The Cane Toad

By Lily Simpson

Where the Cane Toad from...

Cane Toads are native to South and mainland Middle America. They were introduced to Australia from Hawaii in June 1935 by the Bureau of Sugar Experiment Stations.

Effects on Ecosystem...

In Australia, cane toads have no natural enemies. Their toxin can kill most native animals that normally eat frogs. They therefore pose a risk to both native fauna and pets such as cats and dogs.



The invasion of cane toads in Australia kills many large predators, when they try to eat large, toxic toads.


The decrease in numbers of predators benefits many smaller species, which increase in numbers after cane toads arrive in an area.
