Why This Deep-Sea Fish Has a Transparent Head

Описание: Why This Deep-Sea Fish Has a Transparent Head
For over 60 years, scientists had no idea what the Barreleye fish actually looked like. Every time they pulled one from the deep ocean, its most incredible feature was destroyed. It wasn't until 2004 that we discovered the truth: this fish has a completely transparent head filled with fluid, and its real eyes are glowing green orbs that rotate inside its skull.
In this video, you'll discover:

Why the Barreleye's transparent dome remained hidden for decades
The shocking truth about its "fake eyes" and where the real ones are
How it hunts like a military drone in total darkness
The jellyfish-stealing strategy that makes it one of the ocean's sneakiest predators

The Barreleye fish lives 600-800 meters deep in the ocean's Twilight Zone, where it hovers motionless, scanning for prey with tubular eyes that work like built-in night vision goggles. Its green-filtered eyes block out sunlight and detect bioluminescence, while its liquid-filled dome protects it from jellyfish stings as it steals their captured food.
This is one of the strangest creatures ever discovered in the deep sea, and we're only beginning to understand how it survives in one of Earth's most extreme environments.
