Uristes sp. length frequency data from the Molloy Deep

Concentrations of scavengers attracted by bait in the deep sea are documented by time-lapse photography and results of baited traps. During a remotely operated vehicle deployment in the Molloy Deep, the deepest depression of the Fram Strait, the carcass of a natant decapod, Pasiphaea tarda Krøyer, 1845, was discovered at 79°08.4'N and 002°49.85'E in a depth of 5,551 m. The carcass was covered by hundreds of individuals of Uristes sp., a scavenging lysianassoid amphipod. After documentation of this event, both the carcass and the majority of amphipods were collected. This is the first reported observation and sampling of an ongoing feeding process of scavengers on a natural food fall in the deep sea.

深海中由诱饵吸引的食腐动物浓度通过延时摄影和诱饵陷阱的结果进行了记录。在摩洛伊深海区域，即弗拉姆海峡的最深凹陷处，部署遥控潜水器期间，发现了一只浮游十足类动物，即克洛伊的帕西法厄亚（Pasiphaea tarda Krøyer, 1845）的尸体，位于北纬79°08.4'和东经002°49.85'，水深5,551米。尸体上覆盖了数百只乌里斯特斯属（Uristes sp.）的食腐丽虾类 amphipod。在记录这一事件之后，收集了尸体以及大部分 amphipod。这是首次报道在深海自然食物坠落过程中，食腐动物持续觅食过程的观察和采样。
