Something very freaky is lurking in the deep waters off the California coast.
Researchers aboard a deep sea vessel spotted a barreleye fish and captured the rare sighting on video.
The bizarre-looking fish can see through its own forehead.
It grows up to 6 inches long and lives at a depth of roughly 2,000 feet.
The fish can rotate its eyes upward to see through transparent tissue on its head. This allows it to stealthily track its prey from below.
