Here we present the discovery of R. daphneae along the southern Central Indian Ridge, at the Rodriguez Triple Junction, and along the northern Southeast Indian Ridge within the German contract area for the exploration of marine massive sulfide deposits in the Indian Ocean. We used video sled and Remotely Operated Vehicles (ROV) to collect video imagery and recognized a total of eight individuals. The two supplementary videos report on one individual associated with polychaetes on its tentacles and oral disc and, and one individual of the giant anemone that was recorded for the first time, capturing prey, a shrimp of the species Rimicaris kairei. This will provide insight into the basic ecology of the rather elusive giant anemone, R. daphnaea. Supplementary video 1: Video imagery collect by the Remotely Operated Vehicle ROPOS (Remotely Operated Platform for Ocean Science, www.ropos.com) showing commensal polychaetes moving on an individual of Relicanthus daphneae from two different cameras. Arrows in the video indicate position of polychaetes on the giant anemone. Supplementary video 2: Video imagery collect by the Remotely Operated Vehicle ROPOS (Remotely Operated Platform for Ocean Science, www.ropos.com) showing an individual of Relicanthus daphneae capturing prey (Rimicaris kairei). Arrows in the video indicate the position of the shrimp R. Kairei captured by the giant anemone.
