Many species of animals, including humans and other mammals, have an internal support structure made up of bones. This endoskeleton can provide support for a wide range of different body shapes and sizes, and can grow smoothly with the animal it is inside of. Spiders, like all arthropods, lack an internal skeleton and ...

Like people, spiders move by contracting muscles attached to a skeleton. But instead of an internal skeleton covered in flesh, spiders have an exoskeleton-- a stiff support structure on the outside of the body. Exoskeleton segments are connected together with joints so the spider can move them back ...
Unlike most insects (some do) Spiders have exoskeletons and also a small endoskeleton of plates made of a cartilage-like material.
An exoskeleton (from Greek έξω, éxō "outer" and σκελετός, skeletós "skeleton") is the external skeleton that supports and protects an animal's body, in contrast to the internal skeleton (endoskeleton) of, for example, a human. In usage, some of the larger kinds of exoskeletons are known as "shells".
KidZone Spider Facts The Body of a Spider. Spiders have two body segments. The front segment is called the Cephalothorax. The spider’s eyes, mouth fangs, stomach, brain and the glands that make the poison are on this part of the body.
Spiders Molting Exoskeletons. Like other arthropods, spiders have a protective hard exoskeleton that is flexible enough for movement, but can’t expand like human skin. Thus, they have to shed, or molt, this exoskeleton periodically throughout their lives as they grow, and replace it with a new, larger exoskeleton.
The anatomy of spiders includes many characteristics shared with other arachnids.These characteristics include bodies divided into two tagmata (sections or segments), eight jointed legs, no wings or antennae, the presence of chelicerae and pedipalps, simple eyes, and an exoskeleton, which is periodically shed.. Spiders also have several adaptations that distinguish them from other arachnids.
The Spider Tank is one of Skynet's Non-Humanoid Hunter Killers as a principal ground-based combat robot. Spider Tanks are roughly two-and-a-half times the height of a human being. They are quadrapedal ground units of a similar design to the HK-Centurion. Spider Tanks have two arms, each with a...
The exoskeleton of spiders is composed of a tough material called cuticle. Cuticle is a composite material made up of a protein with microfibres of chitin embedded in it. Chitin is a polysaccharide. The microfibres are laid down in layers with the fibres in each layer having a slightly different orientation.
