CASE STUDY: CANE TOADS
... There are no specific predators of cane toads in Australia. The ability of cane toads to rapidly increase in number and expand into new areas and eat a large volume and variety of prey means they could displace many native species. Toads prey on native animals especially insects and other invertebra ...
