Crocodiles have inhabited the Earth for over 80 million years, and they have changed very little over that time period. They also have long lifespans, with some living beyond 100 years of age.
Crocodiles have between 60-110 teeth. When a crocodile loses a tooth, there is a small replacement already on standby. They are able to replace each of their teeth up to 50 times over their lifespan.
Crocodiles don’t sweat. To keep cool, they open their mouths which is known as “mouth gaping,” very similar to panting. They often sleep with their mouths wide open to release heat and stay cool.
Crocodiles are extremely fast in the water, swimming up to speeds of 22 mph (35 kilometers per hour).
It’s a common myth that crocodiles can run fast on land. They can ‘belly run’ up to 11 mph (17 kilometers per hour) for short distances.
Crocs can hold their breath underwater for more than an hour.
Larger crocodiles can go for over a year without eating a meal.
A croc’s metabolism is super efficient, using and storing nearly the entirety of the food it consumes.
In extreme circumstances, they are able to shut down and live off their own tissue for a long period of time.
Heron symbiosis. Nature also has its spaces for negotiation, a relationship between two species that generates mutual benefit. The best-known scene is that of the oral hygiene of the Nile crocodile, which opens its jaws and lets a small Egyptian plover pick between its teeth. In passing, the little bird removes the leeches that roam between the reptile’s gums. It’s what marketing analysts call a win-win case: everyone wins.
