The Macquarie Ridge is a major seafloor feature in the Southern Hemisphere between New Zealand and the Antarctic continent, and its marine communities have been poorly explored. During the MacRidge 2 TAN0803 survey conducted on board the R/V , several seamounts of the Macquarie Ridge were sampled. Among the benthic samples obtained, a collection of hydroids was present. Eleven species were recorded, including sp. nov., sp. nov. and sp. nov. Anthoathecata is represented only by sp. The collection is essentially dominated by Leptothecata, with ten species, belonging to the families Campanulariidae, Lafoeidae, Phylactothecidae, Plumulariidae and Sertularellidae. Lafoeidae is by far the most diversified family, accounting for half of the leptothecate species. At the generic level, the collection is dominated by the deep-water genus , with four species; all the remaining genera are represented by a single species. Seven species represent new records for the area and Watson, 2003 is recorded for the second time.
麦夸里海岭是南半球新西兰和南极大陆之间的一个主要海底地貌，其海洋群落尚未得到充分探索。在“麦夸里海岭2号”TAN0803航次中，“R/V”号船上对麦夸里海岭的几个海山进行了采样。在所获得的底栖生物样本中，有一批水螅虫类。记录了11个物种，包括新物种、新物种和新物种。花水母纲仅由物种代表。该样本主要由软水母纲组成，有10个物种，隶属于钟螅科、拉福螅科、叶螅科、羽螅科和小枝螅科。拉福螅科是迄今为止最多样化的科，占软水母纲物种的一半。在属的层面上，该样本以深水属为主，有4个物种；其余所有属均仅由一个物种代表。7个物种是该地区的新记录，并且于2003年第二次记录到了沃森氏物种。
