And I just seem to be finding all kinds of goodies...

JackG is correct, Japanese Jiujitsu and Brazilian Jiujitsu are very different arts. Japanese jiujitsu is a broader in scope while Brazilian jiujitsu is more grappling and submission oriented. People now, because of it's popularity, automatically assume that jiujitsu = groundfighting and that's not always the case.

As for the biting:

The examples given of someone going for a submission, let's stick with the triangle, and the other person bites them is perfect. As a BJJ guy, I have gotten very used to not striking during sparring. If I was going with someone and managed to slip on a triangle, I would continue that mentality:

I would not be trowing strikes.

Now let's say that person bit me.

You better believe I would rain down a barrage of elbows to the exposed face of my opponent who has nearly no ability to protect his face (ala Anderson Silva vs Travis Lutter).

If I had an armbar and you bit me, I would completely break your arm before letting go of the armbar.

If I was on your back and I was going for a choke and you bit me, I would rain down elbows to the back of your head and neck.

If I was mounted on you and you bit me I would present more elbows to your face.

If I was in side control and you bit me I would drop knees on your face.

I hope this answers your question.

If anyone wants to try sparring with someone adept at BJJ and seeing if biting works feel free to stop by my school anytime. I will have a waiver for you to sign, though.
