Another species is Halicore australis, found numerous on the coasts of 

 Australia. It is stated to be bluish on the back, with a white breast and 

 belly. It grows to 18 or 20 feet in length. The oil obtained from the 

 fat is highly prized. 



Other herbivorous Cetaoea are the Manatis, Manatus, Cuvier, with two 

 or three species, from the mouths of rivers in Africa and America. They 

 have vestiges of nails on their swimming paws, and the adults have no 

 incisors.
