There are a variety of unique fish on the ocean floor that are rarely exposed. One of them is this fish where the head is transparent. Like what?
The fish sometimes appear in the deep waters of the California area. Known as a barreley fish, it was captured by an underwater device operated by the Monterey Bay Aquarium Research Institute (MBARI).
"This MBARI remote vehicle has successfully dived 5,600 times and recorded more than 27,600 hours of video, but we have only passed this fish nine times," the video description reads.
This fish has two eyes on its face, but actually, its eyes are on the top of its transparent head. His eyes glowed green which further emphasized his uniqueness.
The barreley fish's eyes are in that position so that it can freely see the food that is above its head, because its habitat is in a very deep sea.
This fish was first detected in 1939. The translucent and glowing part of its head contrasts with its dark body.
According to evolutionary experts, the fish developed strong eyesight to adapt to its harsh environment, where even sunlight cannot reach the area.
Their eyes are similar to the eyes of animals whose habitat is in the deep ocean area, with large lenses and layered retinas, allowing them to detect maximum light.
In research by scientists in 2019, it was found that the fish can rotate so that in addition to looking ahead, it can also look up.
The appearance of the fish passing by near the underwater vehicle that recorded its presence.
