Species of acoel
Waminoa litus is a species of dinoflagellate-bearing acoel which is epizoic on living corals.[1][2] This species is unique in that it transmits its endosymbiotic dinoflagellates (zooxanthellae) vertically (from the parent host to the offspring) via eggs, regardless of the heterogeneity of the zooxanthellae.[2] Two dinoflagellate genera have been found to simultaneously live in the parenchyma of W. litus: Symbiodinium and Amphidinium.[2]
