Waminoa is a genus of acoels which are epizoic on living corals, using the coral's mucus as a source of food.

[1] Unusually, these acoels harbor two genera of endosymbiotic dinoflagellates: Symbiodinium and Amphidinium;[2][3] it is not typical for two different genera of dinoflagellates to coexist in a single host.

Waminoa's host coral may also contain dinoflagellates of the genus Symbiodinium but not Amphidinium.

[4] Only two species belonging to this genus have been discovered (W. litus and W. brickneri) and they inhabit coral reefs in the Red Sea,[5] Australia,[2] and Indonesia.
