The Haenyo Are South Korean Mermaids
1 of 5
Remember when you watched The Little Mermaid, then told your entire class that you wanted to be a mermaid when you grew up? No, just us? We digress. A group of elderly South Korean women are considered real-life mermaids, diving depths of up to 65 feet (20 meters) without any oxygen tanks. Beat that, Ariel.
Giant Squid Have Donuts For Brains
2 of 5
In addition to having eyeballs the size of dinner plates and suckers that can leave scars, giant squid have some freaky brains. The organ is small and donut-shaped, with a hole in the middle that accommodates the squid's esophagus. However, this means that the squid can't swallow anything too large, as it could cause its throat to bulge against and damage its brain!
A Squid In The Sky

Contrary to the belief that they only jump out of the water, neon flying squids actually achieve controlled flight. These squids eject water at high pressures from holes near their heads. Each flight lasts around three seconds and can cover more than 30 meters at once.

How Big Are Giant Squids?
5 of 5
Giant squid are indeed giant, but their size has been exaggerated by a fascinated public over the years. The largest giant squid that's been scientifically documented was 13 m (43 ft) long. They can grab prey with their long feeding tentacles from up to 10 m (33 ft) away, using the sharp hooks in their suckers to latch on. The squid's "tongue" is similarly sharp: it's a tooth-covered organ called a radula, which sits inside a beak.
