Scyliorhinidae catsharks may be distinguished by their elongated, cat-like eyes and two small dorsal fins set far back. Most species are fairly small, growing no longer than 80 cm (31 in); a few, such as the nursehound (Scyliorhinus stellaris) can reach 1.6 m (5.2 ft) in length.
The shark occupies depths of 36 to 750 meters (118–2,461 ft); in the northern part of its range it is mainly found between 36 and 230 meters (118–755 ft) and in the southern areas generally deeper than 460 meters (1,510 ft). [5]
The eggs are contained in tough capsules around 4 cm (1.6 in) long and 1.5 cm (0.59 in) across; the capsule has thick tendrils at the corners that allow it to be secured to the sea floor. The female retains the eggs internally until the embryos are substantially developed, measuring at least 4.3 cm (1.7 in) long.
The longhead catshark or smoothbelly catshark (Apristurus longicephalus) is a species of shark, family Pentanchidae, the deepwater catsharks. This shark has a patchy distribution in the Indo-Pacific from Mozambique to southern Japan to northern Australia. It is found in water between 500 and 1,140 m (1,640 and 3,740 ft) deep.
Sharks portal; The ghost catshark (Apristurus manis) 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 (2,000 and 6,200 ft).
The cloudy catshark reaches 50 cm (20 in) long and has a thin, deep, and firm body. The narrow head makes up slightly under one-sixth of the total length, and is two-thirds as wide as it is long. The snout is short and rounded. The large nostrils are preceded by small, triangular flaps of skin that do not reach the wide mouth.
The eggs are enclosed within tough, flask-shaped capsules around 4.9–5.1 cm (1.9–2.0 in) long, 1.2–1.4 cm (0.47–0.55 in) across the top, and 1.6 cm (0.63 in) across the bottom. The rounded upper corners of the capsule bear coiled tendrils. [5] The spawning grounds of this shark may be located in very rough terrain. [1]
