Rising Temperatures Impact Crocodile Behavior: Australian Crocodiles Struggle to Adapt to Climate Change

Climate change is increasingly affecting wildlife, including crocodiles. A recent study reveals that rising global temperatures are causing an increase in crocodile body temperatures, altering their behavior. Saltwater crocodiles (Crocodylus porosus) in Australia are finding it challenging to adapt to the escalating heat. As cold-blooded animals, their body temperature depends on the environment. They typically bask in the sun to warm up or seek shade and water to cool down. The study, published in *Current Biology* (Feb 12, 2024), monitored 203 crocodiles in Queensland between 2008 and 2023. Researchers tracked the crocodiles' temperatures and diving habits. The results showed that the crocodiles' highest body temperatures rose by approximately 0.55 degrees Celsius. 135 crocodiles recorded body temperatures above 32 degrees Celsius. Rising temperatures force crocodiles to spend more time cooling down, reducing their hunting time and potentially impacting their long-term survival. This shift could affect their ability to hunt, breed, and migrate, ultimately impacting their overall health.
