* Humans: We are the most obvious example of a bipedal vertebrate.
* Birds: All birds are bipedal, although some can use their wings to help with balance or locomotion.
* Kangaroos: These marsupials use their powerful hind legs for hopping.
* Ostriches: These large flightless birds are also bipedal.
* Some dinosaurs: While dinosaurs are extinct, many species were bipedal, like the Tyrannosaurus Rex.
* Some lizards: Some lizards, like the basilisk lizard, are bipedal when running.
Keep in mind that there are many other animals with backbones that have more than two legs, or that have a mix of leg and limb types.
