Where seen? These tiny white straws are sometimes seen on our shores on coral rubble.

Features: Clusters of short delicate white or transparent straws 1-2cm tall.

Species with these forms include Oceanapia sp. "white fistules" which have a hollow globular body topped with several white fingers. Aka aff. maldiviensis burrow into calcium carbonate structures with only 1-3 white fingers sticking out. Leucosolenia sp. form clusters of hollow white tubes often under rocks and in crevices. Some Haliclona species also form tiny hollow white tubes.
