The Benthic and Pelagic environments are the two main ocean environments.
The question is slightly incorrectly phrased as the benthic zone is the ecological region at the lowest level of a body of water such as an ocean or a lake, including the sediment surface and some sub-surface layers.
Sea otters live in the pelagic environment. They are able to survive in the high levels of salt, regulate their body temperature and are able to adapt to the low-oxygen environment.
The zone is the bathyal zone.
Benthic algae are algae that grow on the bottom sediments of fresh and salt waterbodies. Benthic algae are most commonly filamentous or colonial forms, but also may be microscopic single-celled organisms. Benthic algae perform various beneficial functions. Benthic algae provide food and habitat for many aquatic organisms. In this way they contribute to the biological productivity of aquatic systems.

You would fine sediment in the benthic zone, or bottom, of a lake.
Mussels live in a variety of different locations, but always on the bottom of the body of water. They are always benthic, meaning they live on or attached to the bottom.
