The swimmers on a beach in the United Kingdom probably looked like they were straight out of the movie Jaws.
An 18-foot shark would put most swimmers on edge, but the folks on vacation had nothing to fear. Turns out the shark in question was a basking shark. It's known as a gentle giant--not for attacking swimmers.
"There were a few people swimming who got out pretty quickly but a few brave souls stayed around to have a look," says Tom George, who filmed the shark from his 18-foot boat.
Basking sharks are the second biggest fish in the world (reaching 20 to 26 feet), after the whale shark.
