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 ...
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.

This makes the rakali one of the very few natural defenses in the fight to contain the cane toad’s population boom and spreading westward. Since the early twentieth century (when cane toads were blindly introduced to supposedly control sugar cane beetles on farms), the toads in Australia have multiplied from an initial 100 animals to as many ...
