PLANT-EATING BIRDS, REPTILES, AMPHIBIANS, FISHES 195 



some of the Sea- Breams {Sparidce) and a few species of Carp 

 ( CyprinidcB). 



Certain Sea- Breams (species of Haplodactylus), which inhabit 

 the cooler parts of the South Pacific, live upon sea-weed, and 

 their jaws possess flattened teeth armed with projecting points, 

 capable of dealing with this sort of food. 



The Beaked Carps (species of Chondrostind), that live in 

 some of the rivers of Europe and Western Asia, browse upon 

 the green thread-like algae which grow on stones, and the edge 

 of the lower jaw in these fishes is provided with a sharp cutting 

 edge, well adapted for mowing down this slippery vegetable 

 growth.
