Are manatees endangered?

The International Union for Conservation of Nature and the World Wide Fund for Nature classify manatees as "vulnerable." But the WWF says their status is "under debate."

The U.S. Fish and Wildlife Service downlisted manatees from "endangered" to "threatened" in 2017.

Major threats to manatee populations include poor fishing practices, boat collisions, habitat loss and pollution, according to the WWF.

Manatees are susceptible to bycatching, or when fishermen unintentionally catch something in their nets. This can injure or kill marine life. Manatees also live in shallow coastal areas and move slowly, making them more likely to be hit by watercraft.
