Another marine animal that has managed to get off the list is the West Indian manatee, who went from being classed as an endangered species to a threatened species.

The good news was given by the United States Fish and Wildlife Service (USFWS) in 2017. Although the West Indian manatee is still a threatened species, this important step forward means that the population numbers of this marine mammal are increasing and that its natural habit is being restored. So it can be safely concluded that the international cooperation to preserve the species is working.
