Why do zoos keep this animal

Due to its relatively small size (2,5 m) and its social behaviour C. johnsoni can be kept also in zoos with limited space and budget. It is a keystone-species for its unique habitat, the rivers and billabongs of the tropical parts of northern Australia and has therefore educational value. With its narrow snout it is also quite attractive and is on exhibit in several zoos, some of which have been breeding the species.
