Tasmanian devils are not known for their speed. They are relatively slow-moving animals. Their top speed is estimated to be around 8 to 15 miles per hour (13 to 24 kilometers per hour). While they are not built for speed, they have powerful jaws and are known for their strong bite, which they use for scavenging on carrion and hunting smaller prey. Their main mode of movement is often a slow, lumbering gait.
