mixtures, the southern leopard frog can also be recognized by its long, 
gracefully pointed head and a circular white spot at the center of the ear. 
Dark green or brown spots cover the bullet-shaped body. 
PICKEREL FROG 
The agile American pickerel frog does not resemble the pickerel, but is 
used as a bait to lure that tasty fish. An unpleasant skin secretion prevents 
the frog from being eaten by man, and it appears to be poisonous to other 
frogs, for when other varieties are confined with it, they usually die. This 
frog spends most of its time on land and is often confused with the leopard 
frog because of its spots, which, however, are square and without yellow 
margins. The young pickerel frog sheds its skin even before the stub of 
its tadpole’s tail has entirely disappeared. In the sunlight the young are 
a lustrous bronze color, but when emerging from the water, they can 
scarcely be distinguished from the mud. 
WOOD FROG 
The eastern wood frog is unique in its ability to turn in mid-air, so that 
on landing from its long leap, it faces its enemy. Sometimes each of this 
frog’s eggs is surrounded by a green jelly, composed of microscopic plants 
which feed on the carbon dioxide given off by the embryo and in turn 
supply it with oxygen. Of all American frogs this is the most terrestrial. 
Its excellent protective coloration makes it hard to locate, but once detected 
it is easily identified by its dark brown or black cheek patches with a yellow- 
gold line running along the sides of the upper jaw to the shoulder. 
GREEN FROG 
Visitors to American ponds are often surprised by green frogs which jump 
into the water, seemingly from nowhere, uttering a deep jurg as they land. 
These familiar, metallic-green frogs are almost entirely aquatic. They shed 
their skin four to five times a year, and if the process takes place on land, 
they swallow the skin.
