SQUALIDE, a family of fishes of the section Chondropterygii, which includes the various species of sharks. The shark's body is elongated, tapering gradually from the head to the tail, or but little dilated in the middle. The male shaiks are smaller, and differ externally from the females in posses.-ing two elongated appendages, one of which is attached to the hinder edge of each of the ventral fins, the uses of whivh are not known. Some species of sharks bring forth their young alive, whilst others are enclosed in oblong semi transparent horny eases, at each extremity of which are two long tendrils. These cases are frequently found on the sea-shore, and are called sea-purses, mermaids' purses, etc. They are de posited by the parent shark near the shore in the winter months. The convoluted tendrils, hang ing to sea-weed or other fixed bodies, prevent the cases being washed away into deep water. Two elongated fissures, one at each end, allow the admission of sea-water ; and the young fish ultimately escapes by an opening at the end near which the head is situated. For a short time
the young shark continues to be nourished by the vitelline fluid contained in the capsule attached fl. Brine.
