The monk-fish, angel-fish, fiddle-fish, or bullhead shark, all of which 
names are more or less appropriate, is one of the strangest in a])pearance 
of living fishes. Its circular head, constricted neck, and winglike 
pectoral fins are diagnostic. It is one of those forms intermediate between 
the normal shark and the flattened ra\- or skate. Its skin is said to ha\-e 
been much used by the ancients. 
Squatina is widely distributed in warm seas, on both sides of the 
Atlantic and also along our Pacific shores. It occurs s])aringl\ on our 
eastern coast northward to Cape Cod. Pebbles, fishes, and the opercula 
of wdielks have been foiuid within its .stomach. It is said to produce 
about twenty young at a l^irth. It occurs occasionally in summer in the 
bavs along the south shore of Long Island.
