NOAA’s Office of Ocean Exploration and Research has produced a collection of images photographed on-site, created from video frame grabs taken from Deep Discoverer (D2) remotely operated vehicle (ROV) video. Known as the Benthic Deepwater Animal Identification Guide, the resource serves as a taxonomic reference of deepwater animals encountered during D2 ROV dives around the Hawaiian Archipelago and Johnston Atoll during the Hohonu Moana expedition in 2015. The guide is organized according to major taxa, and identifications were made with assistance from taxonomic experts who specialize in deepwater animals. Species identifications will be periodically updated as errors are detected and reported by taxonomists and other users, or when taxonomic revisions are made to the various groups included in the guide. Taxonomic revisions are particularly common for deepwater animals, which are poorly known. Share the guide with high school biology students to help them see how science research is dynamic and changeable.
