The American Bullfrog

Family Name
Ranidae
Species
L. catesbeianus

The American bullfrog (Lithobates catesbeianus or Rana catesbeiana) has a large robust body that can reach 20 centimeters in length. They are green or brown in colour and have yellow or pale cream to white throats. American bullfrogs displace native frogs in habitats they invade by outcompeting and depleting the food sources of native frogs. Their colonization of lakes is followed by decline in the native red-legged frog and pacific chorus frog populations.
