General Diagnostics: Focal, multifocal and coalescing lesions with a linear margin. Linear or annular tissue loss initiating at the base or perimeter of a colony, or from the margin of an old lesion and progressing as a front 1mm to 10cm/day.

Fish territories occur among corals; bite marks denude tissue in a focal or multifocal pattern (N). Lesions may progressively expand in annular manner, and new lesions appear in other locations.
Aggregates of snails may remove tissue in a focal or annular pattern; snails may be on the lesion or at the perimeter of the colony. Parrotfish predation may result in multiple small focal or multifocal lesions and larger annular bands that progressively expand in size; these have tissue loss and skeletal damage.
