Squalidae, also called dogfish sharks, dog sharks, or spiny dogfish, are a family of sharks in the order Squaliformes. Dogfish sharks make up the second largest order of sharks at 119 species. They have two dorsal fins, each with smooth spines, but no anal fin, and their skin is generally rough to the touch. Dogfish tend to have slender bodies with a pointed snout. These species are also known to be more compact in comparison to other sharks. As the species reaches adulthood, males usually measure in at a maximum of 39 inches (990 mm), while females typically measure 49 inches (1,200 mm) long. This classifies the species as having a female-dominant sexual dimorphism. Dogfish sharks earned their name after a group of fishermen observed the species chasing down smaller fish in dog-like packs.

The spiny dogfish, spurdog, mud shark, or piked dogfish is one of the best known species of the Squalidae (dogfish) family of sharks, which is part of the Squaliformes order. While these common names may apply to several species, Squalus acanthias is distinguished by having two spines and lacks an anal fin. It is found mostly in shallow waters and further offshore in most parts of the world, especially in temperate waters. Spiny dogfish in the northern Pacific Ocean have recently been reevaluated and found to constitute a separate species, now known as "Pacific spiny dogfish", Squalus suckleyi.
Squalus is a genus of dogfish sharks in the family Squalidae. Commonly known as spurdogs, these sharks are characterized by smooth dorsal fin spines, teeth in upper and lower jaws similar in size, caudal peduncle with lateral keels; upper precaudal pit usually present, and caudal fin without subterminal notch. In spurdogs, the hyomandibula is oriented at a right angle to the neurocranium, while in other sharks, the hyomandibula runs more parallel to the body. This led some to think that the upper jaw of Squalus would not be as protractile as the jaws of other sharks. However, a study that compared different jaw suspension types in sharks showed that this is not the case and that Squalus is quite capable of protruding its upper jaw during feeding.
The mandarin dogfish is a dogfish, a member of the family Squalidae in the order Squaliformes. It is found at depths of 140–650 metres (460–2,130 ft) off southern Japan, Taiwan, and Indonesia. Populations off Australia and New Zealand were formerly included in this species, but in 2007 these were assigned to a new species, the southern Mandarin dogfish. It is not clear which of these species is involved in other populations from the tropical West Pacific.
The Cuban dogfish is a dogfish, a member of the family Squalidae in the order Squaliformes. It is found in the Western Atlantic from North Carolina to Florida, in the Gulf of Mexico, around Cuba, Hispaniola, southern Brazil, and Argentina. It inhabits continental shelves and uppermost slopes at depths from 60 to 380 m.
The roughskin spurdog is a dogfish of the family Squalidae, found circumglobally between latitudes 35°N and 35°S, at depths of between 200 metres (660 ft) and 600 metres (2,000 ft). It reaches a length of 1.2 metres (3.9 ft).
Cirrhigaleus is a genus of sharks in the Squalidae (dogfish) family, which is part of the Squaliformes order.
The viper dogfish or viper shark is a rare species of dogfish shark in the family Etmopteridae, and the only extant member of its genus. It has been found in the Pacific Ocean off southern Japan, the Bonin Islands, Pacific Ocean off northern Taitung County and the Northwestern Hawaiian Islands. This species inhabits upper continental slopes and seamounts. It may migrate vertically, shifting between bottom waters 270–360 m (890–1,180 ft) deep during the day and upper waters less than 150 m (490 ft) deep at night. A slender, black shark reaching 54 cm (21 in) in length, the viper dogfish can be recognized by its narrow, triangular jaws and well-spaced, fang-like teeth. It also has two spined dorsal fins, dermal denticles with faceted crowns, and numerous light-emitting photophores concentrated on its ventral surface.
The Japanese spurdog is a dogfish, a member of the family Squalidae. It is found in the western Pacific Ocean – southeastern Japan and the East China Sea, including the Republic of Korea, the Philippines, and the Arafura Sea.
The shortspine spurdog is a dogfish, a member of the family Squalidae, found on continental shelves off Japan in temperate waters, from the surface to 950 m. Its length is up to 75 cm.
The bartail spurdog is a dogfish of the family Squalidae, found on the continental shelf off Queensland, Australia, at depths between 220 and 450 m. The length of the longest specimen measured, an immature male, is 62 cm (24 in). Its reproduction is ovoviviparous .
The eastern highfin spurdog is a dogfish described in 2007. It is a member of the family Squalidae, found on the continental shelf off Queensland, Australia, at depths between 220 and 510 m. The length of the longest specimen measured is 65 cm (26 in). Its reproduction is ovoviviparous.
The western highfin spurdog is a dogfish of the family Squalidae found on the continental shelf off Western Australia, at depths between 220 and 510 m. Its reproduction is ovoviviparous.
The fatspine spurdog is a dogfish of the family Squalidae, found on the continental shelf off the northern coast of Western Australia, at depths of 180 to 200 metres. The length of the longest male specimen measured is 56 centimetres (22 in).
The western longnose spurdog is a dogfish of the family Squalidae, found on the continental shelf off the northwest and southwest coasts of Western Australia, at depths between 300 and 510 m. Its length is at least 55 cm.
The eastern longnose spurdog is a dogfish of the family Squalidae, found off northern Queensland, at depths between 220 and 500 m. Its length is up to 64 cm. Its reproduction is ovoviviparous.
The southern Mandarin dogfish is a species of Mandarin dogfish shark in the genus Cirrhigaleus. It was distinguished from Cirrhigaleus barbifer, which lives in the North Pacific, on an expedition in the coral reefs near Australia in 2007. It is now known to live in the temperate waters in south-eastern Australia and from the Bay of Plenty region in New Zealand, at depths of 146–640 metres.
The Pacific spiny dogfish is a common species of the Squalidae (dogfish) family of sharks and are among the most abundant species of sharks in the world. This species is closely related to Squalus acanthias and for many years they were treated as a single species. Recent research, using meristic, morphological and molecular data led to the resurrection of Pacific Spiny Dogfish as a separate species. The American Fisheries Society recommends the common name "Pacific Spiny Dogfish" for Squalus suckleyi over alternatives such as "Spotted Spiny Dogfish" and "North Pacific Spiny Dogfish" and "Spiny Dogfish" for Squalus acanthias.
The northern spiny dogfish, also known as brown dogfish, grey spiny dogfish, or Griffin's dogfish is a dogfish described in 1931. It is a member of the family Squalidae, found off New Zealand. The length of the longest specimen measured is 89.9 cm (35.4 in).
