This research presents 17 new species of carnivorous sponges from the family Cladorhizidae sampled at bathyal and abyssal depths off the east coast of Australia during the RV Investigator 2017 Abyss Expedition. The species are comprised of six genera: Abyssocladia escheri sp. nov., A. annae sp. nov., A. gliscofila sp. nov., Asbestopluma (Asbestopluma) maxisigma sp. nov., Cladorhiza australis nov. sp., C. poritea sp. nov., C. investigator sp. nov., C. moniqueae sp. nov., C. pentaeiros sp. nov., Chondrocladia (Chondrocladia) freycinetensis sp. nov., Ch. (Ch.) callistemonex sp. nov., Ch. (Ch.) zygainadentonis sp. nov., Lycopodina nikitawimandi sp. nov., L. helios sp. nov., L. cassida sp. nov., L. brochidodroma sp. nov. and Euchelipluma claudochela sp. nov. Only three carnivorous species, A. desmophora, As. (As.) desmophora and C. (Meliiderma) tasmaniensis, have been recorded from Australia previously. This expedition also recovered two described species commonly recorded from the Southern Hemisphere Ch. (Ch.) clavata and L. calyx. This paper also redescribes two species from the South Pacific i.e. C. mirabilis and C. similis.
本研究展示了在2017年“调查者号”深渊探险期间于澳大利亚东海岸的深海和深渊深度采集的17种来自枝根海绵科的肉食性海绵新物种。这些物种分属于六个属：新物种埃氏深渊枝根海绵（Abyssocladia escheri sp. nov.）、安娜深渊枝根海绵（A. annae sp. nov.）、格利斯科菲拉深渊枝根海绵（A. gliscofila sp. nov.）、大西格玛石棉羽枝海绵（Asbestopluma (Asbestopluma) maxisigma sp. nov.）、澳大利亚枝根海绵（Cladorhiza australis nov. sp.）、多孔枝根海绵（C. poritea sp. nov.）、调查者枝根海绵（C. investigator sp. nov.）、莫妮克枝根海绵（C. moniqueae sp. nov.）、五角枝根海绵（C. pentaeiros sp. nov.）、弗雷西内半岛软骨枝根海绵（Chondrocladia (Chondrocladia) freycinetensis sp. nov.）、卡利斯特莫内克斯软骨枝根海绵（Ch. (Ch.) callistemonex sp. nov.）、齐盖纳登托尼斯软骨枝根海绵（Ch. (Ch.) zygainadentonis sp. nov.）、尼基塔维曼迪石松枝根海绵（Lycopodina nikitawimandi sp. nov.）、赫利俄斯石松枝根海绵（L. helios sp. nov.）、卡西达石松枝根海绵（L. cassida sp. nov.）、布罗基多德罗玛石松枝根海绵（L. brochidodroma sp. nov.）和克劳多切拉真唇海绵（Euchelipluma claudochela sp. nov.）。此前仅记录到三种肉食性物种，即德氏深渊枝根海绵（A. desmophora）、德氏石棉羽枝海绵（As. (As.) desmophora）和塔斯马尼亚枝根海绵（C. (Meliiderma) tasmaniensis）。此次探险还发现了两种常见于南半球的已描述物种，即棒状软骨枝根海绵（Ch. (Ch.) clavata）和花萼石松枝根海绵（L. calyx）。本文还重新描述了来自南太平洋的两个物种，即奇异枝根海绵（C. mirabilis）和相似枝根海绵（C. similis）。
