This coral occurs offshore at depths ranging from 1 to 30 metres or three to one hundred feet deep.

The alga benefits from being in a protective environment in an elevated position.

The coral benefits from the nutrients produced by photosynthesis
by the alga which provides part of its needs for growth and calcification.

The coral also has a relationship with the long-spined urchin.

The grazing of the long-spined urchin helps to reduce the effects of shading.

This also helps reduce the overgrowth of macroalgae.

Where the common name comes from

The system of meandering grooves and ridges on their outer surface is where name comes from.

This surface resembles the appearance of the brain of higher animals.

Brain corals are reef-building species that form large and rounded colonies.


This coral is also commonly known as “depressed brain coral”.

Another name some use is “Labyrinthine Brain Coral”.
