Bullfrog
Bullfrogs are prey to various birds like herons, and their life in the wild is much less than in captivity. One captive bullfrog lived almost 16 years. The name "bullfrog" was given because males roar when mating with a female. Bullfrogs can be kept as pets. Captive bullfrogs are given rodents, small fish, crickets, worms, and fruit flies as food and treats. Pet owners may add supplements on the frogs food for health. Bullfrogs can host many viruses, bacteria and parasites. They were blamed for an intraerythrocytic virus outbreak in Canada in 1997. Bullfrogs are the cause of the chytrid fungus spreading into Arizona. The fungus is one of the main reasons that there are fewer amphibians.
