There's an elusive fish that exists with a transparent head. Its eyes rest in the dome, protected, while those two dots that look like eyes above the Pacific barreleye fish's mouth are actually nostrils.
This is the first time the fish has been captured on video whole and in the wild. All other times, since the barreleye has been seen in the wild, it has been mangled in fishing nets, its head no longer inflated. Click here to watch the video.
