The Monterey Bay Aquarium Research Institute has published a new video, in frames – a smallmouth macropinna.

At a depth of hundreds of meters in Monterey Bay off the coast of California, USA, scientists have captured a fish with a convex translucent head and green ball eyes. A strange animal looks at the world through its forehead.

This bizarre creature, known as the Macropinna microstoma, is very rare. Scientists at the Monterey Bay Aquarium Research Institute (MBARI) have seen this fish only nine times. At the same time, remotely operated vehicles (ROV) have already completed 5,600 observation dives. But last week, a group of researchers still saw the smallmouth macropinn.

At the time, the ROV was cruising at a depth of about 650m in the Monterey Bay Underwater Canyon, one of the deepest places on the Pacific coast, Thomas Knowles, a senior scientist at the Monterey Bay Aquarium, told Live.

Smallmouth macropinn, or barrel-eye, is a species of deep-sea ray-finned fish, the only representative of the genus Macropinn from the opisthoproctaceous family. They have a transparent head through which they can see with their tubular eyes. The head through which the fish follows the prey helps to protect the eyes. The habitat of this fish extends from the Bering Sea to Japan and Baja California. She lives at a depth of 200 to 1000 m under water.
