#41: The Freaky Fish With the See-through Head
The barreleye always looks up, through its own head, to find food.
The barreleye fish has eyes that gaze upward right through a transparent shield covering its head. This year ecologists at the Monterey Bay Aquarium Research Institute studied the first-ever underwater video of the strange fish. They also managed to recover one alive and get a good look at that shield, which may protect its eyes as it steals prey from stinging jellyfish.
