Climate change may be pushing crocodiles to their limit, a new study finds.
In Australia, estuarine crocodiles (Crocodylus porosus) are struggling due to global warming. Like most reptiles, crocodiles are ectothermic (cold-blooded), which means their body temperatures are determined by the external environment rather than by internal processes — in contrast to endothermic (warm-blooded) animals, such as birds and mammals.
