Okay so this may be old news, but I’ve never heard of these before. 😮 All species have large, telescoping eyes which dominate and protrude from the skull, but are enclosed within a large transparent dome of soft tissue. Blimey. Imagine having a transparent head. Aparantly this photo and the photage that was taken of this Barreleye fish was the first seen of the fish alive. All other evidence of it’s existence was from dead Barreleye that were caught up in fishing.
