Watch | Breathtaking feather like sea lily filmed swimming

A diver has managed to capture video of a rare swimming sea lily. A professional diver, Els van den Eijnden, from the Netherlands, spotted the Feather Star on a dive in Thailand. Although the crinoids also known as sea lilies are commonplace, they are usually attached to rocks or coral. But in Els's rare footage, the creature appears to have been knocked from its base and has to swim.
