Amphibians The Frog 
sunshine. He is an omnivorous eater of living 
creatures, and has small teeth on his upper jaw. He 
feeds upon minnows, crayfish and tadpoles, and any- 
thing else that he can entice into his capacious mouth. 
Frog’s eggs are laid in masses of gelatine-like sub- 
stance, but they are never laid in strings, like the 
toad’s. The frog tadpoles require a longer time to 
mature than do toad tadpoles, usually about four 
months. However, the great tadpoles of the bull- 
frog do not attain frogship until the second, and 
sometimes the third season. 
HOUSING, FOOD AND CARE 
An aquarium built as described for the toads does 
as well for frogs. Food should be given but once a 
week, but this meal should be a large one. Frogs 
like all kinds of insects, and meal worms may be 
given during the season when other insects are not 
available. The bullfrogs may be fed minnows, 
earthworms, and even mice. All frogs are fond of 
raw liver and this may be used constantly for food 
during the winter. 
The water in the aquarium should be completely 
changed each week, the day after feeding. 
Frog tadpoles may be kept in an aquarium similar 
to that described for the toad tadpoles. The young 
ones are especially fond of the tulip leaves prepared 
as described.
