or stripes. Along the sides, just above the oHve yellow belly, there 

 is a row of yellow spots or bars or a broken yellow line which dis- 

 tinguishes the species from the equally common spotted salaman- 

 der, which has sides of a uniform slate color. The underside of the 

 Tiger Salamander is an olive yellow more or less blotched with olive. 

 The newly hatched larva is some 14 mm. long. From above, the 

 head appears almost circular. There are three gills to a side and they 

 have almost no filaments. There are no legs. The prominent dorsal 

 tail fin starts just behind the head. 





The color from above is yellow-green. There is a dark band 

 covering much of the head and back. Along the back there are 

 about six pairs of dark spots. There is another dark band low on 

 either side, with a light, rather spotted band. In side view this 

 species is distinctly banded. 



The mature larva, which is about 100 mm. long, has a shovel- 

 shaped head and large, profusely filamented gills. The body is 

 tapering. A wide fin runs from back of the head around the tail 

 to the vent. At this stage the larva is dark brown to black above 

 and creamy silvery beneath, except on the throat, which is bluish. 



Size. Usually between 175 and 225 mm. The male tends to be 

 distinctly larger. 



Habitat. The adult lives in deep burrows beneath old logs, in 

 piles of decaying vegetation or manure, in drain pipes, and even in
