What does Spider mean?
A spider is an eight-legged arachnid that makes silk.
Dictionary definition
A spider is an eight-legged arachnid in the order Araneae. All spiders make silk for uses such as egg cases, safety lines, shelters, or prey-catching webs, but not every spider builds a web to catch food. Spider can also name some objects with radiating legs or arms, though that sense is specialized.
