西南印度海岭是全球洋中脊系统中最长的一段缓慢到超低扩张的海底，但其热液喷口动物的生物地理学和生态学以前是未知的。首次遥控潜水器下潜至龙旗喷口区，深度2800 m，水深37°47′s， 49°39′e，共采集了21个大型和巨型动物类群。其他火山口有6种尚不清楚，而中印度脊有6种已知，形态和分子分析表明，还有2种多毛类与印度洋以外的火山口共有。通过对三大洋喷口动物群的多元分析，龙旗属印度洋喷口生物地理省。随着离喷口距离的增加，动物区系以腹足类（Chrysomallon squamiferum和Gigantopelta aegis）、贻贝类（Bathymodiolus marisindicus）和新竹类（Neolepas sp. stalked藤壶）为主。其他类群的丰度较低，在某些情况下与其他喷口区的丰度形成对比，龙旗地区分析的物种的δ13C和δ15N同位素值与其他地方的共有或近缘物种相似。这项研究提供了联合国在龙旗批准的矿产勘探活动之前的基线生态观测。
The Southwest Indian Ridge is the longest section of very slow to ultraslow-spreading seafloor in the global mid-ocean ridge system, but the biogeography and ecology of its hydrothermal vent fauna are previously unknown. We collected 21 macro- and megafaunal taxa during the first Remotely Operated Vehicle dives to the Longqi vent field at 37° 47′S 49° 39′E, depth 2800 m. Six species are not yet known from other vents, while six other species are known from the Central Indian Ridge, and morphological and molecular analyses show that two further polychaete species are shared with vents beyond the Indian Ocean. Multivariate analysis of vent fauna across three oceans places Longqi in an Indian Ocean province of vent biogeography. Faunal zonation with increasing distance from vents is dominated by the gastropods Chrysomallon squamiferum and Gigantopelta aegis, mussel Bathymodiolus marisindicus, and Neolepas sp. stalked barnacle. Other taxa occur at lower abundance, in some cases contrasting with abundances at other vent fields, and δ13C and δ15N isotope values of species analysed from Longqi are similar to those of shared or related species elsewhere. This study provides baseline ecological observations prior to mineral exploration activities licensed at Longqi by the United Nations.
