Since cane toads were introduced to Australia in 1935, they have colonized 1.2 million square kilometres of that country . They might just be getting started, says ecologist Mark Urban of the University of California, Santa Barbara in Proceedings of the Royal Society B
"The untapped habitat lies in temperate, coastal regions of western and southern Australia - around Perth and Adelaide, for example. That may seem a long way from where they are now, but the toads could get there,...They have an uncanny ability to hide out in trucks and airplanes."
They have also been evolving longer , stronger legs since their arrival , witness this buffed two pound specimen of Bufo Marinus caught, appropriately enough, in Darwin
