Even if your crab is missing a claw and a couple of legs, it's likely you'll see them all start to grow back the next time he molts.

How long do crabs live for?

Crabs have an average lifespan of 3 to 5 years, with some species living up to 30 years. The average lifespan of a crab is between three to five years. However, this greatly depends on the species of the crab. There are many different crab species, and their age ranges all vary.

Do crab claws hurt?

Their sharp and strong grip can be quite painful, as anyone who has ever been pinched by one can confirm. And if threatened, a crab may break off claw or leg to try to escape predators; the limb will later regrow through a process called regeneration.

This is used as the rationale behind cooking them alive.

Can crabs breathe underwater?

Crabs breathe underwater by drawing water (which contains oxygen) over their gills using an appendage called a scaphognathite, which is located on the crab's underside, near the base of its claws. The water passes over the gills, which extract the oxygen.
