PLANT-EATING BIRDS, REPTILES, AMPHIBIANS, FISHES 195 



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

 (Cyprinida). 



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.
