The anatomy of a spider, an arachnid, includes four pairs of legs and a body divided
into two regions, the cephalothorax and the abdomen.
The spider produces silk from
spinnerets located in its abdomen and uses the silk to spin webs, to line its burrow, to
wrap its eggs in cocoons, and to lower itself by a single strand to the ground. Its
scientific class, Arachnida, is named for the Greek tapestry weaver Arachne, who was
turned into a spider by the goddess Athena.
