ID Tips

Oxypora colonies grow in delicate plating or wrinkled leafy forms.  The latter may have distinctive ragged colony edges.  Oxypora is predominantly found in protected, shallow reef zones.

The corallites range in size (4-10mm), are rounded in shape and may be level with the colony surface or raised slightly.  The costae are widely spaced and coarse, so may be clearly seen underwater running to the edges of the colony.

Similar genera to Oxypora (Coral Finder p19)

Oxypora may be confused with Echinophyllia, but they can be differentiated by examining the size of the corallites; Oxypora has smaller, less defined corallites, whereas those of Echinophyllia are larger and better developed.
