CORALS may be harmed by their natural enemies or by environmental conditions. The ability of scleractinian corals to regenerate damaged parts has been documented qualitatively by many investigators1-10, but detailed quantitative data on the rate of regeneration have not been reported. Most reports dealing with the destruction of coral reefs have emphasised the long time required for recovery11. I have found, however, that the rate of skeletal regeneration in a population of the branched coral Stylophora pistillata (Esper) is surprisingly fast. During the first 2 months of regeneration, damaged colonies grew twice as fast as intact control colonies. Within the same colony, damaged branches grew faster than intact branches, which resulted in a tendency to regain symmetry lost through breakage. Larger colonies showed a better capacity to resist damage than smaller colonies.
