已知海洋洞穴支持丰富的大型动物;然而，很少有研究集中在小型动物。海洋洞穴小型底栖动物缓步动物已在日本和地中海被报道，包括Actinarctus neretinus Grimaldi de Zio，D 'Addabbo Gallo，Morone De Lucia，Vaccarella和Grimaldi，1982年在澳大利亚海岸的鱼岩洞和吉姆岩洞被报道。这项研究是描述澳大利亚新南威尔士州海岸外两个海底洞穴中独特小型底栖动物的系列研究的第四项，描述了9个新种。从这两个洞穴中只收集到67个缓步动物，但它们包含了至少16个不同物种的高度多样性，这两个洞穴中的物种差异很大。该动物群包括9个节肢动物属：Actinarctus，Batillipes，Dipodarctus，Halechiniscus，Raiarctus，Styraconyx，Tanarctus，Tholoarctus和Wingstrandarctus。本文描述了澳大利亚东海岸沿着高能海滩的9个新种，其中包括1个斑科和8个盐海胆科：孤斑Batillipessolitariusnov. sp.，澳大利亚双足蛛Dipodarctus australiensis nov. sp苏氏双足蛛Dipodarctus susan nov. sp.

Marine caves are known to support a rich macrofauna; however, few studies have focused on meiofauna. Marine cave meiofaunal tardigrades have been reported from Japan and the Mediterranean Sea and a preliminary list of species including a redescription of Actinarctus neretinus Grimaldi de Zio, D'Addabbo Gallo, Morone De Lucia, Vaccarella and Grimaldi, 1982 was reported from Fish Rock Cave and Jim's Cave on the coast of Australia. This study is the fourth in a series describing the unique meiofauna in two Australian submarine caves located off the coast of New South Wales, describing nine new species.Only 67 tardigrades were collected from the two caves, yet these contained a high diversity of at least 16 different species which are quite different in the two caves. The fauna includes nine arthrotardigrade genera: Actinarctus, Batillipes, Dipodarctus, Halechiniscus, Raiarctus, Styraconyx, Tanarctus, Tholoarctus, and Wingstrandarctus. This fauna is different from that reported for the high energy beaches along the East Coast of Australia.We describe nine new species comprising a single batillipedid and eight halechiniscids: Batillipes solitarius nov. sp., Dipodarctus australiensis nov. sp., Dipodarctus susannae nov. sp., Raiarctus jesperi nov. sp., Raiarctus katrinae nov. sp., Tanarctus hirsutospinosus nov. sp., Tholoarctus oleseni nov. sp., Wingstrandarctus stinae nov. sp. and Wingstrandarctus unsculptus nov. sp.
