I've been thinking of this video since I stumbled onto it several months ago. It's about a lizard specie, if you can call it that, who's natural habitat is south Australia. They call it the sleepy lizard, but it's truer name ranges from shingleback to blue tongue. California has a similar reptile with the same stumpy kind of tail, except it's scaly body resembles a cob of corn more than shingles IMO. I don't know about the Shingleback being poisonous, but the Gilla Monster from southern California deserts is definitely venemous. Here's the direct link to the original website harboring the embedded video link above.
