Introduction
The megapede is not comparable to any species on Earth. Its closest relative on Earth is the centipede. Its similarities with the centipede include a body with many segments (10) and asexuality.

History
The megapede has been around on Rocky X for nearly 50000000 (50 million) years. This species had close relatives called minipedes that lived about 80000000 (80 million) to 3000 (3 thousand) years ago that was much smaller. This species became extinct as a cause of the coolestcreature using its mucus covered skin as a water proof covering. Towards the beginning of its existence on Rocky X its population flourished because of the lack of other large carnivores because of a mass extinction. This mass extinction occurred about 60000000 (60 million) years ago, caused by a large meteor shower causing all species over 100 pounds to go extinct. But its current population is suffering now as a cause of the coolestcreatures starting to turn to the megapede for its skin as water proof covering and for some of its tissues inside for fuel as well as mutations causing other younger relatives of the megapede, such as the sinmucus and camopede, are much better off in defending themselves against the coolestcreatures.

Body Structure And Reproduction
The megapede has 3 senses (Or 4, whether you consider echolocation and hearing one or not). The megapede's 3 senses are taste, touch, and hearing/echolocation (they hear by using hairs to sense the incoming vibrations). The megapede has one opening for consuming, expelling waste, and breathing (it has a food pipe, an expulsion pipe, and a breathing/air pipe). The megapede is also asexual. And because of its single heart and single opening it can only reproduce 3 years after its previous split/reproduction because its opening, heart, and stomach needed to migrate to the middle of the megapede's body; this process takes about 3 years. The megapede is also segmented; it has 10 segments with 2 appendages per segment. The majority of its segments work like legs with the exception of the front 2, which work more like arms. The megapede also has bones. Its bones create a spine, food cage (an enclosed bone structure protecting the stomach, intestines, etc.), a lung cage (like the food cage but for the lungs (not the same as a rib cage)), a heart cage (like the food cage and the lung cage but for the heart), a brain cage (like the food cage, the lung cage, and the heart cage but for the brain (also has cushioning inside and outside the brain cage)(not the same as a skull)), a thick bone a near the outer edge of each segment, and for legs with one joint each. Contrary to the rest of the legs, the front legs have an extra (thicker and stronger) bone at the bottom (smaller ones than usual on top) to be able to dig. The megapede also has stronger muscles/tissues in the front legs than in the rest of the body. The megapede also has mucus covered skin.

Size
The megapede usually weighs 100-199 lbs, has a diameter of about 1.5 ft, and has a length of about 15 ft.

Young Megapedes
A newly split megapede weighs 50 lbs-99 lbs, is about 1.5 ft in diameter, and is about 7.5 ft long. A newly split megapede has a weaker layer of skin where it split; this makes it vulnerable to illness, poison, predators, and hard substances. Another reason the a newly split megapede is vulnerable is because of its outward facing opening; this makes it easy for falling objects as well as flying objects to enter its system. A newly split megapede also has some liquid leftover where it split. Then the newly split megapede finds a place with food and water and uses its liquid to moisturize some dirt so it can dig a cave. After the megapede finishes digging the cave it gets in the cave to protect itself from harmful substances. For about 1 year the megapede only re-exits the cave to get food and water.

Defensive Structures
The megapede has a hard shell.

Defensive Behaviors
The megapede camoflouges (the shell included). When a predator approaches the megapede the megapede will compress and elongate its body to reach a diameter of up to 3 times its original diameter (it also gets 9 times longer in this process) (a megapede's diameter usually changes from about 1.5 ft to 0.5 ft and its length usually changes from about 15 ft to about 135 ft) to fit into the nearest hole to hide. The way the megapede knows when a predator is approaching is with smell, and an interesting form of echolocation and hearing using hairs to sense the incoming vibrations.
