Centipede
The exoskeleton is segmented, with a pair of legs attached to each segment. The number of leg pairs is dependent on species and can range from anywhere in the 10s to the upper 100s. They are powered by striated muscle and are used for movement, digging/burrowing, and attacking prey. In some species, the rear-most ones have a pinching ability. Another exterior feature of centipedes is claws on the head which are used to grab prey and can inject poison.
The central body muscle of centipedes is all striated and attached to the exoskeleton. It supports rapid movement and provides strength for pushing the body into looser soil. The requirement for all muscle tissue to be protected by the exoskeleton comes with limits, however. As the exoskeleton does not grow with the rest of the body and has to be shed when too small through a process called molting, it limits the size to which centipedes can grow.
