Rana - from the Latin word meaning frog
catesbeiana - named after the German naturalist, Mark Catesby
Large and aggressive bully
Its common name derives from the fact that its call sounds like a bellowing bull. This species is not only the largest frog in Canada, but it is bolder and more aggressive than other frogs. It often eats other frogs that stray into its breeding area. In recent years, bullfrog populations have decreased because of pollution, habitat loss, and over-harvesting for human consumption.
