资源简介：

Surveys of the distribution of holothurians were conducted on 2 inshore reefs (Pandora and Phillips), 2 mid-shelf reefs (John Brewer and Rib) and two outer-shelf reefs (Myrmidon and Dip) during September/October 1982.On the inshore reefs a single reef zone was examined. For mid-shelf and outer-shelf reefs, three zones were sampled; the outer reef flat, the inner reef flat and the leeward bommies.Surveys were carried out at night at depths of Holothuria atra, Holothuria axiologa, Holothuria coluber, Holothuria difficilis, Holothuria edulis, Holothuria hilla, Holothuria impatiens, Holothuria leucospilota, Holothuria nobilis, Actinopyga lecanora, Actinopyga mauritiana, Actinopyga miliaris, Actinopyga obesa, Actinopyga serratidens, Stichopus chloronotus, Stichopus variegatus, Stichopus sp.1, Stichopus sp.2, Bohadachia argus, Bohadachia graeffei, Bohadachia marmorata, Thelenota anax, Euapta godeffroyi.Additional species identified adjacent to belt transects:Holothuria fuscocinerea, Holothuria paradalis, Stichopus horrens, Actinopyga echinites, Synaptula maculata, Thelenota ananas.

1982年9月至10月，研究团队对6座珊瑚礁开展了海参类（Holothurians）分布调查，涵盖2座近岸珊瑚礁（潘多拉礁（Pandora）与菲利普斯礁（Phillips））、2座陆架中部珊瑚礁（约翰·布鲁尔礁（John Brewer）与里布礁（Rib））以及2座陆架外缘珊瑚礁（米尔米顿礁（Myrmidon）与迪普礁（Dip））。近岸珊瑚礁仅对单个礁区进行了调查；陆架中部与陆架外缘珊瑚礁则分别取样了3个礁区：外礁坪、内礁坪以及背风突礁（bommies）。本次调查于夜间开展，共调查以下海参类物种：黑海参（Holothuria atra）、轴纹海参（Holothuria axiologa）、瘦海参（Holothuria coluber）、困难海参（Holothuria difficilis）、紫轮参（Holothuria edulis）、希拉海参（Holothuria hilla）、不耐海参（Holothuria impatiens）、白斑海参（Holothuria leucospilota）、高贵海参（Holothuria nobilis）、莱氏辐肛参（Actinopyga lecanora）、毛利辐肛参（Actinopyga mauritiana）、密足辐肛参（Actinopyga miliaris）、肥胖辐肛参（Actinopyga obesa）、锯齿辐肛参（Actinopyga serratidens）、绿刺参（Stichopus chloronotus）、杂色刺参（Stichopus variegatus）、刺参属未定种1（Stichopus sp.1）、刺参属未定种2（Stichopus sp.2）、斑玉足海参（Bohadachia argus）、格雷费玉足海参（Bohadachia graeffei）、大理石玉足海参（Bohadachia marmorata）、巨梅花参（Thelenota anax）、葛氏锚海参（Euapta godeffroyi）。此外，在带状样带周边还额外记录到以下物种：棕斑海参（Holothuria fuscocinerea）、帕拉迪斯海参（Holothuria paradalis）、霍氏刺参（Stichopus horrens）、棘辐肛参（Actinopyga echinites）、斑指参（Synaptula maculata）、梅花参（Thelenota ananas）
