“ They are the special enemies of the fisherman, injuring his nets, removing the hooks from his lines, and spoiling his fish for the market by biting pieces out of them as they hang on his lines. They are however eaten, both fresh and salted, by fishermen, especially on the west coast of England, and they are sold regularly in the French markets. ”

“ This species is viviparous, the female producing five to nine young at a birth; the young when born are 9 to 10 in. long and quite similar to the parents in all respects except size. It is gregarious, and is abundant at all seasons everywhere on the British coasts. ”

“ They keep near the sea bottom, feeding chiefly on the smaller fishes and Crustacea, and causing great annoyance to the fishermen by the readiness with which they take bait. They differ from the majority of sharks, and resemble the rays in being oviparous. ”
