Cane Toad Facts, Pictures

Key Takeaways

Cane toads, native to Central and South America, were introduced to Australia in 1935 to control cane beetles, but the experiment failed as they didn't eat the beetles.
These toads have since become an invasive species, reproducing rapidly and threatening native Australian wildlife with their poisonous nature.
They have no natural predators in Australia and have caused significant declines in native animal populations, including snakes and lizards.

The cane toad is native to Central and South America, and an invasive species in Australia. It was introduced to Australia in 1935 to protect crops against cane beetles. The experiment failed because cane toads don't eat adult beetles and the larvae — which they would eat — live underground. The result is that the cane toad reproduced wildly and began to devastate native wildlife.

Although the cane toad has no natural enemies in Australia and is poisonous if ingested, so native predators that do occasionally feed on the giant amphibian end up dying themselves. Now several million strong (from an initial stock of 3,000), the cane toad continues to expand its range in Australia, pushing Australian snakes, lizards and other animals to the edge of extinction.

A large, stocky animal, the cane toad has dry, warty skin and ridges above its eyes. It inhabits grassland and woodland, only venturing to fresh water to breed.

Frequently Asked Questions

What methods are used to control cane toad populations in Australia?

Methods to control cane toad populations include physical removal, traps, fencing and biological controls like introducing natural predators or diseases that specifically target cane toads.

How do cane toads affect native Australian wildlife?

Cane toads secrete toxins that can kill predators such as snakes, lizards and birds that attempt to eat them, leading to significant declines in native species.
