Imagine what it would be if you stripped your goldfish off its lovely scales and got almost-anatomical-almost-fossil-like fins. It sure does look ugly and resembles a lab mouse to a great extent. Well, it’s some experience to see the insides of a fish as it moves about. Yet, it’s still all fleshy inside. May be the guys at Japan’s Mie University enjoy muscles of goldfish, moving underwater.

Whales would be a better option. Their bodies are hollower and you could spot a prophet or two inside.
