Critters

All the creatures of the field, forest, and jungle gotta eat.

So, too, our small friends the leeches. Imagine my surprise when I removed my boot and found a bloody sock.

Clever little evolutionists, the leeches have, in their saliva equivalent, both a local analgesic and an effective anti-coagulant. You don't know you are bit and you don't stop bleeding. Cool!
