The most beautiful Christmas trees are living underwater

If you happen to be a character in a Christmas movie, you might be competing to decorate a prettier Christmas tree than your neighbors. But no matter how many lights you string around your tree or baubles you hook onto its branches, you'll never outdo the Christmas tree worm.

Yep. Believe it or not, that's a worm. These animals live underwater in tropical oceans. You can find them anywhere from Florida to the southern Israeli port of Eilat.

The worms use their gorgeous spirals to eat and breath. Using filter feeding, they catch tiny organisms.

Many aquariums purposefully include coral that Christmas tree worms inhabit because the animals are so gosh darn cool-looking.
