Diversity of azooxanthellate scleractinian corals collected from northwest of Kyushu during cruise GB23
The East China Sea is rich in marine biodiversity, although the azooxanthellate scleractinian coral fauna has yet to be characterized in this region.To address this limitation, azooxanthellate scleractinian corals were collected northwest of Kyushu using a Kinoshita-type grab sampler during marine geological survey cruise GB23.A total of 687 azooxanthellate scleractinian specimens were collected, representing 23 genera and 19 species.Peponocyathus folliculus specimens were obtained from 79 of the 163 sampling sites.This infaunal species exhibits automobility and undergoes transverse division (asexual reproduction) during the anthocaulus and anthocyathus stages.This indicates that asexual reproduction and automobility play an important role in increasing the population size of azooxanthellate solitary corals in soft-substrate environments.
