1. The largest reptiles in the world: Crocodiles
Crocodiles are some of the largest reptiles in the world, with some species reaching an impressive length of up to 18 feet! This is more than twice the size of an average human, making them a formidable presence in the wild. Crocodiles are found in tropical and subtropical regions around the world, and they are known for their powerful jaws and sharp teeth. They are also excellent swimmers, and can stay underwater for up to an hour at a time.
2. How Crocodiles Keep Cool
When in a relaxed pose, crocodiles often keep their mouths open to cool down, rather than to show aggression. This is because crocodiles have the unique ability to sweat through their mouths, allowing them to regulate their body temperature. This is an adaptation that has allowed them to survive in hot climates for millions of years.
3. 24 Teeth That Will Grasp and Lock onto Prey
Crocodiles have an impressive set of teeth - 24 in total - that are designed to grasp and lock onto their prey. These teeth are constantly replaced as they wear down, ensuring that the crocodile always has a sharp set of chompers. In addition to their teeth, crocodiles also swallow stones to help grind up their food in their stomachs.
4. Thriving in Fresh & Salt Water
Crocodiles have an incredible adaptation that allows them to survive in both fresh and salt water environments: salt glands in their tongues. These glands excrete salt, making them highly tolerant to salt water and allowing them to thrive in both fresh and salt water habitats. This adaptation is especially useful for crocodiles that live in estuaries, where the water is a mix of both fresh and salt water.

5. How Crocodiles See in the Dark
Crocodiles have a unique adaptation that allows them to see in the dark: a membrane behind their retina called the tapetum. This reflective layer reflects light back through the retina, giving the crocodile's eyes a distinctive red glow at night. This adaptation allows them to hunt and navigate in the dark, giving them a distinct advantage over their prey.
6. Crocodiles are incredibly powerful swimmers
Crocodiles are incredibly powerful swimmers, capable of reaching speeds of up to 40 km per hour thanks to their powerful tails. Not only that, but they can also stay underwater for up to 3 hours at a time, making them one of the most formidable predators in the water.
7. Crocodiles can live up to 80 years
Crocodiles are some of the longest-living reptiles on the planet, with some species able to live up to 80 years in the wild. This impressive lifespan is due to their slow metabolism and the fact that they grow and mature slowly. In captivity, crocodiles can live even longer, with some individuals reaching over 100 years of age.
8. Crocodiles become highly aggressive during mating season
During mating season, crocodiles become highly aggressive, and they can produce anywhere from 20 to 80 eggs in a single season. After the eggs are laid, they take around 3 months to incubate, resulting in a total gestation period of 80 days.
9. The Softest Skin in the Animal Kingdom
The skin of a crocodile is incredibly soft and fine, making it highly sought after by some tribes who regard it as a symbol of high status. In fact, the skin is so soft that it is often used to make luxury items such as wallets, purses, and even clothing. The unique texture and durability of the skin make it a highly sought after material, and its use as a symbol of high status is a testament to its value.
10. crocodiles use their powerful tails to wipe their eyes
When feeding, crocodiles use their powerful tails to wipe their eyes, which start frothing and bubbling due to the intense activity. This behavior has given rise to the popular saying "crocodile tears", which refers to someone who is pretending to be sad even though they are not. Despite this, crocodiles are definitely not sad when they are feeding - they are simply taking care of their eyes!
