Crocodiles are reptiles that typically range from 2.5 to 6.5 meters in length. They are found in tropical regions around the world and live in freshwater reservoirs, spending most of the day in the water. Crocodiles lay eggs on sand, eat meat as carnivores, and breathe with lungs. While slow on land, they can reach speeds up to 17 km/h in water by propelling with their powerful tails.
