Describe symbolism in The Cobweb by Raymond Carver

Public symbols have a range of associations accessible to many readers. Most Western readers understand, for example, that a rose can signify love, lust, passion, and beauty. Private symbols are often peculiar to a particular writer and so are not as accessible, especially for readers unfamiliar with that writer's work. Carver's spider web and the sea are public symbols. The cobweb is often associated with ideas of both creation (spinning a web) and death, how a spider traps its prey, while the sea has a wide range of symbolic associations, chief among them are ideas of life and death. The sea, like life, is constantly in flux, at once changing and the same. The ocean sustains much life and is often referred to as "the mother of life." To return to the sea is to return to the mother and to that which one was before life.
