The exoskeleton is made of several layers of cuticle, a composite material containing various proteins and chitin, a long-chain polysaccharide (sugar). The chitin and protein molecules are arranged in long chains, in successive layers, like the grain in plywood. This structure makes cuticle extremely strong, as well as highly effective at keeping the spider from drying out, but the material does have one serious drawback. While it's flexible enough for movement, it can't expand like human bones and tissue -- in other words, it can't grow. In order to increase its size, the spider has to form a new, larger cuticle exoskeleton and shed its old one (this is called molting). Molting occurs frequently when a spider is young, and some Spiders may continue to molt throughout their life. At the appropriate time, hormones tell the spider's body to absorb some of the lower cuticle layer in the exoskeleton and begin secreting cuticle material to form the new exoskeleton. The new exoskeleton is typically folded to some extent, so it can expand once the spider sheds the older one. The spider also secretes a molting fluid between the old exoskeleton and the new one. Once the new exoskeleton is finished, the spider absorbs the molting fluid. This creates a gap between the two exoskeletons, which makes it easier to separate them.

Do spiders have an exoskeleton?
Yes. They're fairly similar to crabs and shellfish in that matter. No skeleton but a rigid hinged "skin" instead.
Does a spider have an internal skeleton or an exoskeleton?
Yes, you can see it particularly on small dead spiders, they go kind of transparent.
Why do spiders turn white?
Spiders turn white when their body stops receiving blood flow. The exoskeleton that appears white after the spider dies is called the chitin.
Does a spider have endoskeleton or exoskeleton?
Spiders have exoskeletons and also a small endoskeleton of plates made of a cartilage-like material.Spiders have exoskeletons and also a small endoskeleton of plates made of a cartilage-like material.

Arthropod is any creature that has an exoskeleton. Arachnid refines that classification to include only Spiders.

Do arachnids have bones?
Spiders have an exo skeleton, their "bones" are on the outside. No. they would not have a spine. although when some spiders molt, or shed their skin, and old exoskeleton. This enables them to grow.

What is the outer covering of a mosquito?
Mosquito have a hard outer shell, similar to many other species of insects. This shell protecting and armoring their bodies is known as an "exoskeleton." Exo is the prefix regarding exterior or outside.
What organisim is a arthropod?
An arthropod is an organism characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. Examples include spiders, millipedes, lobsters, crabs.
