The Squid Worm Lives Half A Mile Underwater
Fans of SpongeBob may be at least a little bit tempted to call this funny-looking creature a Squidward, but it is a squid worm. Squid worms were only discovered in 2010, during explorations off of Indonesia. They live about 3000 feet underwater.

This worm pretty much rises and falls with the ocean currents that pass through, feeding on algae and plankton. It is usually about 9 centimeters long, though there could be plenty of other specimens that are significantly smaller or larger. They were only recently discovered, so scientists have a lot more to learn about them.
