A variety of species rated “Extinct In The Wild” are at the moment being raised and bred in captivity within the hope that they will finally be re-introduced into the wild.
There’s a glimmer of hope for these species, as a number of such reintroductions have been profitable prior to now. (Examples of profitable animal reintroduction embody the Arabian oryx within the Center East, and the black-footed ferret within the USA).
Examples of species that turned extinct within the wild in 2022 embody Garrett’s Tree Snail (Partula garrettii), and the Raiatean Floor Partula Snail (Partula navigatoria).
Each of those species had been discovered on the island of Raiatea, certainly one of many islands that make up the island nation of French Polynesia. Their extinctions are thought to have been brought on by the introduction of the Rosy Wolf Snail (Euglandina rosea), an invasive species that preys on different snails.
Extinct
Animals rated “Extinct” are not discovered both within the wild or in captivity. They’re assumed to have gone the identical means because the dodo, passenger pigeon, thylacine, and T-rex.
By no means once more will they be seen alive on our planet.
