Several species of lizards are capable of bipedal locomotion, typically as a means to achieve higher running speeds. During this movement, the lizard runs on its long hind limbs while holding its tail out to act as a counterweight.12

Lizards known for this behavior include:

  • Basilisk lizards (Basiliscus): Found in tropical North and South America, these lizards are famous for their ability to run across the surface of water on their hind legs when frightened, a trait that has earned them the nickname "Jesus Christ" lizards.23
  • Frilled lizard (Chlamydosaurus kingii): Native to Australia and New Guinea, this lizard can run while standing on its hind legs with its forelegs and tail held in the air.214
  • Collared lizard (Crotaphytus collaris): This species, found in the United States, is also documented as being capable of bipedal movement.1

Because their center of gravity is located in front of the hips, these lizards must maintain continuous forward motion to keep their semi-erect posture while running.1
