The Galapagos bullhead shark is not common around the Galapagos Archipelago. In the west it is located at the east and the north side of Fernandina Island and the west side of Isabela Island. This area is known as the Canal Bolivar. In the south part of Galapagos it is located only in Floreana Island and only at the west side of the island (upwelling area). This shark is associated with cold waters and where upwelling is strong (Rivera, unpubl. data).
