MAMMALIA OF THE SEA. 87 



LESSON XII. 



MAMMALIA OP THE SEA. 



SEVERAL of the mammalia live entirely in the 

 sea. Amongst these are various kinds of whale, 

 the narwhal, and the dolphin. These animals, 

 though living in water like fish, and having the 

 same habits in general, nourish their young in the 

 same manner as the other mammalia. 



The whale is the largest of all animals, and 

 grows to a vast size, sometimes measuring eighty 

 or ninety feet in length, nearly as many in circum- 

 ference, and weighing from two to three hundred 

 thousand pounds. The mouth of the whale is very 

 large, and the tongue fourteen or fifteen feet long, 

 and seven or eight feet wide.
