The Polychaete Worm

This image is an electron micrograph of a tiny, 2mm long worm.

Honest, this little chap really does look like that.

But what on earth would it look like if he was enlarged to a larger size?

How would it be if it evolved to take over the world?

… and what if it was a much larger size still? … and is there any video of it? well, follow this link.
