### Instruction: Is the manatee an endangered species?
### Response: All three species of manatee (Amazonian manatee, West Indian manatee, and the West African manatee) are listed by the World Conservation Union as vulnerable to extinction. However, The U.S. Fish and Wildlife Service (FWS) does not consider the West Indian manatee to be "endangered" anymore, having downgraded its status to "threatened" as of March 2017. They cite improvements to habitat conditions, population growth and reductions of threats as reasoning for the change.
