A saltwater crocodile was spotted roaming the Sundarbans recently. Native to saltwater habitats, brackish wetlands, and freshwater rivers, saltwater crocodiles are known as the largest living reptiles in the world.

These opportunistic carnivores can prey on almost any animal that enters their territories, including sharks and humans. They often ambush their prey and swallow it whole.

What is more interesting is that saltwater crocs have been found to sleep with one eye open, keeping one-half of the brain awake and alert for predators.

These giant but majestic beasts of the seas are often threatened by illegal killing and habitat loss, pushing them to the brink of endangerment.
