Baby spiders pass all their larval stages inside the egg and hatch as spiderlings, very small and sexually immature but similar in shape to adults.
Some spiders care for their young, for example a wolf spider's brood cling to rough bristles on the mother's back, and females of some species respond to the "begging" behaviour of their young by giving them their prey, provided it is no longer struggling, or even regurgitate food.

Like other arthropods, spiders have to moult to grow as their cuticle ("skin") cannot stretch.
Most spiders live for only one to two years, although some tarantulas can live in captivity for over 20 years.ᵖ²³²
