Sessile Hydrozoan

Halopteris carinata

• Group: Other
• Typical depth: 1–161 m

A feathery colonial hydroid of shallow coastal bottoms, it grows on dead coral and sea fans down to around thirty metres, with records reaching much deeper. Polyps catch plankton from the current, and the colony releases a drifting medusoid stage to spread.
