Hard soft coral: New genus and species of ‘living fossil’ octocoral related to blue coral

From phys.org | July 2, 2015 Research conducted in Okinawa, Japan, by graduate student Yu Miyazaki and associate professor James Davis Reimer from the University of the Ryukyus has found a very unusual new species of octocoral from a shallow coral reef in Okinawa, Japan. The new species can be considered a “living fossil”, and is related in many ways to the unusual blue coral. The study was published in the open access journal ZooKeys. Unlike scleractinians, most octocorals lack a …
