Crocodiles can hear, in fact, they have a strong hearing sense that is often compared with that of elephants. Their hearing range varies b/w 100-3000 Hz, which means they can detect high-pitched sounds that even humans can’t hear. 

Crocodiles cannot regrow their limbs like other smaller reptiles such as lizards, geckos, and iguanas. Alligators are the only largest animals known to regrow their limbs. 

Crocodiles are cold-blooded, meaning they cannot generate the heat their body needs for survival. Instead, they rely on their external environment to derive the required heat. As such, their body’s temperature fluctuates depending on their environment’s temperature. Conversely, they can cool down their bodies by spending more time in water. 

No, crocodiles do not die of old age, and if all factors remain constant, they may live up to 100 years. However, most crocodiles die before they reach that age due to external factors such as loss of habitat, attacks by hunters who are seeking them out for their hide, and attacks by other crocodile species. Besides, natural disasters are one of the leading causes of a crocodile’s death.

You’re likely aware that crocodiles can be found in rivers, swamps, and other waterways, but did you know they can also be found in the ocean? Surprisingly, it is believed that crocodiles are present in most of the world’s major oceans and seas, including the Atlantic Ocean. 

Crocodiles live in various parts of the world, including Asia, Africa, Australia, and even America. You can usually spot them near lakes, creeks, wetlands, and saltwater regions. Being cold-blooded animals, their body cannot generate heat, and as such, they rely on hot, humid climates to keep them going.
