Bullfrogs (Rana catesbeiana) are native to the northeastern part of North America and are some of the most damaging invasive species. Many cultures around the world eat frog as a delicacy, so bullfrogs were gathered up and sold around the world. However, some of the species were introduced into countries around the world. Currently, they have become established in over fifteen countries as invasive species (Save The Frogs! et al. 2013). Many sources say that the initial spread of this invasive species began at the end of the 1800's when bullfrogs were shipped to California to fill hungry loggers appetite for frog legs. The frogs competed with the other native species with the supply of natural resources while also consuming and exploiting the native amphibian species as well. Worldwide Rana catesbeiana has driven over one-hundred native species of frogs to extinction (Save The Frogs! et al. 2013). This is a huge impact on amphibian wildlife worldwide because there are about 4,800 species of frogs. Over the past hundred years the bullfrog has wiped out over 2% of the world's species of frogs. Studies have shown one of the reasons bullfrogs will cripple Arizonian ecosystems and the native amphibian species directly is because a female bullfrog’s physiology…
