Thanks to their high-set nostrils which poke out of the water, crocodiles can creep up on unsuspecting victims easily. That’s because the rest of their body is concealed under the waterline.

Crocodiles share a lot of characteristics in common with lizards and other reptiles. However, what’s surprising is that these scaly creatures are actually more closely related to birds than their reptilian cousins. Like birds, they are the only living animals that can trace their ancestry directly back to the dinosaurs.
Saltwater crocodiles can be considered the kings of the crocs, at least as far reputation and size are concerned. The species as a whole is enormous, but Australian saltwater crocodiles can grow up to 20 feet long and weigh over a ton.
