Crinoids (black) attached to a sea whip on a coral reef. A sea whip is an elongated relative of the true corals, a colonial organism made up of thousands of tiny polyps that filter plankton from the water. Crinoids are echinoderms, relatives of the starfish, which also filter plankton from the water using their feathery tentacles. Unlike sea whips, they can detach themselves from their substrate and swim until they reach a more favourable site. Filmed in East Timor.
