Nanipora Miyazaki & Reimer, 2015 is a recently discovered genus of aragonite-skeleton producing octocorals closely related to the blue coral genus Heliopora de Blainville, 1830. Since its discovery, Nanipora has been reported from coral reefs in Okinawa, Japan, and Thailand, and from seagrass beds in the northern South China Sea. However, it remains little known and studied. Here, we report on the unexpected discovery of an abundance of Nanipora colonies in shallow waters less than 2-m deep around a CO₂ vent from the uninhabited volcanic island of Iwotorishima, Okinawa, in southern Japan. Nanipora colonies were found covering both coral rubble and hard substrates, alongside a few soft coral and zoantharian species. Polyps were pale white in color with none brown or darker in coloration as in some recent reports. As the original description of N. kamurai from Zamami Island in Okinawa describes the species as azooxanthellate, as the current Iwotorishima specimens also appear to be, and recently reported specimens from Thailand, Dongsha Atoll, and Yaeyama are zooxanthellate, it may be that there are more than one Nanipora species; the type species N. kamurai that is also likely at Iwotorishima, and a zooxanthellate species that constitutes the other records. Although Nanipora is not well studied, its presence at this volcanic CO₂ seep suggests it has the ability to survive under unique and extreme environmental conditions, rendering it as a potentially important subject of study in the face of increasing ocean acidification.

Nanipora Miyazaki＆Reimer，2015年是一个新发现的文石骨架八叶虫属，与蓝色珊瑚属Heliopora de Blainville属密切相关，1830年。自发现以来，据报道，在冲绳，日本和泰国的珊瑚礁中发现了Nanipora，并且来自南海北部的海草床。但是，它仍然鲜为人知和研究。在这里，我们报道了在日本南部冲绳县无人岛火山岛CO ₂喷口周围不到2米深的浅水区，发现了Nanipora菌落的大量意外发现，该区域周围不到2 m 。Nanipora殖民地被发现覆盖了珊瑚的瓦砾和坚硬的底物，以及一些软的珊瑚和zoantharian物种。息肉的颜色为浅白色，没有褐色或较深的颜色，如最近的一些报道所示。作为N的原始描述。冲绳县座间味岛的武士将该物种描述为偶氮黄菊，因为目前的岩ori岛标本似乎也存在，并且最近报道的泰国，东沙环礁和八重山的标本是人黄藻，这可能是不止一种Nanipora物种；类型物种Ñ。岩手岛也有可能出现的小武士，而构成其他记录的虫黄藻物种。虽然Nanipora由于没有很好的研究，它在这种火山CO ₂渗流中的存在表明它具有在独特和极端环境条件下生存的能力，使其面对日益增加的海洋酸化可能成为潜在的重要研究课题。
