Giant, scaly, stealthy, toothy, prehistoric – these are all words that describe crocodiles and their friend alligators. These reptiles have been around for 240 million years, even older than hippos I talked about a few days ago. They have evolved into lean, mean, killing machines over the last few millennia.
GENERAL STATS : in order to survive at the same time as the dinosaurs, they must have been pretty amazing and tough. A Saltwater croc is the largest reptile – up to 7 meters long and weighing up to one ton at largest. They can actually live pretty long lives, living about 70 years. However, most hatchlings (99%) die early on in their lives. Luckily, the ones that live become apex predators.
BODY FEATURES: Crocodiles have adapted to their environment for almost 250,000,000 years. So, of course, they have many awesome body features that they have evolved.
Crocodiles have the strongest bite of any animal in the world, as I have talked about in previous blogs. They have up to 34 teeth per jaw, clamping for clamping down and ripping apart prey. When swimming, their nostrils close and they have actually very sensitive ear flaps. Their skin is very tough. So strong, in fact, that the ancient romans used crocodile skin as armour. After all, it could block old-fashioned bullets! To help them swim, crocs also have a tail made nearly entirely out of muscle and a smooth underside to slide across the riverbed. They short, stubby legs help them steer, but don’t work very well on land.

HUNTING: every apex predator needs meat to survive. Crocodiles have developed one of the most efficient and deadly strategies. First, crocs wait for their prey (medium sized hoofed mammals) to come to the river they are lurking in for a drink. They slowly float towards their target, acting as a log. The fact that their eyes and nostrils are on top of their head helps. Then, when the croc is close enough, it will go sink underwater and start gliding in. Finally, it leaps up at amazing speeds and grasps an antelope. It then drags it into the water, shredding it to pieces. Crocs often need helpers to aid them when doing the ‘death roll’. They spin in the water, tearing chunks of flesh off once in a while. The smaller ones, to small to actually hunt, can find food this way. A crocodile’s tongue is even stuck to the bottom of its mouth so that it is easier to swallow.

Crocodiles are some of the most adapted animals in the world. Do you think that they can still evolve? Or do you think that they are already perfect? Think about it.
Fun fact: Once, a saltwater crocodile got homesick after being moved from its birthplace. It swam 362 kilometers to return home. Whew!
Fun fact 2: Crocodiles can spend more than 2 hours underwater at a time.
