Corner Rise Seamounts
Geographical referenceNorthwest Atlantic
Area TypeSeamount closure (NAFO)
Closed since 2007-01-01
Habitat and BiologyGeneral BiologyPristine coral areas have been documented in five  of the Corner Rise Seamounts using remote operated vehicles.

Splendid alfonsino (Beryx splendens) is the most abundant deep-sea fish species found in these seamounts. This species  appears to aggregate near certain seamounts. Other fishes found include, for example, Cardinal fish (Epigonus telescopus) a slow growing and long-lived species.  Kukenthal Peak and, more generally, the western portion of the Corner Rise have been shown to be areas of high fish species diversity and abundance compared to other parts of the Corner Rise Seamounts. In addition to alfonsino, other fish species include black scabbardfish (Aphanopus carbo), and wreckfish (Polyprion americanus).
Physical description of the environment: SeamountsSC 2007: Consists of 19 peaks with some summits being only 800-900 m deep.

The Corner Rise seamounts are the shallowest seamounts in the New England – Corner Rise Seamount system, rising from the sea floor to approximately 1000 m depth or higher and cover approximately 1270 km2 in area from peaks above 2000 m depth. This hotspot, referred to as the “New England hotspot”, is more than 3000-km-long. A pause in volcanism 83 million years ago is responsible for the present day spatial gap between these two seamount chains. Named seamounts within the Corner Rise Seamount chain include: Bean Seamount, Caloosahatchee Seamount with Milne-Edwards Peak, Verrill Peak, Castle Rock Seamount, Corner Seamount with Goode Peak and Kukenthal Peak, Justus Seamount, MacGregor Seamount, Rockaway Seamount, Yakutat Seamount. Some of these peaks fall outside of the NAFO convention area.
