Pulsing Coral

Xenia elongata


Why do these corals pulse? It is not to catch food. It is not a form of hypnosis or a dance or a message to Alien observers from the Planet Corallius to come and destroy humans for not taking care of the Reef. Xenia are super-photosynthesisers and they do it so fast that they pulse to pull in more of the CO2 and dissolved nutrients they need to photosynthesise. Guardian: Florian Izko

Your spotting has been nominated for the Spotting of the Week. The winner will be chosen by the Project Noah Rangers based on a combination of factors including: uniqueness of the shot, status of the organism (for example, rare or endangered), quality of the information provided in the habitat and description sections. There is a subjective element, of course; the spotting with the highest number of Ranger votes is chosen. Congratulations on being nominated david14!
