Northeast Atlantic: Norway and British Isles south to Senegal, including the Mediterranean. Possibly Côte d'Ivoire. Some populational differences exist between Catulus duhameli (a name for the Mediterranean canicula based on size) and this species which may eventually be expressed as subspecies. The only reported observation of this species in Crimean waters was in 1937, which is possibly erroneous (Ref. 897).

生物学特性     字汇 (例如 epibenthic)

Most common catshark in coastal waters of Europe (Ref. 32804). Inhabits continental shelves and uppermost slopes. Found on sandy, coralline, algal, gravel or muddy bottoms. Occurs mainly between 10-100 m depth in the northeast Atlantic and up to 400 m depth in the Mediterranean Sea (Ref. 88187) and from 288-780 m in the eastern Ionian Sea (Ref. 56504). They sometimes occur in midwater. Nocturnal species, males resting on substrate and females hiding in shallow (0.5-1.5 m depth) caves and crevices during the day (Ref. 88835). Feed on a variety of benthic invertebrates, including mollusks, crustaceans, small cephalopods, polychaete worms, and small bony fishes (Ref. 244, 11889). Males have been found to forage in shallow prey-rich areas with soft sediment or areas covered with filamentous algae (Ref. 88836). Oviparous, with a single egg laid per oviduct at a time. Detect weak electric fields generated by other organisms (e.g. potential prey) (Ref. 10311). Utilized fresh and dried-salted for human consumption, also for oil and fishmeal.

Oviparous, laying paired eggs (one per oviduct) in shallow subtidal areas, although some egg cases have been found in the deeper part of intertidal zones (Ref. 244). Embryos feed solely on yolk (Ref. 50449). The egg cases are anchored to macroalgae, sea grass or sessile erect invertebrates such as poriferans, bryozoans and hydroids (Ref. 32804, 58137). The capsules have tendrils at each corner used for anchorage purposes. Egg capsule size varies according to locality and female size (Ref. 244) and ranges between 4.9-7.0 cm length and 1.5-3.0 cm width (Ref. 88837). Egg cases may be deposited throughout the year, peaking in June and July (Ref. 32804). Recent studies estimate fecundity of females from the northeast Atlantic to be at around 29-62 pups (Ref. 32804). Fully formed pups hatch after 5-11 months, depending on water temperature (Ref. 244, 32804). Newly hatched pups are about 8-10 cm in length (Ref. 78469). 東北大西洋: 挪威與不列顛群島南至塞內加爾, 包括地中海。 可能地象牙海岸。 一些族群的差異在 Catulus duhameli(一個名稱對於以大小為依據的地中海 canicula) 與這種之間存在那可能最後被表示成亞種。 在克里米亞半島的水域的這種的唯一被報告的觀察在 1937 年, 是可能錯誤.(參考文獻 897)
