What maximum running speed are some whiptail species capable of attaining, often using bipedal locomotion?

Answer

24 mph

Whiptails rely heavily on extreme speed as their primary defense mechanism against predators such as hawks, coyotes, and leopard lizards. Their locomotion is energetic, often exhibiting a characteristic jerky, start-stop motion, especially when moving under cover. When needing maximum velocity, they have been observed running upright on only their hind legs to gain an advantage in speed or visibility. The text indicates that some species possess the capability to reach speeds as high as 17 mph, with some estimates extending this capability up to a maximum of 24 mph.
