All records of the 15 hexactinellid sponge species known to occur off Chile are reviewed, including the first record in the Southeastern Pacific of the genus Caulophacus Schulze, 1885, with the new species Caulophacus chilense sp. n. collected as bycatch in the deep water fisheries of the Patagonian toothfish Dissostichus eleginoides Smitt, 1898 off Caldera (27ºS), Region of Atacama, northern Chile. All Chilean hexactinellid species occur in bathyal to abyssal depths (from 256 up to 4142 m); nine of them are reported for the Sala y Gomez and Nazca Ridges, with one species each in the Juan Fernandez Archipelago and Easter Island. The Chilean hexactinellid fauna is still largely unknown, consisting of only 2.5 % of the known hexactinellid extant species. Further studies and deep water sampling are essential to assess their ecology and distribution, particularly in northern Chile.
对已知出现在智利海域的15种六放海绵纲物种的所有记录进行了综述，其中包括1885年舒尔策（Schulze）描述的Caulophacus属在东南太平洋的首次记录，以及新物种智利Caulophacus chilense sp. n.，该物种是在智利北部阿塔卡马地区卡尔德拉（27°S）附近巴塔哥尼亚齿鱼（Dissostichus eleginoides Smitt，1898）深水渔业的兼捕物中采集到的。所有智利六放海绵纲物种都出现在半深海到深渊深度（从256米到4142米）；其中9种在萨拉戈麦斯和纳斯卡海岭被报道，在胡安费尔南德斯群岛和复活节岛各有一种。智利的六放海绵纲动物群仍然很大程度上不为人知，仅占已知六放海绵纲现存物种的2.5%。进一步的研究和深水采样对于评估它们的生态和分布至关重要，特别是在智利北部。
