Deep­ Sea fishes (Chondrichthyes, Osteichthyes) in the Southwestern Colombian Caribbean

Interest in the deep seas has increased dramatically in the last decade, due to the potential presence of natural resources. Although Colombia holds a large submerged territory, knowledge of the seabed and its biodiversity beyond a depth of 1000 meters is very limited. During 2015-2017, Anadarko Colombia Company (ACC) carried out hydrocarbon exploratory activities in the Southern Colombian Caribbean, at depths between 375 m and 2500 m. As an opportunistic result from these activities,
several organisms from different phyla were spotted in ROV and towed camera surveys. We analysed a total of 9h 9min 26sec of video and 5066 photographs, looking for benthic and pelagic megafauna. The images were separated by Phylum and Class, and the fishes were identied to the lowest possible taxonomic level. The data presented here corresponds to 250 occurrences of deep-sea fishes and 190 were identified from order to species. This is the first of a series of datasets reporting visual confirmations on the occurrences of deepsea organisms in the Colombian Caribbean.

近十年来，对深海的兴趣急剧增长，这主要归因于其中可能存在的自然资源。尽管哥伦比亚拥有广阔的海底领土，但对其1000米深度以下的海底及其生物多样性的了解极为有限。在2015至2017年间，安纳多克哥伦比亚公司（Anadarko Colombia Company，简称ACC）在哥伦比亚南部的加勒比海区域进行了烃类勘探活动，活动深度介于375米至2500米之间。作为这些活动的偶然成果，ROV和牵引摄像机调查中发现了来自不同门类的多种生物。我们对共计9小时9分钟26秒的视频和5066张照片进行了分析，寻找海底和浮游巨无霸生物。图像根据门和纲进行了分类，鱼类被识别到最低的税onomical级别。此处呈现的数据涉及250次深海鱼类出现的记录，其中190种从目到种都被识别出来。这是系列数据集的第一部分，旨在报告哥伦比亚加勒比海区域深海生物出现的视觉确认。
