We documented the microscopic morphology of tissue healing in Montipora capitata. Fragments from two healthy coral colonies were traumatized by scraping tissue and skeleton and monitored in flow-through seawater tables every 2-4. days for 40. days for gross and cellular changes. Grossly, corals appeared healed and repigmented by Day 40. Histologically, traumatized issues were undistinguishable from intact untraumatized tissues by Day 12. We suspect that the calicoblastic epidermis of basal body wall is pluripotential and can develop into surface epidermis when needed. ?? 2010.
