Range & Habitat
They prefer open, damp, leaf littered fields where insect food is plentiful in their range from Patagonia to southern Texas. Introduced by man for pest control (with negative results) in Puerto Rico, Haiti, Hawaii and Australia.
This toad has two large parotid glands located behind each eye, which secrete a powerful bufo-toxin when the animal is disturbed. This toad has been introduced into the Caribbean Islands, South Florida (Key West and Stock Islands, Tampa Bay, Hillsborough, Dade and Broward counties), and Australia's east coast (East Queensland and Coastal New South Wales). It is considered the most introduced amphibian in the world. In their native range, they make a huge impact on insect-pest control.
Reproduction & Growth
The female produces a long string of eggs, about 7-10 feet long and contains as many as 35,000 eggs, which is wrapped around vegetation in the water. Tadpoles hatch in 2-7 days. Depending on the temperature, it takes about three months for a tadpole to develop into an adult. The marine toad is one of the largest species of toad, reaching a length of nine inches. The female is usually larger than the male.
In the Wild: Almost anything alive that is smaller than they are. In the Zoo: Insects and pinkie mice.
