What is the population of cane toads?
Scientists estimate that there are well over 200 million of the amphibians in Australia. They have become so abundant, says DeVore, that they face more evolutionary pressure from each other, as they compete for resources, than from anything else in Australia.

How are they trying to reduce the cane toad population?
Scientists have been trying to control the spread of cane toads for years; recent experiments have shown progress. For example, Georgia Ward-Fear and colleagues used open cans of cat food to lure native meat ants to the shores of ponds inhabited by baby cane toads.
