Sessile Hydrozoan

Eudendrium attenuatum

• Group: Other
• Typical depth: 4–110 m

This branching hydroid grows on mangrove roots, dead coral and gorgonians, from shallow patch reefs out to the continental shelf. Its colony reaches past a hundred metres in places, and like its kin it releases tiny free swimming medusae into the plankton.
