Can crocodiles survive Europe?

Antarctica and Europe are the only continents without native species of crocodile.

What are some traits that allow the crocodile to survive in its environment?

There are special bony flaps in the throat which allow a crocodile to eat when submerged or breathe when its jaws are open underwater. Crocodilians, being cold-blooded reptiles, have to avoid extremes of temperature. When it is fairly cool, they rest on a waterside bank, allowing the sun to warm their body.

What movement are some crocodiles capable of?

Large, solidly built, lizard-like reptiles, crocodilians have long flattened snouts, laterally compressed tails, and eyes, ears, and nostrils at the top of the head. They swim well and can move on land in a “high walk” and a “low walk”, while smaller species are even capable of galloping.

What are the three roles of crocodiles for other animals?

They help keep the balance in the complex web of life in freshwater and estuarine ecosystems. They are key predators at the top of the food chain and eat a wide range of prey. They are also prey, when smaller, to other animals such as feral pigs, goannas, turtles, barramundi, sea eagles and even other crocodiles.

Why are crocodiles not found in Europe?

Scientists say Europe has no natural crocodiles because the cooling planet caused a reptilian retreat to warmer climes.

Do crocodiles eat once a year?

A croc’s metabolism is so evolved that its body uses and stores nearly the entirety of the food it consumes. This is one reason why larger crocodiles can go for over a year without eating a meal. But most crocs eat much more often than that. In fact, the average croc eats about 50 full meals a year.

Why do crocodiles lie in the sun?

When a crocodile is basking, or laying in the sun, it is raising its body temperature. When it wants to cool back down it can move out of the sun into the shade or a body or water. This behavior is a way for the crocodile to release the heat from its body.

What makes crocodiles different from other reptiles?

Despite their prehistoric look, crocodiles are among the more biologically complex reptiles. Unlike other reptiles, a crocodile has a cerebral cortex and a four-chambered heart. Crocodilians also have the functional equivalent of a diaphragm by incorporating muscles used for aquatic locomotion into respiration.

What is the role of crocodile in the ecosystem?

The Wildlife Conservation Society of the Philippines (1997: 81) argued that “crocodiles are important to aquatic ecosystems, not only in keeping the balance by controlling population growth of prey species, but also valuable in the maintenance of residual waterholes during dry periods and inhibition of encroachment of …
