The spread of the cane toads in Australia from 1940 to 1980 in five-year intervals. The long-term effects of toads on the Australian environment are difficult to determine, but some effects include "the depletion of native species that die eating cane toads; the poisoning of pets and humans; depletion of native fauna preyed on by cane toads; and reduced prey populations for native insectivores ...
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. [2] [5] This chemical defence does not exist in any native Australian anuran. [6]
The cane toad is estimated to have a critical thermal maximum of 40–42 °C (104–108 °F) and a minimum of around 10–15 °C (50–59 °F). [43] The ranges can change due to adaptation to the local environment. [44] Cane toads from some populations can adjust their thermal tolerance within a few hours of encountering low temperatures.

Gray’s colleague, senior park ranger Barry Nolan, told Reuters the animal was euthanised due to its “ecological impact” — the usual fate for the toads across Australia. Cane toads were ...
Large, toxic and voracious cane toads are being collected by hand in Taiwan in a bid to protect pets, wild animals and even humans on the island. Large, toxic and voracious cane toads are being ...
On the edge of a dark, suburban park in Brisbane, teams of volunteer toad-catchers gather around Gary King as he shoves another squirming specimen into a cooler box. This warty, toxic pest ...
Cane Toads: An Unnatural History is a 1988 documentary film about the introduction of cane toads to Australia. Cane toads were introduced to Australia with the aim of controlling a sugar cane pest, the cane beetle, but they over-multiplied and became a serious problem in the Australian ecosystem.
More doubtful biological controls were the cane toad, which was introduced to control the sugar cane destroying cane beetle; instead the cane toad ate anything and everything else—the beetle was not its preferred food source given choice. The cane toad in Australia has become the biological control that is most infamous for having been a ...
