Crocodiles Might Not be Climate-Change Proof After All
Even saltwater crocodiles aren’t safe from climate change.
The species is considered one of the most resilient in Australia, but new research shows that it spends less time underwater when temperatures increase, and that could put its survival in jeopardy as heat records continue to be broken.
Crocodiles dive for food, protection, socializing, and even a catnap. They can typically stay underwater for 10- to 15-minute periods and up to 30 minutes if they are trying to hide from a threat. On average, a crocodile spends around 11 hours a day submerged.
To see how climate change would affect Australia’s saltwater crocs, researchers at the University of Queensland studied juvenile crocodiles in three pools heated to different temperatures.
