The shark is born at a length of 0.8 to1 ft [24 to 30 cm]. Females mature at 4.1 to 5.5 ft [126 to167 cm], and males reach a maximum length of 6 to 7.3 ft [183 to 224 cm].
The shark prefers mud and sand bottoms inshore 16.4 ft [5 m] on coasts and estuaries up to over 492.1 [150 m] on the continental shelf.
Northeast Atlantic: historically from Norway to Mauritania, Canary Islands, Mediterranean and Black Sea. They have now vanished from some of these areas.
Prey – Feeds mainly on flatfishes, skates, crustaceans, and mollusks. Reproduction – 7-25 pups per litter, increasing with female size. Their gestation is 8-10 months, born December-February in the Mediterranean; July in England.
