Sagami Bay and Suruga Bay harbor a rich marine biodiversity; however, their outer-shelf scleractinian coral fauna has not been characterized to date. Scleractinian corals were collected by dredge sampling of the Japanese Association for Marine Biology (JAMBIO) Coastal Organisms Joint Surveys in 2015 to elucidate the diversity of azooxanthellate scleractinian corals from the outer shelf zones of Sagami Bay and Suruga Bay. In this study, a total of 1291 azooxanthellate scleractinian specimens were collected, corresponding to 23 genera and 18 species, five of which are new records for Sagami Bay and eight are new records for Suruga Bay. Moreover, in all localities, except sampling locality (SL) 8, more than 70% of the specimens showed asexual reproduction. This finding suggests that asexual reproduction may play an important role in increasing the coral population size in soft-substrate environments of the outer shelf.
相模湾和骏河湾拥有丰富的海洋生物多样性；然而，它们的外陆架石珊瑚动物群尚未得到描述。2015 年，日本海洋生物学协会（JAMBIO）沿海生物联合调查通过耙式采样收集了石珊瑚，以阐明相模湾和骏河湾外陆架区非共生石珊瑚的多样性。在这项研究中，共采集了 1291 个非共生石珊瑚标本，对应 23 属和 18 种，其中 5 种是相模湾的新记录，8 种是骏河湾的新记录。此外，除了采样点 8 外，所有地点的标本中有超过 70%表现出无性繁殖。这一发现表明，无性繁殖可能在外陆架软底质环境中对增加珊瑚种群规模起着重要作用。
