A sea floor of soft sediment covered in venus flytrap sea anenomes and other invertebrates such as brittle stars. Credit: NMFS/NOAA One of the more common seafloor habitats in the Gulf of Alaska is sand and mud. These soft sediment habitats are home to the venus flytrap sea anemone (Actinoscyphia aurelia) and other invertebrates such as this great armored brittle star (Stegophiura ponderosa). Many of the organisms in these habitats are passive suspension feeders that orient themselves into the current to capture passing organic particles as they drift by. Image courtesy of NMFS, NOAA.
