The Spirobranchus giganteus, also known as Christmas tree worms, are underwater creatures found in coral reefs.

They get their nickname because of the twin spirals that protrude from their body. The hair-like appendages are attached to the spine of the worm, which helps them eat and breathe.

And once they find a place they like, they won't move. Christmas tree worms anchor their bodies to the coral reefs, burrowing holes in their new home.

So if a scary predator happens to come swimming by, they can quickly retreat.

Although they are small -- only about four centimeters big -- you'll still be able to pick them out on your next dive because of their bright colors.

So go ahead and get in the holiday spirit by taking a quick dip.
