Well I have noticed that black nosed tegus have small heads or atleast thats what my tegu seems to be like now and what the pictures of varnyards black nosed tegus look like too. Im not saying that its a bad thing I personally like it. What ive seen some are not like that. Some tegus of the jam/whitey clutch seem to have rather large heads, give me your thoughts on this topic. Like I said this isnt a bad thing I really like the way it looks and it makes them stand out.
