Like sharks, their bodies are not stiffened by bones, but by plates and bone-like bits of cartilage. But until the recent paper, it had not been officially identified anywhere in the Northern Hemisphere.Ĭhimaeras are unusual fishes. First named in 2002, it is known to live in deep waters around Australia, New Zealand, and New Caledonia. Scientists call this unusual fish Hydrolagus trolli, but its common name is the pointy-nosed blue chimaera. For example, one deep-sea fish that was previously identified in the Southeastern Pacific has recently been found around the Hawaiian Islands and off the coast of Central California, according to a new paper by MBARI researcher Lonny Lundsten and his colleagues. Because most deep-ocean waters are connected, many species of deep-sea animals have huge geographic ranges. The deep sea is the largest contiguous habitat on the earth, covering two thirds of the earth’s surface and averaging over 3.5 kilometers deep. trolli) was videotaped by MBARI’s remotely operated vehicle Tiburon near the summit of Davidson Seamount, off the coast of Central California at a depth of about 1,640 meters.
