BRANCH VERTEBRATA. 



Skull ol' a Carnivorous Animal. 



like the Walrus and some of the Seals, are timid and 

 ^ ,,01. retiring, falling an easy prey 



to their enemies. 



Among their anatomical pe- 

 culiarities are (1), their denti- 

 tion, marked by long, sharp, 

 canine teeth, the last molar 

 on each side, above and below, 

 being larger and sharper than the others, used for crush- 

 ing bones, and known as 

 the "carnivorous tooth"; 

 and (2), their feet, which 

 are, in the more typical 

 forms, provided with toes 

 armed with sharp claws. 

 These anatomical pecul- 

 iarities afford the basis 

 of a classification.
