10 Heaviest & Largest Crocodile Species
What is a Crocodile?
Crocodiles are awe-inspiring, ancient reptiles that have roamed the Earth for millions of years. With powerful, streamlined bodies, webbed feet, and muscular tails, they are perfectly adapted to their aquatic lifestyle. These carnivores are apex predators, lurking silently at water's edge, their eyes and nostrils atop their heads, allowing them to stay submerged while scanning for prey. Their notorious V-shaped snouts house a fearsome array of sharp teeth, and they exhibit extraordinary patience, remaining motionless for hours, before unleashing lightning-fast attacks on unsuspecting animals that venture close.
Found in a range of habitats, from freshwater rivers to saltwater estuaries, crocodiles exhibit fascinating behaviors. They regulate their body temperature through basking and cooling off in water. Mother crocodiles are devoted caretakers, guarding nests and even carrying hatchlings to water in their mouths. Here is a list of top 10 heaviest & largest crocodile species found in the world.
Heaviest & Largest Crocodile Species In The World
10. Saltwater Crocodile
