This invention relates to the field of biomimetic teaching aids, and proposes a quadrupedal vertebrate biomimetic teaching aid, comprising a spine unit, a tail component, and a head component. The spine unit includes a connecting plate, a rotating plate, rotating rods, and connecting shafts. The two ends of the rotating rods are rotatably connected to the connecting plate and the rotating plate, respectively.
