How do barreleye fish survive?
In addition to their amazing “headgear,” barreleyes have a variety of other interesting adaptations to deep-sea life. Their large, flat fins allow them to remain nearly motionless in the water, and to maneuver very precisely (much like MBARI’s ROVs).

Are deep water fish see through?
Like other deep-sea fish with unusual physiologies, the transparent head of the barreleye is believed to be an adaptation that has allowed it to see into the dark depths of the ocean. Scientists believe that the green coloring helps the barreleye to filter out sunlight from the surface far above it.
Which of these are not actually fish?

Why do deep sea fish look weird?
The pressure at the bottom of the ocean is another factor in the weird appearance of the creatures there. Cartilage and low-density flesh that doesn’t collapse under high pressure is the rule, rather than bony skeletons that would snap.
What fish has a light on its head?
Few wonders of the sunless depths appear quite so ghoulish or improbable as anglerfish, creatures that dangle bioluminescent lures in front of needlelike teeth. They are fish that fish. Typically, the rod of flesh extending from the forehead glows at the tip.
How many eyes does a spookfish have?

How do spookfish eyes work?
The eyes of all other back-boned animals use a lens to divert the path of incoming light and focus it onto a specific point of the retina. But the spookfish’s downward-facing eye uses mirrors instead, forgoing a lens in favour of hundreds of tiny crystals that collect and focus light.
