A curious manatee gives two swimmers a shock, scaring them back to shore on Florida's west coast.
The large marine mammal is seen gliding through the water before the two girls spot the dark object in the water - and they both quickly swim back to the shore.
The filmer told Newsflare: "Two girls were swimming about 125 feet from the beach when they spotted a dark shape in the water coming towards them.
"Not realising it was a manatee, they both swam to shore as fast as they could.
"The manatee has been dubbed 'Boo' because it regularly swims along the beach and startles people."
