Figure 1From: EvoDevo meets ecology: the Ninth Okazaki Biology Conference on Marine BiologyCoral polyps in symbiosis. (A) Light micrograph of an Acropora digitifera polyp, with an endosymbiotic Symbiodinium visible as multiple brown spheres in the coral tissue. (B) Confocal micrograph of a naturally fluorescing Pocillopora damicornis polyp. Red spheres are Symbiodinium with chlorophyll autofluoresence. Blue and green pigment is from host-derived fluorescent proteins.
