Saltwater Crocodile IUCN LEAST CONCERN (LC)


Facts about this animal

The Saltwater Crocodile has rather long snout, about 1.7 to 2.1 times as long as broad at the level of the front corners of the eyes. It has a bumpy bony ridge in front of each eye, extending forwards nearly to the nasal swelling. The colour of the upper body surface in young animals and semi-adult ones is remarkably light yellowish olive, with numerous dark spots all over the upper surface of the body; adult animals become somewhat darker in the course of growth. The lower surface is uniformly light, without dark spots or blotches. The iris is light greenish. It can potentially grow up to nearly 10 m, but is usually about 5.5 m.

Why do zoos keep this animal

C. porosus is not only a flagship species for its habitat but also for the conservative value of ranching in regard to its Australian populations. Its size and the corresponding requirements and its aggressivity however are probably the reasons why C. porosus is only rarely kept in zoos.
