There are 13 species of otter worldwide (everywhere but Antarctica)—and sadly, 12 species of these marine mammals are vulnerable, threatened, or endangered. This is news that's hard to bear when confronted with their inherent cuteness, witnessed in recently circulating photos of mother-and-child pairs holding hands to avoid drifting away from each other as they snooze. Discover 14 more wild animal species you never knew were endangered.
Sure, they've got those long ears, all the better to hear you with—as AskNature.com points out, they can rotate these appendages 270 degrees in order to detect sounds, some from as far as two miles off, in almost every direction.

Now that's an incredible animal fact!
