1. The hip region - pelvis and sacrum - of a monitor lizard (Varanus salvator). This shows “standard” arrangement of the pelvic bones. 2. The hip region - vertebrae, pelvis and hindlimbs - of a carpet python (Morelia spilota). Some snakes, including boas and pythons, still have remnants of their hindlimbs, as a hang-over from their limbed ancestors. 3. Skull of a python (Python amethystinus). These are large constricting snakes, which squeeze the life out of their prey. They can swallow whole prey much bigger than themselves. 4. Skull of a blindsnake (Typhlops lumbricalis). These are tiny snakes, which at first glance might be mistaken for worms, which live in burrows underground. 5. Skull of a flap necked chameleon (Chameleon dilepis) Models made in Avizo, from CT scan data, by Robert Brocklehurst.
