Description: An irregular bushy hydroid, forming a colony which is somewhat conical in outline. The individual polyps are athecate with two rings of tentacles angled to each other. The reproductive structures produce free-swimming medusae. Colonies measure 70-120mm in height, polyps are about 3mm in length.

Habitat: Usually in fairly wave sheltered conditions, often in slightly reduced salinity.

Distribution: Widespread in the British Isles.

Similar Species: A rather non-descript straggly hydroid, with no good distinguishing features.
