Nursehound
The nursehound (''Scyliorhinus stellaris''), also known as the large-spotted dogfish, greater spotted dogfish or bull huss, is a species of catshark, belonging to the family Scyliorhinidae, found in the northeastern Atlantic Ocean. It is generally found among rocks or algae at a depth of . Growing up to long, the nursehound has a robust body with a broad, rounded head and two dorsal fins placed far back. It shares its range with the more common and closely related small-spotted catshark (''S. canicula''), which it resembles in appearance but can be distinguished from, in having larger spots and nasal skin flaps that do not extend to the mouth. Nursehounds have nocturnal habits and generally hide inside small holes during the day, often associating with other members of its species. A benthic predator, it feeds on a range of bony fishes, smaller sharks, crustaceans, and cephalopods. Like other catsharks, the nursehound is oviparous in reproduction. Females deposit large, thick-wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scyliorhinus Cervigoni
The West African catshark (''Scyliorhinus cervigoni'') is a catshark of the family Scyliorhinidae. It is found in the eastern Atlantic between latitudes 20° N and 17° S, at depths between 45 and 500 m. It can grow up to a length of .

It has no nasoral grooves, the flap that covers the nostrils extends just as far as the mouth and there are labial furrows on the lower jaws only. The front edge of the anterior dorsal fin is immediately above the posterior end of the pelvic fin. The gap separating the two dorsal fins is about the same length as the ...

Scyliorhinus Haeckelii
The freckled catshark (''Scyliorhinus haeckelii'') is a catshark of the family Scyliorhinidae. It is found on the continental shelf and upper slope from the western Atlantic from western Venezuela, Suriname, Brazil, and Uruguay, between latitudes 11° N and 32° S. However, specimens from the northern part of this range probably refer to other species. Description The freckled catshark ranges from 10 to 13 cm long as a hatchling and can range from 25 to 60 cm as it reaches maturity. It is known for its long slender body and for its dark saddles with small black dots covering the dorsal area. The head of the shark contains no nasoral grooves and the small nasal flaps of the shark do not reach its mouth. Their mouth contains grooves on the lower lip only. The first dorsal fins are located behind the pelvic insertions and the second are located anterior to anal insertion. The second dorsal fin is smaller than the first.

Scyliorhinidae
Scyliorhinidae is a Family (biology), family of sharks, one of a few families whose members share the common name catsharks, belonging to the Order (biology), order Carcharhiniformes, the ground sharks. Although they are generally known as catsharks, some species can also be called dogfish due to previous naming. However, a dogfish may generally be distinguished from a catshark as catsharks lay eggs while dogfish have live young. Like most bottom feeders, catsharks feed on benthic invertebrates and smaller fish. They are not harmful to humans. The family is paraphyletic, containing several distinct lineages that do not form a monophyletic group. Genera Scyliorhinidae includes the following genera: * ''Cephaloscyllium'' Theodore Gill, T. N. Gill, 1862 * ''Poroderma'' Andrew Smith (zoologist), A. Smith, 1838 * ''Scyliorhinus'' Henri Marie Ducrotay de Blainville, Blainville, 1816 Anatomy and appearance Scyliorhinidae catsharks may be distinguished by their elongated, cat- ...

Scyliorhinus Capensis
The yellowspotted catshark (''Scyliorhinus capensis'') is a rare catshark of the family Scyliorhinidae. It is found in the southeast Atlantic, from Lüderitz, Namibia to central Natal, South Africa, between latitudes 0° and 37° S. It can grow up to a length of about . The reproduction of this catshark is oviparous. Description The yellowspotted catshark is a long slender fish with rough skin. The upperparts are light grey, copiously spotted with small golden-yellow spots. There are eight or nine dark patches on the back which bridge the spine. The underside is cream-coloured. Small flaps cover the nostrils but do not extend as far as the mouth and there are no nasoral grooves. There are two triangular dorsal fins, the front one considerably larger than the rear one. Distribution and habitat The yellowspotted catshark is found in the seas around the coast of southern Africa at depths down to about . Its range extends from Lüderitz in Namibia to central Natal.

Scyliorhinus Boa
The boa catshark (''Scyliorhinus boa'') is a catshark of the family Scyliorhinidae.

Scyliorhinus Hachijoensis
The cinder cloudy catshark (''Scyliorhinus hachijoensis'') is a species of catshark from the Pacific Ocean; all specimens identified have been from the area around the Izu Islands, Japan. The species is a close relative of the cloudy catshark (''S. torazame''), and the overall appearance is similar. The species was first identified in 2022 as bycatch of the splendid alfonsino fishery. The cinder cloudy catshark is genetically similar to the cloudy catshark, but can be differentiated based on the coloration pattern from all other species within the genus. The term "cinder" refers to Cinderella, specifically the flecks of grey in the coloration pattern which are reminiscent of cinders. The species has the same specialized hooks in its clasper morphology which distinguishes the cinder cloudy catshark and cloudy catshark from the rest of the genus. The Latin name comes from Hachijō-jima, an island near where many of the specimens were collected. Physical description The ...
