THE COMMON SEA-CAT OR WOLF-FISH (sw. vanliga haf fatten). 
ANARRHICHAS LUPUS. 
Plate XII, fig. 2. 
Length of the head more than 1 / 5 of that of the body. Length of the pectoral fins more than 13 % of that of 
the body. The rout of vomerine teeth longer than the row on each palatine bone. End of the dorsal fin evenly 
rounded or (in young specimens) sloping gradually towards the base of the caudal fin ( the more or less hard , 
spinous rays which form this curve , from 10 to 13 in number, diminishing in length uniformly, or, in young 
specimens, with a slightly marked break). Frontal bones behind the eyes gathered at the top into a ridge. Colour- 
ing blackish gray, with more or less distinct black, transverse bands.

The Sea-cat attains a considerable size. Its length 
is usually between 4 and 7 dm., but specimens 12 dm. 
long are occasionally found. The body is elongated 
and more or less cylindrical; the sides strongly com- 
pressed, especially in the caudal region, and the belty 
pendent. The greatest depth of the body shows even 
relative increase with age: in specimens from 100 to 
400 mm. long it measures nearly 18 % of the length, 
and in specimens 11 dm. long about 22 %. The head 
is comparatively small: during early growth, from a 
length of 100 to about 600 mm., its length sinks from 
23 to about 20V 2 % of that of the body; but sub- 
sequently seems, even relatively, to increase, being 
about 22 % of the length of the body in specimens 
11 dm. long. The top of the head is rounded, the 
sides compressed, and the temples and cheeks tumid, 
thus showing the strength of the masticatory muscles. 
The snout is short and blunt, and the jaws project 
about equally. This circumstance, in conjunction with 
the long, conical front-teeth, gives the head a certain 
resemblance to that of a cat, and hence is derived the 
name of the species. The eyes are of moderate size 
and set high, close to the upper margin of the fore- 
head, and nearer to the snout than to the occiput. In 
specimens about 100 mm. long the diameter of the eye 
is about 1 / 3 of the length of the head, and twice the 
least depth of the tail; in specimens about 400 mm. 
long about equal to the latter; and in specimens 11 
dm. long the diameter of the eye is only slightly more 
than half the least depth of the tail. Thus, the changes 
a Sometimes 69 or even as many as 77, according to Nilsson. 
6 Generally from 43 to 46, according to Lilljeborg. 
c Sometimes 21, according to Bean.
