Symmetrical Brain Coral

Aspect:	Generally dome-shaped aggregation of colonies that form long and deep-cut valleys, which are home to the polyps' mouths. The ridges are neatly rounded and feature a very thin (sometimes invisible) groove at their summit, where septa meet.
Population:	Common.
Notable feature:	Light brown to brown with generally lighter coloured valleys.
Environment:	Most usually on steady substrates like rocks, but also shipreck surfaces, at depths ranging from only a few tens of centimetres down to more than 30 metres.
Behaviour:	Tentacles may sometimes extend during the day.
