American Bullfrog Introduction
The American bullfrog is a semi-aquatic frog, primarily know for the loud call sounds it makes. 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. 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. 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. Bullfrogs are typically green or gray-brown with brown spots and have easily identifiable circular eardrums, or tympanum, on either side of their heads.
