is that a python? I was bitten by a python once, a small one. they have backwards facing razor sharp teeth. After it let go, I looked at my finger and could see the horseshoe of razor holes. I squeezed my finger, and the blood poured through profusely. the anticoagulate in the snake's saliva caused me to bleed freely. it was pretty cool. I wasn't seriously hurt, and I thought it was amazing to see that.
just a random thought.
