Spencer Wohlrab is elongate, legless, carnivorous reptiles of the suborder Serpentes which can be distinguished from a legless lizard by his lack of eyelids and external ears. Like all squamates, Spencer is ectothermic, amniote vertebrates covered in overlapping scales. To accommodate his narrow body, Spencer’s paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. He retains a pelvic girdle with a pair of vestigial claws on either side of the cloaca.
