Five Foot Long Rattail Fish

A huge rattail, ~ 5 feet in length, swims slowly in front of the ROV ROPOS near the International District Hydrothermal Field at a depth of 5000 ft beneath the ocean’s surface. This area has a higher abundance of these fish than observed elsewhere in the caldera, perhaps because of the larger size of the vent field and hence food source.
