The Nautilus is probably about 20cm in diameter. It swims backwards, by ejecting seawater through a ''hyponome'' - a fleshy tube. However, the hyponome is towards the base of the organism, well below its centre of gravity, so squirting out the water creates a jerky, rotating swimming action. Modern squid have the hyponome and centre of gravity 'in line', so they are much more efficient swimmers.
I wonder why its pupil is so dilated?

@aronchai they are mostly night feeders, and also tend to swim in deep water. They also have a primitive eye design.
