in creeping upon the ground, and in carrying their little ones; 

 these fins have been compared to hands, and hence is derived the 

 name by which they are distinguished. They inhabit the warm 

 regions of the Atlantic Ocean, near the mouths of rivers, which they 

 sometimes ascend to a considerable distance. They live in flocks, 

 often land, and are readily approached. They display the greatest 

 attachment to their companions. The Manati are sometimes fifteen 

 or even twenty feet in length ; their flesh is eaten and esteemed a 

 luxury. 



The Dugongs (Halicore f) differ from the Manati by having their 

 tail-fin shaped like a crescent, and pointed tusks that protrude 

 from the upper jaw. They inhabit the shores of the Indian Ocean.
