5 Things You Didn’t Know About Saltwater Crocodiles 

 

Saltwater crocodiles, also known affectionately as “salties,” are formidable predators, known for their massive size and powerful jaws. But there’s more to them than meets the eye! Here are five facts you probably didn’t know about saltwater crocodiles.  

POWERFUL JAWS

Their extremely powerful jaws are responsible for creating the strongest documented bite in the animal world. These reptiles can slam their jaws shut with a bite force of 3,700 pounds per square inch. That’s well over ten times more than the human average .

DEDICATED MOTHERS

Female crocodiles are dedicated mothers. They carefully build a nest of plants and mud and bury their eggs in it – up to 90 of them. The mother stays near her nest and protects it from predators. After about three months, when the eggs begin to hatch, mom unburies the nest and carries the newborn crocodiles to the water in her mouth. She stays with them as they learn to swim and hunt.

BIG EATERS

These crocs will chow down on almost anything. While juveniles eat smaller prey like insects, amphibians, small fish, and crustaceans, adults eat a wide variety of large prey including sea turtles, snakes, birds, buffalo, monkeys, and wild boar. A croc hunts steathily, with just its eyes and nostrils above water. When unsuspecting prey approaches, it lunges out of the water, kills its prey with a snap of its jaws, and then retreats back to the water with its meal.

HUGE REPTILES

Saltwater crocodiles are the largest reptiles alive! Adult males can grow to nearly 23 feet long and weigh over 2,600 pounds. Females tend to be smaller, topping out at about 9 feet.

BROAD HABITAT

Despite their name, they’re not restricted to saltwater! These crocodiles live on the coasts of northern Australia, Southeast Asia, and Southern India. While they often are found in coastal waters or rivers with salinity, they also frequent freshwater rivers, inland wetlands, and lakes.

 

Though adult saltwater crocodiles have few predators, these reptiles do face human threats when forced to cohabitate or compete for resources. Their habitat may also be degraded or destroyed by human development. The species is not currently considered at risk, but in many places, limited information makes it difficult to fully understand population numbers and the threats they face. Both populations and threats may also vary from country to country. By protecting coastal habitats around the world, we can help saltwater crocodiles and other species thrive.
