ID Tips

Echinophyllia colonies grow in an encrusting to tiered-plating form, and may be found across all reef zones.  Some species are common.

The corallites are mid-sized (5-10mm), may be oval or rounded in shape, but tend to look untidy or irregular.  The septa and costae are numerous and clearly seen through the overlying tissue giving a ragged appearance that adds to the irregular look underwater.
