Why are cane toads in Australia considered an invasive species rather than simply nonnative?

A.) They are destructive to native species and have no natural predators.

B.) They reproduce more quickly than native species.

C.) They have venom glands.

D.) Large adult specimens are able to hunt snakes.

The correct answer is A.) They are destructive to native species and have no natural predators.

Because of having no natural enemies, there are no predators that hunt them and keep them in line, which leads to overpopulation of the species. They don't die quickly which creates many cane toads that feast on native species without being stopped.
