Transparent-headed Fish
Why Is It So Special?
The Transparent Headed Fish is an extremely rare species that lives in the deep ocean. Its most fascinating feature, which distinguishes it from other fish, is the transparent upper part of its head. This allows its eyes to be protected while enabling the fish to see its surroundings over a very wide angle.

What Does It Look Like?
There is a liquid-filled, glass-like dome on top of its head.
The green eyes inside the dome usually look upward, but turn forward when it spots prey.
The dark circular spots beside its eyes are not eyes but olfactory organs.
Its average length is 15 cm.
Where Does It Live?
It lives in the northern part of the Pacific Ocean, from Japan to California.
It is found at depths of 600–800 meters.
Because it lives in deep waters with very little light, its eyes have evolved special adaptations.
How Does It Move and What Does It Eat?
It generally remains motionless in the water, drifting slowly.
It looks upward to spot prey.
It feeds on zooplankton, small crustaceans, and other transparent organisms drifting in the ocean.
When it sees prey, it turns its eyes forward and swiftly captures it.

When Was It Discovered?
It was first described in 1939, but for a long time only dead specimens were known.
In 2004, its live form was first observed using specialized underwater robots.
This allowed scientists to learn how it swims and how it uses its eyes.
What Is Its Conservation Status?
There is no definitive information on its conservation status.
Because it lives in deep waters, it is not significantly affected by fishing.
However, human activities such as deep-sea mining and bottom trawling may threaten its habitat.
