The cane toad, Bufo marinus, was introduced to areas outside of its habitat of French Guiana to help control insect pests. Known for its large size and appetite, cane toads also feed on indigenous populations of frogs and snakes. There are two species of leopard frogs, the northern leopard frog and the southern leopard frog. Northern leopard frogs are usually more green in color, and the southern more brown in color. But frogs can change their color to their surroundings to help camouflage them from predators.
Leopard frogs are cold blooded animals.
Their body temperature changes with the seasons. As temperatures drop in late fall,they return to ponds, streams and rivers where their respiration and circulation decrease until they fall asleep into hibernation. They hibernate underwater in the mud. When temperatures warm, their body temperature returns to normal and they emerge from hibernation in early to mid spring. Unlike most frog species, female leopard frogs are able to sing, though not as loud as the males.
