The primary mechanism of impact cane toads have on Australian ecosystems is through poisoning of native species. [2] The parotoid gland on either side of the head of a cane toad produces a secretion containing bufadienolides that is toxic to most animals.

The University of Florida recommends euthanizing cane toads by rubbing or spraying 20 percent benzocaine toothache gel or sunburn spray (not 5 percent lidocaine) on the toad. In a few minutes, it ...
The story begins with the toads in full form 15 million years ago, and fast-forwards to the 1935 introduction of 102 cane toads to Australia in an ill-conceived attempt to take on the cane beetle devastating sugarcane crops. The toads' proliferation got out of hand, and they became a seriously invasive species, marching across Australia ...
