Hot crocs show impacts of a warming climate

Crocodiles in northern Australia are changing their behavior due to increasing body temperatures caused by climate change, spending more time near their critical thermal limit of 32-33°C, according to research led by The University of Queensland.
Since 2008, the peak body temperatures of crocodiles in the study have risen by 0.5°C, with a median increase of 0.11°C, as reported by the Northern Australia Climate Program.
High body temperatures negatively affect crocodile diving and swimming performance, as noted by Professor Craig Franklin, impacting their ability to hunt and reproduce.
Researchers suggest that ongoing climate pressures may force saltwater crocodiles to cool more frequently or migrate southward to higher latitudes, as explained by Kaitlin Barham.

Warming climate making crocodiles hotter with unknown effect

Andrea the crocodile. Credit: Australia Zoo Crocodiles in northern Australia are altering their behaviour to try to keep cool as they experience increasingly stressful temperature extremes driven by climate change. New research has revealed that saltwater crocodiles (Crocodylus porosus) are spending more time at or close to their critical thermal limit of 32-33°C, diving less and cooling themselves off more. “As ectotherms crocodiles can’t regul…
