How the Haddon's carpet anemone lives

Its long body is usually buried in sand, with a disk at the bottom anchoring it. Sticky tentacles grab small fish and crabs and pull them into its central mouth to be swallowed whole. Out of water, it shrinks and makes a layer of mucus to retain moisture. Its larvae drift with ocean currents and eventually settle on a surface.
