Characteristics References

There are numerous submarine canyons extending from the Tohoku Coast. These canyons are home to many demersal fish. There are no large faults or fault zones on the continental plate and the continental slope from the area off the Sanriku Coast to that off the Joban Coast, other than those formed through the late Miocene period (Tokuyama et al., 2001). The Sanriku Escarpment (at depths of 5343–6809 m) is dominated by Calyptogena phaseoliformis and Calyptogena fossajaponica, and Acharax johnsoni, Retiskenea diploura, Bayerius arnoldi and others are found here as well (Fujikura et al., 2008).
