The dog sharks are found most commonly in temperate regions. They 

 seem to be more common in the Atlantic Ocean than in any other body 

 of water. They live near shore and are sometimes caught in nets for the 

 oil which may be extracted from them. They are regarded as destructive 

 to herring and to other food fishes. 



Three species of this family are known to occur in Hawaiian waters.

The dogfish shark is a small shark, uniformly brownish or dark slate 

 gray or blue in color above and lighter beneath. Most individuals are less 

 than three feet in length, although they may possibly exceed this size. 



The flesh of this fish is edible. Barnhart reports that it is an edible 

 fish in which the flesh is "fine, smooth, and white with an excellent flavor." 



A great many of these fishes are caught each year and preserved for 

 biological supply houses to be used by students of zoology. 



The dogfish shark is widely distributed in the Pacific Ocean. It is 

 common about Hawaii and is abundant along the coast of California. 

 Curiously enough, it is reported to be abundant in the shallower waters 

 of northern California and is caught only in deep water off southern 

 California.
