Deep octopod habitat in the western North Atlantic characterized by Standard Ecological Classification from videos

Abstract Habitat characterization is important to assess fully the niches of different organisms. There is a large knowledge gap regarding habitat use by deep‐sea benthic incirrate octopods, partly due to their assumed preference for hard‐to‐sample rocky substrata. This study uses observations from...

Description
Summary:Abstract Habitat characterization is important to assess fully the niches of different organisms. There is a large knowledge gap regarding habitat use by deep‐sea benthic incirrate octopods, partly due to their assumed preference for hard‐to‐sample rocky substrata. This study uses observations from in situ videos recorded by remotely operated vehicles (ROVs) deployed from the NOAA Ship Okeanos Explorer and implements the Coastal and Marine Ecological Classification Standard (CMECS) to describe the habitat of three common species of bathyal incirrate octopods living in the western North Atlantic Ocean: Bathypolypus bairdii (Verrill 1873), Graneledone verrucosa (Verrill 1881), and Muusoctopus johnsonianus (Allcock, Strugnell, Ruggiero, & Collins 2006). Significant differences in species' preferences for geoform setting, depth, and substrate type were found. All three species are most likely to be observed by ROV in a submarine canyon and least likely to be seen on a seamount. B. bairdii was found shallower than G. verrucosa and M. johnsonianus. This is the first study of its kind using CMECS to classify the habitat of specific organisms as opposed to the habitat types in a specific area.
