Distribution and habitat preferences

Fabricius and Alderslade (2001) note that Clavularia forms extensive mats on inshore areas of the Great Barrier Reef, favouring reef flats and other wave-exposed areas, whereas in areas with clearer water, it is uncommon and forms only small clumps. The genus is uncommon at Lizard Island and abundant at the Turtle Group which is about 13 nautical miles closer to the mainland.
