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.
