Abstract

A dense aggregation of skate egg cases was imaged during a photographic survey of the sea floor along the western Antarctic Peninsula in November 2013. Egg cases were noted in a narrow band between 394 and 443 m depth. Although some skate species in other oceans are known to utilize restricted areas to deposit eggs in great numbers, such nurseries have not been described in the Southern Ocean.

摘要

2013年11月，在对南极半岛西部海底进行的一次摄影调查中，拍摄到了密集聚集的鳐鱼卵鞘。在深度为394至443米的狭窄区域发现了卵鞘。虽然已知其他海洋中的一些鳐鱼种类会利用特定区域大量产卵，但南大洋中尚未有此类繁殖地的相关描述。
