Why do Alligator Lizards always bite each other in the same spot while fighting?

I noticed while browsing @natureinla’s observations that Alligator Lizards always bite each other on the same spot on the head. Is that simply the most effective spot to bite, or is there some other reason?

Can you show an example?

I suppose the best way to not get bit by your opponent is to bite it in the head and hold on.

It’s a mating behavior. Some species are into that kind of thing.

Here are some examples,@jnstuart.

So these are copulating pairs or males attempting to copulate. As already mentioned, it’s mating behavior and presumably that grip is the most efficient for holding female in place to allow copulation. Might also make the female receptive to mating.
