but first guess would be a speck judging by the banding. It would be helpful to see the whole animal.
As for the possibility of a hybrid speck x tigris I don't doubt it's possible. Judging by the fact that they occupy very similar biological niche's and that they do exist together in many ranges in AZ, it would be very possible. Wether or not it has, I don't know for sure but I'd love to see pics if someone has em.
I'm still waiting on the pics of the speck/tiger or whatever it might be.
