CROCODILES

Crocodiles have been around since the age of dinosaurs! These living fossils have changed very little over millions of years, which means their design works perfectly for life in water and on land.

Crocodiles live in warm, tropical areas near rivers, lakes, and mangroves. In Costa Rica, they can often be seen along riverbanks and estuaries, always close to water, their favorite home.

Crocodiles glide through the water almost without a sound. Only their eyes and nostrils stay above the surface, which makes them look like a floating log until they suddenly move to catch their prey.

Crocodiles cannot make their own body heat, so they depend on nature to keep their temperature just right. When the day is cool, they warm up by basking in the sun. When it gets hot, they slide into the water or rest in the shade to cool down. This natural balance helps them stay strong and active.

A crocodile’s body is perfectly designed for stealth. Air-filled bones and specialized muscles help them float almost motionless, keeping their bodies hidden below the surface while they watch for movement above.

Crocodiles can live for 70 to 100 years! Their slow metabolism, strong immune system, and ability to survive long periods without food make them some of the longest-living reptiles on Earth.

Those glowing eyes aren’t just for show! Crocodiles have excellent night vision, allowing them to spot and catch prey even in the darkest waters.

Crocodiles have one of the strongest bites in the animal kingdom. Their powerful jaws can crush bones and hold on tight; but when their mouths are closed, tiny muscles can keep them shut with just a tap!

A crocodile never runs out of teeth. It can grow more than 3,000 new teeth during its lifetime, always replacing old ones so that its bite stays strong.

Crocodiles are incredible divers. They can stay underwater for up to fifteen minutes by slowing their heartbeat and using oxygen very efficiently while waiting for prey.

Crocodiles are skilled meat-eaters that feed on fish, birds, and small mammals. They wait patiently for the right moment, then strike with incredible speed. Once they catch their prey, they swallow it whole and use their strong tails to move swiftly through the water.

Crocodiles are more intelligent than they look. They can learn routines, remember feeding spots, and even recognize familiar humans over time. Their strong memory helps them survive for decades in the wild.

A crocodile’s back is covered with thick, bony plates called osteoderms or scutes. These tough scales act like natural armor, protecting them from predators and helping them absorb heat from the sun.
