 2012. This catshark is about a foot long when mature, and it is colored blackish-brown with an asymmetrical pattern of light spots.
The narrowhead catshark is a catshark of the family Scyliorhinidae. This species is described based on one adult and one juvenile male specimen from off Tanzania and Mozambique in the western Indian Ocean. The species differs from its congeners by its slender head and snout, which is only slightly bell-shaped in dorsoventral view without distinct lateral indention. It further differs from B. clevai by attaining a smaller maximum size and having a color pattern of fewer and smaller blotches, larger oral papillae, a shorter snout, and broader claspers without knob-like apex and with a smaller envelope and a subtriangular exorhipidion. Compared to B. hispidus, the species has a longer snout, a longer dorsal-caudal space, broader clasper without knob-like apex, and fewer vertebral centra. In contrast to B. lutarius, B. tenuicephalus attains a smaller size and has a blotched coloration, numerous oral papillae, shorter anterior nasal flaps, a longer caudal fin, a shorter pelvic anal space, and shorter and broader claspers.
Bythaelurus stewarti, the Error Seamount catshark, is a catshark of the family Scyliorhinidae in the order Carchariniformes. It is endemic to Error Seamount, a guyot located in the Arabian Sea in the western Indian Ocean. Its closest relative is the bristly catshark, which it differs from in its larger size, darker and more mottled coloration, and especially its smaller and less densely concentrated denticles.
Bythaelurus bachi, commonly known as Bach's catshark, is a species of catshark found in southern Madagascar Ridge in the southwestern Indian Ocean. This stout-bodied catshark is thought to inhabit the deep sea at depths of 910–1,365 m (2,986–4,478 ft).
Bythaelurus vivaldii, Vivaldi's catshark, is a species of catshark found in Northwestern Indian Ocean, specifically in Somalia. It presumably lives in the depths of up to 628 m (2,060 ft).
