在印度-太平洋地区收集到了几种薄壳状和脆弱结构的海绵，并且已经证明，如果不借助电子显微镜，很难区分，更不用说识别了。本文重新描述了采自帕劳的Halisarca melana de Laubenfels，1954和H. Metabola de Laubenfels，1954年从马歇尔群岛的马朱罗环礁获得的新材料，强调野外特征，如生命中的着色，表面特征和光学显微镜可获得的组织学细节。利用相似的性状，本文报道了Halisarca，H. ferreus sp. nov.，来自坦桑尼亚桑给巴尔和H. cerebrum sp. nov.，来自帕劳，被认可和描述。另一属属于Demospongiae的一个不同的亚纲，也具有脆弱的结构和结壳生长形式;这是Oscarella，并且还描述了该属的两个新种，O。stillans sp. nov.和菲律宾的O. nigraviolacea sp. nov.，来自坦桑尼亚的奔巴岛
Several sponges with a thin encrusting form and of fragile construction have been collected in the Indo-Pacific, and have proved difficult to differentiate, let alone identify, without recourse to electron microscopy. Here we re-describe Halisarca melana de Laubenfels, 1954 from Palau, and H. metabola de Laubenfels, 1954 from Majuro Atoll in the Marshall Islands from new material, emphasising field characters such as coloration in life, surface features, and histological details accessible by light microscopy. Using similar characters two new species of Halisarca, H. ferreus sp. nov., from Zanzibar, Tanzania, and H. cerebrum sp. nov., from Palau, are recognised and described. Another genus belonging to a different subclass of Demospongiae also has fragile construction and encrusting growth form; this is Oscarella, and two new species of this genus are also described, O. stillans sp. nov. from the Philippines, and O. nigraviolacea sp. nov., from Pemba Island, Tanzania.
