棘鯊科 (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).

Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 200 - ? cm
Max length : 310 cm TL 雄魚/尚未辨別雌雄; (Ref. 247); common length : 200 cm TL 雄魚/尚未辨別雌雄; (Ref. 26999)
背棘 (總數): 0; 背的軟條 (總數): 0; 臀棘 0; 臀鰭軟條: 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).
荊棘鯊魚 棘鯊〔Echinorhinus brucus〕 有在身體上的像刺一樣的細齒那是非常大的 (單一細齒達到大約在基部的直徑中的 15 mm 當成魚時), 稀疏的不規則地分佈了與像刺一樣的底邊平滑的, 一些基底融合成複合的碟了。 背面暗紫灰色褐色的有白色的細齒，腹面灰白; 側面與背面可能有深色斑點。 牙齒數目 20-26/21-26.與棘鯊科的另一個成員相較, 它有一個相當短的吻與矮胖的身體; 二個小的無棘背鰭, 靠攏在一起, 向身體後部而且在腹鰭起點後面開始。 沒有在尾鰭上的臀鰭與接近端位的凹槽。 小的呼吸孔, 非常短的唇溝而且一樣牙齒在雙顎, 具有一個中央的斜角刀狀尖端在兩邊 (不存在於稚魚) 上多達 3 cusplets.(參考文獻 247,6871,5578)
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).
一隻稀有的 (參考文獻 26346) ﹐大的﹐和緩動性又深水的鯊魚發現於大陸棚與島嶼棚與上層斜坡了。 (參考文獻 247) 有時發現於淺水區。 (參考文獻 247) 吃較小的鯊魚，硬骨魚類與螃蟹。 (參考文獻 247) 卵胎生的 (參考文獻 205), 具有 15-26 幼魚在一胎.(26346) 從未記錄到攻擊人。 有時被岸釣者釣獲.(參考文獻 5578) 加工成魚粉了。 可能是在非洲南部中被用於傳統的藥。 (參考文獻 5578)
