Spirobranchus giganteus

These marine worms are like whimsical, miniature pine trees, earning them the common name Christmas tree worms. Popping up along coral reefs in a variety of colors and patterns, these worms use their feathery appendages for absorbing food and oxygen under the water.

They may seem like little plants, but they are animals, complete with a brain and a central nervous system! Granted, they don't really use their brains as much as we do – they latch onto the coral reef and stay there, letting their filtering crowns do all the food gathering. If it finds a spot it particularly likes, a Christmas tree worm may stay burrowed in the coral for up to 40 years.

At barely over an inch tall, these worms are like tiny, colorful pine cones dotting the reef.
