Climacocodon ikarii
Taxonomic Group: Cnidarians-Hydrozoans


Climacocodon ikarii is a hydrozoan whose polyp and medusa forms are both planktonic. It was first described from Oshoro, Hokkaido, on the Sea of Japan. It has been introduced to central California and Coos Bay, Oregon. Because of its fully planktonic life cycle, many details of its life history and ecology are unknown. There are no reported impacts from its native or introduced range.
