Symbionts (IMAGE)
Caption
Because they all appear as tiny round spheres with few features to tell them apart, the symbiotic microscopic algae of corals were once thought to belong to a single species found in all reef-building corals. These symbionts are now recognized to be a group that comprises hundreds and possibly thousands of species that can be sorted into at least 15 genera.
