Description
Definition Intertidal or Subtidal areas dominated by burrowing or construction activities of larger (megafaunal) organisms that create a water-filled tunnel with a diameter of > 1 centimeter. Tunneling activities are often attributable to crustaceans (generally decapods), but fishes (e.g., tilefish) and other taxa may also create large tunnel features. An associated mound of sediment may also be constructed. This biotic group is usually identified by the presence of tunnels or structures; the actual animal may be difficult to locate.
