Feather hydroid

In Dive.Explo360: Mediterranean · Northeast Atlantic · Atlantic Ocean

Standing facing the current, the Feather hydroid resembles a delicate underwater feather. Its finely divided branches intercept suspended particles, while the colony offers discreet refuge to many small seabed organisms.

WHAT DOES IT LOOK LIKE?

This colonial hydrozoan forms upright feather-shaped structures, with a main axis bearing numerous regular branches. The whole has a fine, finely divided appearance. The colony is generally brownish to yellowish depending on the individual and environmental conditions. Small polyps are arranged along the branches and perform the colony’s vital functions.

WHERE DOES IT LIVE?

It is encountered attached to hard substrates, often in areas exposed to currents. It can be observed on rocky seabeds or secondary supports near softer areas.

WHAT DOES IT EAT?

It feeds by catching particles and plankton carried by the current. The polyps capture food and distribute nutrients throughout the colony.
