A young cane toad. The cane toad in Australia is regarded as an exemplary case of an invasive species.Australia's relative isolation prior to European colonisation and the Industrial Revolution, both of which dramatically increased traffic and import of novel species, allowed development of a complex, interdepending system of ecology, but one which provided no natural predators for many of the ...
Currently, cane toads continue to extend their geographic range across tropical northern Australia, moving increasingly further west at an accelerated rate of 55 km per year. [ 22 ] At the invasion front, interactions occur between native species and the introduced toad, which lack shared evolutionary history. [ 5 ]
A beer-for-toads bounty has been publicised for cane toad control in the Northern Territory. [ 37 ] In 2002, a Victorian Fox Bounty Trial began to test the efficacy of fox bounties which have been in place intermittently since 1893 (only 30 years after introduction).
Cane toads were introduced to Australia in 1935 to control cane beetles and other pests but their population exploded and with no natural predators they have become a threat to Australian species ...
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.

About 230 of the 5,280 species of frog are native to Australia with 93% of them endemic. [1] [2] Compared with other continents, species diversity is low, and may be related to the climate of most of the Australian continent. [3] There are two known invasive amphibians, the cane toad and the smooth newt. [4] [5]
A cane toad was so big that it received the nickname, ‘Toadzilla.’ A native to Central and South America, see where it was discovered as an invasive species. This cane toad is called ...
Cane toads have become an invasive species in Australia since their introduction to the area in 1935; because of that, Australia is said to be currently facing an overpopulation of cane toads, which presents a problem for monitor lizards that mistake the poisonous amphibians for endemic toads native to Australia that make up the lizards' usual ...
