Nirvana girl Jade!, yes, they were around at the time of the dinosaurs and still here

Rey, Saltwater crocodiles in Australia live in both salt water and freshwater. We also have smaller freshwater crocodiles in Australia.

Player #7850667, as many as 3 octaves.

Nirvana girl Jade!, they are too scary for me!!
