Round Island Burrowing Boa

The Round Island burrowing boa was completely wiped out by the year 1975. Being a remote and uninhabited island, Round Island could not cater for the overgrazing of goats and rabbits. The details of the boa’s diet are not entirely clear, although experts suspect that the snakes ate lizards.

Tasmanian Tiger

The Tasmanian tiger reached extinction in 1936. It once lived in Papa New Guinea and Australia but it was hunted to extinction everywhere but in Tasmania. The last surviving Tasmanian tiger lived in a zoo in Tasmania but he died when he was left out during a cold night and died due to exposure.
