More bad news from Australia's war on cane toads: Now they're killing freshwater crocs.

According to a blog on Nature's website, the invasive amphibians - which have recently hopped their way into the Northern Territory - are turning up in the stomachs of dead crocodiles.

A University of Sydney researcher told Cosmos magazine that freshwater crocodile populations in the Northern Territory have dropped by about 70 percent since the toads invaded their habitat. "When we first went in we counted about 700 crocodiles [in one area] and found no dead ones at all," biologist Michael Letnic told Cosmos. "But then we went back...after the cane toads had started moving through. This time we found less than 400 crocodiles...and, in the space of a week, we found over 30 dead."

Though cane toads seem to have no effect on the freshwater crocodile's brawnier, saltwater cousins, it may be time to expedite plans to enlist the Australian public in hunting down the pests.
