Crocodylus niloticus, the second largest reptile on Earth after this beast;
Crocodylus porosus. The Saltwater crocodile. The largest reptile on Earth. Lots of teeth, intelligent, and for its size very quick and agile. Not all crocs are angry though;
This croc is a juvenile Nile crocodile she had an itch that needed scratching.
