Crocodiles prefer aquatic meals after toxic toad invasion

Still Waters

Posted (IP: Staff) ·

To avoid eating their final meal, Australian crocodiles may wash their mouths out and try a different diet instead.

Along with many other animals of northern Australia, the reptiles' habitats are being overrun by toxic cane toads, an invasive species that was introduced in the 1930s. Eating just one of these amphibians is fatal to the crocodiles.

To try and minimise this possibility, crocodiles from toad-filled areas seem to have adapted to eat their prey in the water, where they can flush out the toad's poison if they start to eat the amphibians by accident.

They also become seemingly choosier about their food, with crocodiles which are used to the toads being more likely to reject them in favour of another meal.
