Next time you scuba dive into the depths of the ocean, keep an eye out for crinoids. These creatures look like flowering plants from a garden, but as their "petals" wave through the water, they catch food as it passes. These animals have been living in Earth's oceans for over 500 million years. And some types are still alive today!
