Feather star swimming video

A short video showing a feather star swimming.

Definitely not a cichlid or even a freshwater creature, but impressive enough to post a video. This is a crinoid and they’ve been around for at least 300 million years. They are usually found on rocks where they feed on food particles with the help of their arms. Related to starfish and sea urchins, crinoids come in many different shapes, colors and sizes. Some spend their entire lives attached to a rock and appear to be a flower with a stalk. These stalked crinoids are commonly called sea lilies. Other crinoids can walk and swim and are referred to as feather stars. All types of crinoids are usually found in deep waters.
