Blastoids, commonly known as "Sea Lillies", are ancient animals very similar to starfish. They had a long stem like structure and a system of “roots” to hold them in the sediment of the sea floor. They spent their lives slowly filtering food from the water, using their arms to transport the food down to their mouth. Blastoids are no longer around, having died out at the end of the Permian Period, about 225 million years ago.
