In captivity, crocodiles may live anywhere between 75 to 100 years, whereas in the wild, their average lifespan is reduced to between 50 to 70 years. The smaller crocodile species have a lifespan of 30 to 40 years. On the contrary, their close counterpart, the alligator, can live up to 70 years in captivity and 30 to 50 years in the wild. 

Underwater, crocodiles are unable to breathe. This is because they lack the gills that fish have. However, when fully submerged, they can hold their breath underwater for a considerable time. They can also float while breathing by sticking only the tip of their nose above the surface.

Crocodiles typically take a rest on the ground near the shore. Crocs in captivity usually rest on concrete made by humans. Crocodiles may also be seen dozing off while partially submerged in water.

Crocs can see at night. Crocs have evolved their eyes along with other physical traits. Additionally, to human eyes, they are quite similar in size and function. Much though crocodilians’ eyesight is not as acute as that of humans, it is still very good and gets even better at night.

Alligators and crocs also communicate, but not how we humans do. Of course, we know about meows, chirps, barks, and other commonly heard animal sounds. But what about crocodilians? These large reptiles know how to communicate, using audible infrasound and loud hissing and chirping.

Crocs and alligators are both carnivorous, and snakes are on their menu. However, snakes are not their primary prey. They may sometimes hunt down and eat snakes, they would mostly stick to other prey like crabs, turtles, fish, frogs, etc.

Crocodiles are not officially found in New Zealand. In other words, if the official assertion is to be believed, New Zealand is a crocodile-free country.

Most people believe crocodiles to be vicious creatures. However, this is not always the case. Although freshwater crocodiles are not known for being violent, they typically attack prey—especially humans—out of self-defense. They can also attack as the result of mistaken identity.

Crocodiles are said to be hostile. Aggression levels, however, differ between different species. The king of crocs and most vicious are saltwater crocodiles, or “salties.” These crocodiles exhibit some hostility even as juveniles.

Did you know that crocodiles can move in six distinct ways? And you thought they only swim in the water and crawl on land. But in actuality, this toothy reptile can swim, crawl, dive, belly-crawling, and high-walking. Crocodiles can also gallop over short distances. Incredible, isn’t it?
