Catsharks are ground sharks of the family Scyliorhinidae. They are one of the largest families of sharks with around 160 species placed in 17 genera. Although they are generally known as catsharks, many species are commonly called dogfish or gato. Like most bottom feeders, they feed on benthic invertebrates and smaller fish. Catsharks are not harmful to humans.
Scyliorhinus is a genus of catsharks in the family Scyliorhinidae. This genus is known in the fossil records from the Cretaceous period, late Albian age to the Pliocene epoch.
Apristurus is a genus of catsharks, the family Scyliorhinidae, commonly known as the ghost or demon catsharks.
Halaelurus is a genus of catsharks in the family Scyliorhinidae.
The finback catsharks are a small family, the Proscylliidae, of ground sharks. They can be found in warm seas worldwide and are often the most numerous and common shark in tropical regions. They are generally less than 1 m in length, and are slow-moving predators that feed on bony fish and small invertebrates. Although some bear live young, the majority lay eggs with almost fully developed young; these egg cases, known as "mermaid's purses", are unique in appearance to each species.
Parmaturus is a genus of catsharks in the family Scyliorhinidae. Four species were described in 2007 and another in 2019 with more species likely to be described in the near future.
The graceful catshark is a species of finback catshark, belonging to the family Proscylliidae. This shark is found in the western Pacific Ocean, from southeastern Japan to Vietnam and northwestern Java, at depths between 50 and 100 m. Females can reach a length of 65 cm.
The spotted smooth dogfish is a finback catshark of the family Proscylliidae, found in the temperate northwest Pacific Ocean, in the Okinawa Trough. Little else is known about this harmless oviparous species.
Atelomycterus is a genus of catsharks in the family Scyliorhinidae.
Asymbolus is a genus of catsharks in the family Scyliorhinidae.
Aulohalaelurus is a genus of catsharks in the family Scyliorhinidae.
Galeus is a genus of catshark, belonging to the family Scyliorhinidae, commonly known as sawtail catsharks in reference to a distinctive saw-toothed crest of enlarged dermal denticles, found along the upper edges of their caudal fins. They are found in the Atlantic, the western and central Pacific, and the Gulf of California, inhabiting deep waters at or close to the sea floor. Members of this genus are rather small, slim sharks with firm bodies and thick, rough skin. Their heads are usually fairly long and pointed, and have large mouths with well-developed furrows at the corners. They have large pectoral and anal fins, and two similar dorsal fins placed well back. Many species are ornately patterned with dark saddles and/or blotches. Sawtail catsharks feed on various invertebrates and fishes, and may be either egg-laying or live-bearing. These harmless sharks are sometimes caught as bycatch but are of minimal commercial value.
Holohalaelurus is a genus of catshark in the family Scyliorhinidae, commonly known as Izak catsharks or hallelujah sharks.
Schroederichthys is a genus of catsharks in the family Scyliorhinidae.
The narrowtail catshark is a catshark of the family Scyliorhinidae, found off the coasts of Honduras and Nicaragua, between latitudes 18° N and 10° N, at depths between 190 and 410 m. It can grow up to a length of 35 cm (14 in). The reproduction of this catshark is oviparous.
The dwarf sawtail catshark is a little-known species of catshark, belonging to the family Scyliorhinidae, found exclusively in the deep waters off Luzon in the Philippines. Unlike other members of its genus, this slender, diminutive shark has a short, rounded snout and very short furrows at the corners of its jaws. It has indistinct darker saddles beneath each dorsal fin and two dark bands on the caudal fin, as well as a prominent crest of enlarged dermal denticles along the upper caudal fin margin.
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.
Figaro is a genus of catshark, and part of the family Scyliorhinidae. Until 2008, Figaro was generally considered to be a subgenus of Galeus. The two known species are found off Australia, inhabiting deep, offshore waters on or near the bottom. Figaro contains small, slender, firm-bodied sharks that bear distinctive crests of enlarged, spiny dermal denticles along the dorsal and ventral edges of their short caudal fins. The caudal peduncle is relatively long, such as that the anal and caudal fins are some distance apart. In adult males, the inner margins of the pelvic fins are fused together to form a subtle "apron" over the claspers. F. boardmani is a predator of fishes, crustaceans, and cephalopods, and is oviparous; less is known about the F. striatus. Both are harmless and are of no economic importance.
The magnificent catshark or clown catshark is a species of finback catshark, belonging to the family Proscylliidae, known only from five specimens collected in the northern Andaman Sea near the edge of the Myanmar continental shelf. Its common names refer to its distinctive, elaborate color pattern of small and large dark spots, which include "clown faces" beneath each dorsal fin. Reaching 49 cm (19 in) in length, this species has a very slender body with a short, flattened head and a large lobe of skin in front of each nostril. The first dorsal fin is placed behind the pectoral fins but ahead of the pelvic fins.
