The Skeletal System of Nematoda
The Nematoda Skeletal System contains cuticle outer covering that grants there body a definite shape, and is used for support and leverage point for movement. The thick outer cuticle is tough and flexible which provides Nematodas with its narrow shape. Its outer cuticle is shed four times in a Nematoda's life time before it reaches its adult age. A Nematoda's cuticle is usually secreted from its epidermis.

Loa loa
(Eye worm) Eye worms are tiny parasites that enter into the Human body by landing with flies and burrowing into the skin, and travels through the blood stream, eating the blood and ending up just below the surface, usually in the eye. Eye worms are very tiny and they don't have a skeleton. For support and to give resistance to the muscles they have fluid filled spaces forming a hydro-static skeleton.

Ascaris lumbricoides
(Roundworm) Roundworms do not have skeletons or ecto-skeletons. The space between the outside of the digestive system and the muscles and skin of the worms is filled with pressurized fluid. Like a long balloon, this space tends to "rebound" back to a set shape when bent, or it changes shape ways when squeezed, giving some resistance or direction to the action of the muscles. A muscle-resistance system based upon fluid-filled spaces is called a hydro-static skeleton.

Ancylostoma duodenale
(Hookworm) Hookworms are much smaller than the roundworms. Like all the other nematodes I used, the hookworm does not have a skeleton at all. It has a muscle structure and a hydro-static skeleton similar to the round worm. This means it has a muscle-resistance system based on fluid-filled spaces.
