SEA WOLF. 
The Sea Wolf is a very ferocious animal, 
and is often caught at Heligoland, an island 
a short distance from the mouth of the Elbe. 
Its head is bigger, and somewhat rounder 
than that of the shark. The sides, back, 
and fins, are of a blackish or bluish colour \ 
the belly white. It is about three feet in 
length, and its whole skin is smooth and 
slippery, having no scales. It has a double 
row of sharp and round teeth, ten or twelve 
in each row, both in the upper and lower 
jaw. They seize almost every thing that 
'comes within their reach, and devour not 
only fish, but even lobsters, crabs, &c. It is 
said that it will sometimes fasten on an 
anchor with its teeth, and leave the print of 
them behind it.
