How long does it take for a lobster to grow its limbs back?

Lobsters can regenerate lost limbs, but the time it takes varies depending on factors such as age, size, and environmental conditions. Generally, it can take anywhere from several months to a few years for a lobster to fully regrow a limb. The process involves multiple molts, during which the lobster sheds its exoskeleton and gradually develops the new limb. Younger lobsters tend to regenerate faster than older ones.
