A Bullfrog Father Protects His Tadpoles

The little pool of water he spawns his young ones into, the water is beginning to dry up. The mother bullfrog leaves him behind to watch over the newly hatched tadpoles, he must show that he is a devoted father and dig a new channel to a larger water source to save his offspring. He must move quickly for each minute the sun rays are drying up the little pool and the tadpoles are clustered up together in the little water that remains. Finally, he succeeded in digging a channel to a larger water pool and he stands guard as the young tadpoles rush down the channel into the large pool of water and are saved.

The baritone call of the bullfrog is so deep and resonant, it resembles the mooing of a cow, hence its name. Only males emit this trademark "jug-o-rum" bellow, and their choruses can be heard during the day or night.

Size
The largest of all North American frogs, this giant can grow to a length of 8 inches or more and weigh up to 1.5 pounds. Even the tadpoles of this species can reach 6.75 inches in length.

Population Range
They are among the most wide-ranging of all North American amphibians, found in freshwater ponds, lakes, and marshes from Nova Scotia, Canada, throughout the continental United States, and as far south as Mexico and Cuba. They have even found their way to Europe, South America, and Asia.

Behaviour
Bullfrogs are typically green or grey-brown with brown spots and have easily identifiable circular eardrums, or tympanum, on either side of their heads.

Nocturnal predators, they will ambush and eat just about anything they can fit in their ample mouths, including insects, mice, fish, birds, and snakes. They sit quietly and wait for prey to pass by, then lunge with their powerful hind legs, mouths open wide.

Males are highly territorial and will aggressively guard their land.
