| Summary: | A new partially calcified hydroid species of the family Hydractiniidae, was found in offshore waters of the Aleutian Islands (Alaska), dredged from the bottom at 139–145 m depth. This is the third known species of extant calcified Hydractiniidae, and it shows a unique colony structure. The base is heavily calcified and the distal parts are ramified and have a solid chitinous structure. Branches are all in one plane and the colony reaches up to 18 cm in height. |
