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.
What else can I help you with?
Do spiders have an exoskeleton?
Yes, spiders have an exoskeleton, which is a hard, external covering that provides support and protection for their bodies. This exoskeleton is made of a tough protein called chitin and must be shed periodically as the spider grows.
How do spiders shed their skin?
Spiders shed their exoskeleton through a process called molting. They produce a new, soft exoskeleton under their old one, then they split open the old exoskeleton and crawl out of it. The new exoskeleton will harden and provide room for the spider to grow.
How many bones does a spider have in it's body?
Spiders do not have bones. Instead, they have an external structure called an exoskeleton made of a substance called chitin. This exoskeleton provides support and protection for the spider's body.
Do spiders have external plates?
No, spiders do not have external plates. Their bodies are divided into two main parts: the cephalothorax (head and thorax combined) and the abdomen, which are covered by a tough exoskeleton made of chitin.
Does a spider have endoskeleton or exoskeleton?

Does a spider have vertebrae?
Spider do not have backbones; spiders have an exoskeleton (their bodies are supported by the outer shell of their bodies which is made of chitin).

Arthropoda is the phylum characterized by having an exoskeleton made of chitin. This phylum includes animals such as insects, spiders, and crustaceans.
Do spiders have spiracles?
NO. Spiders, insects etc. do not have an internal skeleton. They have an exoskeleton.
