on corals in the Gulf of Eilat. It occurs in groups of non-overlapping individuals, causing the corals it inhabits to appear spotted. It has been detected on 13 species of stony corals, and on one species of soft coral. It can be found at depths of 2 to 50 meters. The presence of Waminoa species on live corals brought about several hypotheses about the nature of this coral-acoel association, one of which was that the acoels feed on the coral's mucus. A recent study by Naumann et al. (2010) corroborated this hypothesis. References Acoelomorphs
