ROV surveys: a total of 48 video transects (duration: 9 h 9 min 26 sec) were used, looking for benthic and pelagic sea cucumbers. Snapshots were taken for each sea cucumber, registered coordinates and depth and identified them to the lowest possible taxonomic level. Towed camera images: A total of 5,066 photographs, looking for benthic and pelagic sea cucumbers were analyzed. For each sea cucumber, coordinates and depth were registered and identified to the lowest possible taxonomic level.
Southern Colombian Caribbean
Survey areas of interest were assessed using 25 towed camera transects. These transects registered seafloor features, during 3-hour surveys, taking still images every 20 seconds. Benthic and pelagic megafauna specimens were recorded in the images.
Videos were analysed twice for the presence of cnidarians by two different experts. This methodology allowed us to ensure all cnidarians were registered. Still images and pictures of towed camera were analysed twice by the same expert, who did preliminary identification to phylum and class. All sea cucumber images were then identified to the lowest possible. When in doubt about the identification, additional experts were contacted and the images were sent to them in jpg format for towed camera photographs, and as a snapshot (also in jpg format) for ROV videos.

in the frame of the Oil & gas exploration, towed camera pictures and ROV transects were done, in which deep sea fauna was encountered and identified by national and international experts, contributing to new knowledge about deep sea fauna in the Colombian Caribbean

Colombian deep seafloor are basically soft muddy bottoms
25 towed camera trasects of about 3 hours each, taking pictures every 20 seconds in 4 survey areas. ROV video surveys in a cross pattern from a central point around 80-100 meters north, south, east, west.
