Elasmobranchii 板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) > Squatiniformes (Angel sharks) 琵琶鮫目 (Angel sharks) > Squatinidae (Angel sharks) 琵琶鮫科(Angel sharks) (Angel sharks)
Etymology: Squatina: Latin for skate, which angel sharks superficially resemble, presumably tautonymous with Squalus squatina Linnaeus 1758 (no species mentioned) (See ETYFish); squatina: Latin for skate, which angel sharks superficially resemble (See ETYFish).
More on author: Linnaeus.

East Atlantic. Its range and abundance is declining severely throughout its range. There is a proposed legal protection in Britain (Ref. 58085). The European Council Regulations 43/2009, 23/2010, 57/2011, 44/2012, 40/2013, 43/2014, 2015/104 and 2016/72 prohibit to fish for, to retain on board, to tranship and to land this species in all waters from the European Community (F. Osaer, pers.comm. 04/2016).

A benthic species that occurs inshore, on coasts and along the continental shelf; may enter estuaries (Ref. 247, 58085). Found mainly on sand or mud bottoms; sluggish by day, lying buried with eyes protruding. Also utilizes areas with macroalgae, kelp or rocks (Ref. 88920). Nocturnal species, swims off bottom at night. Feeds mainly on flatfishes and other benthic fishes, but also on skates, crustaceans and molluscs, with one record of swallowed cormorant (Ref. 247, 28070). Moves to deeper waters during winter, returning to the shallower depths in the spring (Ref. 88187), moving northwards in summer. Ovoviviparous (Ref. 50449, 107715). Females generally grow larger than males (Ref. 58137, 107710, 107713, 107715). Detects weak electric fields generated by other organisms (e.g. potential prey) (Ref. 10311). The marine leech Stibarobdella macrothela is a common parasite (Ref. 107712) and the isopod Aegapheles deshaysiana a common micropredator (Ref. 107714) for this shark species in the Canary Islands. Utilized fresh and dried salted for human consumption, and possibly for oil and fishmeal (Ref. 247). Reaches 250 cm (Ref. 35388).

生命周期和交配行为 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Ovoviviparous, produce 7-25 pups/litter (Ref. 58085), 13.0 +/- 1.9 pups in the Canary Is (Ref. 107713) with litter number increasing with female size. Gestation period lasts for 8-10 months (born Dec-Feb in Mediterranean, July in England) (Ref. 58085), and +/- 6 months in the Canary Is (Ref. 107713). Size at birth ranges from 24-30 cm TL (Ref. 58085). Embryos feed solely on yolk (Ref. 50449). Full term embryos weighed 189-200 g; no egg capsules found around ova or embryos (Ref. 107715). A biannual reproductive cycle is likely the case for this species (Ref. 32746), triannual cycle in the Canary Is (Ref. 107713).東北大西洋: 挪威南部，瑞典與雪特蘭群島到摩洛哥與撒哈拉西方部, 包括加納利群島與地中海。
