Lobophyllia; the Brain Corals

Lobophyllia are the family members that actually live up to the name of brain coral. If you get the chance to go night diving here on Koh Phangan they no longer look like monster brains, as they extend their tentacles to feed…

An ex- Symphyllia species - flabello-meandroid with very wide valleys.

Not truly fan-shaped, but with more projecting bits than the other lobophylliids.

Can be confused with Lobophyllia hataii below.

Another flabello-meandroid lobophyllid.

Featuring thicker walls, wider valleys and a less meandroid growth form than S. recta below.

Hemispherical to flat in form, featuring meandering valleys and fused valley walls (meandroid).
