NEWTS AND SALAMANDERS 



Although Newts ana Salamanders are nearly related to the 

 Frogs and Toads, there is a marked difference in their adult forms. 

 The latter are then, as we have seen, without tails, while the

former possess tails of great development which serve the purpose 

 of propellers in the water. 



A few of the newts and salamanders have no hind-legs, and 

 one group has no legs at all. These form the order Apoda to 

 which we have referred above, apoda meaning simply without feet. 



The newts and salamanders are more devoted to an aquatic 

 life than the frogs and toads; but they are almost all lung- 

 breathers, and so have to come to the surface of the water for 

 air.
