A deep-sea isopod Bathyopsurus nybelini adapted to feed submerged Sargassum algae

NEWS - Incredible footage shows a marine species, Bathyopsurus nybelini , feeding on something that sinks from the ocean’s surface. Researchers using the submersible Alvin found the isopod swimming 3.7 miles down using its paddle-like legs to catch an unexpected food source: Sargassum. Researchers from Woods Hole Oceanographic Institution (WHOI), the University of Montana, SUNY Geneseo, Willamette University and the University of Rhode Island found the algae sinking, while the isopod waited and adapted specifically to find and feed on the sinking nutrient source. The Sargassum lives on the surface for photosynthesis. The discovery of a deep-sea animal that relies on food that sinks from the waters miles above underscores the close relationship between the surface and the deep. “It’s fascinating to see this beautiful animal actively interacting with sargassum, so deep in the ocean. This isopod is extremely rare; only a handful of specimens were collected during the groundbreaking Swedis...
