Cane toads are reportedly responsible for wiping out some populations of dwarf crocodiles in Northern Australia.
In Northern Australia, it’s a showdown - toads versus crocodiles.
Cane toads are reportedly responsible for wiping out some populations of dwarf crocodiles in the area. Charles Darwin University researchers have been looking into the impact on the tiny crocodile species that rarely reach over 3 feet in length. They are found only in freshwater.
The crocs' population growth is stunted due to lack of food in the Victoria and Bullo rivers. Cane toads were introduced as an addition to their diet, however they’ve proven to be a deadly food source.
The dwarf crocodiles are poisoned after consuming the cane toads as they ingest their prey’s bufotoxins.
Dr. Adam Britton is one of the researchers studying the phenomenon.
He stated “We really don't know whether these cane toads are going to wipe them out completely. We know that the initial impact of the toads is very severe.”
The research team did uncover potential evidence that suggests dwarf crocodile populations could be saved if they adapt their behavior and eat only the back legs of the toxic toads.
