Coral under the microscope (IMAGE)
Caption
Three views of the coral include, top left, a fish-eye view of the algae-encrusted coral; top right, a microscopic view of one wall of the hollow coral; and, bottom, a high-resolution micrograph of a section of the same coral. This analysis revealed that a host of tiny organisms were simultaneously stabilizing the coral’s exterior surfaces and hollowing out its interior.
