The prickly shark is one of the two species of sharks in the family Echinorhinidae, found in the Pacific Ocean over continental and insular shelves and slopes, and in submarine canyons. Bottom-dwelling in nature, it generally inhabits cool waters 100–650 m (330–2,130 ft) deep, but it also frequently enters shallower water in areas such as Monterey Bay off California. This stocky, dark-colored shark grows up to 4.0 m (13.1 ft) long, with two small dorsal fins positioned far back on its body and no anal fin. It is characterized by a dense covering of thorn-like dermal denticles, hence its common name.

The pygmy shark, the second-smallest of all the shark species after the dwarf lanternshark, is a squaliform shark of the family Dalatiidae, the only member of the genus Euprotomicrus. Their lengths are up to about 25 cm (10 in) for females and about 22 cm (8.7 in) for males.
Apristurus is a genus of catsharks, the family Pentanchidae, the deepwater catsharks. The species in this genus are commonly known as the ghost or demon catsharks.
The New Zealand catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks, 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 spotted estuary smooth-hound or rig is a houndshark of the family Triakidae, found on the continental shelves and in estuaries around New Zealand. It is closely related to the gummy shark of Australia. Males can grow up to a length of 125 cm, while females can reach a length of 151 cm.
McMillan's catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks, in the order Carcharhiniformes. McMillan's catshark is a small, rare, and little-known deepwater shark that is endemic to New Zealand. It is found at depths of 985–1350m on the lower continental slope around New Zealand, on the West Norfolk Ridge, and off North Cape. It can grow to a length of 45 cm.
The false catshark or sofa shark is a species of ground shark in the family Pseudotriakidae, and the sole member of its genus. It has a worldwide distribution, and has most commonly been recorded close to the bottom over continental and insular slopes, at depths of 500–1,400 m (1,600–4,600 ft). Reaching 3.0 m (9.8 ft) in length, this heavy-bodied shark can be readily identified by its elongated, keel-like first dorsal fin. It has long, narrow eyes and a large mouth filled with numerous tiny teeth. It is usually dark brown in color, though a few are light gray.
The smooth lanternshark or slender lanternshark is a species of dogfish shark in the family Etmopteridae, found widely in the Atlantic and Pacific Oceans. It inhabits benthic environments at a depth of 274–1,000 m (899–3,281 ft), and pelagic environments at a depth of 0–708 m (0–2,323 ft). The smooth lanternshark forms a species group with the larger blurred lanternshark, both of which are distinguished from other members of their family by small, irregularly arranged dermal denticles with a truncated shape. This species has a slender, dark brown body with an indistinct black band on the sides over the pelvic fins, and reaches 50 cm (20 in) in length. This slow-growing, ovoviviparous shark feeds on smaller squid, fishes, and fish eggs. Smooth lanternsharks are often caught as bycatch in eastern Atlantic and Japanese commercial fisheries. The International Union for Conservation of Nature (IUCN) has evaluated this species as of Least Concern because of its wide distribution and limited threats.
The mouse catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks. It is common in the northeastern Atlantic Ocean from Iceland to Western Sahara. There is much taxonomic confusion regarding this species in Icelandic waters, where it may be confounded with another species of Galeus or Apristurus. Probably not exceeding 49 cm (19 in) long, the mouse catshark has a uniformly brown body and is characterized by large, rounded pelvic fins and crests of enlarged dermal denticles along both the dorsal and ventral caudal fin margins. In addition, in adult males the inner margins of the pelvic fins are merged into an "apron".
The white-bodied catshark is a catshark of the family Pentanchidae, the deepwater catsharks.
The hoary catshark is a shark of the family Pentanchidae, the deepwater catsharks. This species is found in the western central Atlantic in the Caribbean, at depths between 521 and 915 m. Its length is up to 45.5 cm (17.9 in). The reproduction of this catshark is oviparous.
The flaccid catshark is a shark of the family Pentanchidae. It is endemic to the waters around New Zealand.
The bulldog catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks/ This shark is 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 smalleye catshark is a species of shark beloning to the family Pentanchidae, the deepwater catsharks. This shark is found in the southeast Atlantic at depths between 700 and 2,000 m. It can grow up to 61 cm. The reproduction of this catshark is oviparous.
The ghost catshark is a species of shark belonging to the family Pentanchidae, the deepwater catsharks. This species is 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 southern lanternshark is a shark of the family Etmopteridae found in the southeast Pacific between latitudes 29°S and 59°S, at depths of between 220 and 1,460 m.
