Rarely seen, bizarre-looking fish with transparent head spotted swimming in deep waters off CA coast

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.
