Dendrogyra cylindrus

(Ehrenberg, 1834)


Ehrenberg, 1834

Characters: Colonies have encrusting bases on which cylindrical columns are developed that may reach 2 metres in height. Valleys are meandroid. Septo-costae are thick, in two alternating orders; they do not join at the tops of valleys and thus leave a neat groove along the tops of walls. Tentacles remain extended during the day giving columns a furry appearance.

Colour: Grey-brown.

Similar Species: Superficially resembles Scapophyllia cylindrica.

Habitat: Most reef environments.

Abundance: Uncommon but conspicuous.

Taxonomic Note: Very distinct species.
