Drawing: Leech

I did a drawing today. I drew an animal today. I hope you enjoy this math. The animal I drew today is the leech. This is a very simple drawing. Now let's talk about 2/4 of this animal. These leech animals have flattened suckers on both sides of their bodies with which they suck blood. The upper part of their body is convex and the lower part is flat.
