Geography
The bullfrog is found naturally in the eastern half of North America, including eastern Canada, the eastern United States with the exception of the southernmost point of Florida as well as the northeastern part of Mexico. Bullfrogs also have been found in Cuba. They can be found anywhere there is freshwater.
Habitat
Tadpoles and adult bullfrogs live near bodies of water that are slow moving. They are usually found in streams, marshes, lakes and ponds, living along the muddy banks or water's edge. They also hide and use water plants such as long grass and lily pads as shelter.
Winter
The bullfrog hibernates in the winter in the mud at the bottom of ponds or rivers. What makes amphibians unique is that they can breathe under water as long as they can obtain oxygen through their skin while buried under the mud. When they hibernate, they also slow their heart rate and metabolism down significantly.
Introduced Habitats
The bullfrog is native to North America, but has been introduced all over the world. It is capable of thriving in Australia, Brazil, South Korea, Colombia and parts of Europe because of its ability to adapt to different environments with relatively the same climate. In these other locations the bullfrog is considered a nuisance and an invasive species because it eats so many of the native insects and other arthropods.
