南美洲南部迭戈拉米雷斯群岛（智利南部）附近发现了8种新的食肉海绵动物：这些海绵大多来自海底渔业偶然采集的一种抗病珊瑚，其中大部分来自深海渔业偶然采集的一种抗病珊瑚，其中大部分来自深海渔业偶然采集的一种抗病珊瑚。这表明该地区食肉海绵的多样性和丰富性出乎意料。本文讨论了Cladorhizidae科的分类学和生物地理学，重点讨论了Abyssocladia的cladorhizid和phelloderid的亲缘关系，并讨论了该属中可能存在闭锁螯或弓形螯作为唯一螯形态的物种。本文综合了枝杆纲的地理分布和水深分布。
Eight new species of carnivorous sponges are described from southern South America, off Diego Ramirez Archipelago (south Chile): Abyssocladia diegoramirezensis, sp. nov., A. umbellata, sp. nov., Asbestopluma (Asbestopluma) bitrichela, sp. nov., A. (A.) magnifica, sp. nov., A. (A.) microstrongyla, sp. nov., A. (Helophloeina) delicata, sp. nov., Chondrocladia (Chondrocladia) schlatteri, sp. nov. and C. (Meliiderma) latrunculioides, sp. nov. Most of these sponges were sampled from an antipatharian coral collected accidentaly by demersal fisheries, which indicates an unexpected high diversity and abundance of carnivorous sponges in this area. The taxonomy and biogeography of the family Cladorhizidae is discussed, with an emphasis on cladorhizid versus phellodermid affinities of Abyssocladia, and on the possibility that species bearing either cleistochelae or arcuate chelae as the sole chelae morphotype may belong in this genus. A synthesis of the geographic as well as bathymetric distribution of cladorhizids is presented.
