Sessile Hydrozoan

Sertularella gayi

• Group: Other
• Typical depth: 25–1453 m

This hydroid grows as a feathery branching colony anchored to rock, each stem lined with tiny cups that shelter the individual polyps. It reaches from shallow coastal slopes down past 1,400 metres, including the tops of seamounts, straining plankton from passing currents.
