Tubelip Wrasse Feeding on Coral (IMAGE) Cell Press Caption This slow-motion gif shows a tubelip wrasse using its mucus-coated lips to feed on the surface of corals. When they feed, these fishes close their mouths, push their fleshy lips against the coral, and suck off the mucus and tissues. These 'kisses' are possible thanks to a coat of mucus around their lips Credit Victor Huertas and David Bellwood Usage Restrictions Credit required License Licensed content Disclaimer: AAAS and EurekAlert! are not responsible for the accuracy of news releases posted to EurekAlert! by contributing institutions or for the use of any information through the EurekAlert system.
