“On 25 June 2014, a large number of small free-living Heteropsammia cochlea (Spengler, 1781) corals were observed feeding on salps on the sandy seafloor at a depth of 14min Leuk Bay, Koh Tao, Gulf of Thailand (N 0°04′08.9″, E 099°50′31.6″). Over 100 corals showed different stages of salp consumption (at least 150 individuals) without any signs of rejection. Most captured salp zooids were solitary, and a few were part of short chains. They likely belonged to Iasis cylindrica (Cuvier, 1804), because of the stolon projecting forward (pers. comm. R.W.M. van Soest). During succeeding observations (March-
June 2015), H. cochlea individuals were observed again feeding on such short salp chains (2–4 individuals).”
