In the 1980s, dholes that inhabited North America disappeared from the wild. In 1987, zoologists managed to return the animal to the wild. And now the wolves often mate with coyotes, threatening the former’s existence as separate species.

However, Tristan albatrosses, with a wingspan of more than three meters, have already disappeared from Tristan, the main island of the Tristan da Cunha Archipelago, in the southern Atlantic Ocean. The birds are now endemic to Gough Island, where there are no more than 2,700 pairs. The birds often die after becoming entangled in fishing nets.

At present, the population of marine angelfishes is extremely unstable and remains endangered due to fishing for tropical fish collectors.
