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 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 genome has been sequenced and certain Australian academics believe this will help in understanding how the toad can quickly evolve to adapt to new environments, the workings of its infamous toxin, and hopefully provide new options for halting this species' march across Australia and other places it has spread as an invasive pest.
Australian park rangers believe they have stumbled upon a record-breaking giant toad deep in a rainforest. Dubbed "Toadzilla", the cane toad, an invasive species that poses a threat to Australia's ...
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 ...

Native to the Mediterranean regions, more than one species of white snail is now quite common in Kadina and elsewhere in South Australia. This image shows many Theba pisana , and a number of smaller and more pointed Cochlicella acuta aestivating on a fence post.
Though toads and frogs are a part of their diet, cane toads are poisonous to Mitchell's water monitor and many other water monitor species. [17] 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 ...
