This photo comes from www.mongabay.com. It shows Dr. Tim Georoff, a vet at the Bronx Zoo (where Andrew and I were raised) x-raying a Gila monster to see if she’s with child (or in this case with a bunch of eggs).
Dr. Georoff has put the Gila monster into the Plexiglass box to protect himself from the reptile’s deadly, neurotoxic venom, found in the creature’s teeth and saliva. According to mongabay.com Gila monsters inject the venom into their pray “through grooves in the teeth of [their] lower jaw[s].”

Bombarding unborn, reptile babies with x-ray radiation, hmm……Isn’t that the first scene in Godzilla?
