Echinorhinidae (Bramble sharks)
Etymology: Echinorhinus: echinos (Gr.), spiny or sea urchin, referring to thorn-like denticles (brambles) on body; rhinus, an ancient name for sharks, from rhine (Gr.), rasp, alluding to a shark’s jagged, rasp-like skin (See ETYFish); brucus: Latin for caterpillar, presumably referring to “Chenille” or “Chenille de mer” (Sea Caterpillar), local names for this shark along the Atlantic Coast of France (type locality) in the 18th century (See ETYFish).

Espinhos dorsais (total) : 0; Espinhos anais: 0. The bramble shark Echinorhinus brucus has thorn-like denticles on body which are very large (single denticles up to about 15mm in basal diameter in adults), sparse irregularly distributed and thorn-like with smooth basal margins, some bases fused into compound plates. Dorsal surface dark purplish-grey to brown with white denticles, ventral surface paler; sides and back may have dark spots. Tooth count 20-26/21-26.As with the other member of the family Echinorhinidae, it has a relatively short snout and stout body; two small spineless dorsal fins, close together, towards posterior part of body and originating behind pelvic fin origin. No anal fin and subterminal notch on caudal fin. Small spiracles, very short labial furrows and teeth on both jaws alike, with a central oblique bladelike cusps with up to 3 cusplets on each side (absent in juveniles) (Ref. 247, 6871, 5578).
Body shape (shape guide): elongated.
A rare (Ref. 26346), large, sluggish, deepwater shark found on continental and insular shelves and upper slopes (Ref. 247). Sometimes found in shallow water (Ref. 247). Feeds on smaller sharks, bony fishes, and crabs (Ref. 247). Ovoviviparous (Ref. 205), with 15-26 young in a litter (26346). Never recorded as attacking people. Sometimes hooked by shore anglers (Ref. 5578). Processed into fishmeal. May be used in traditional medicine in southern Africa (Ref. 5578).
Ovoviviparous. 15 to 26 young in a litter (Ref. 26346). Size at birth between 29 and 90 cm. Distinct pairing with embrace (Ref. 205). Size at maturity unknown but adult males of 150 cm and adult females of 213 cm have been reported (Ref. 6871).
