Its exoskeleton, or 'armour'. A new one has already grown underneath it as molting begins, and only needs some time to harden out afterwards.
Arrow crabs have 5 pairs of legs and can regenerate any of them when it molts and sheds it's exoskeleton although it may take several molts to completely regenerate it.
Molting
Some arthropods do molt after reaching maturity. However, most arthropod species only molt before adulthood is reached and not afterward. King crabs are an example of an arthropod that still molts occasionally after reaching maturity.
If an animal sheds its skin it will have a new clean layer already prepared underneath and if the old one comes away cleanly then it will remain in one piece.

NO Mammals are not arthropods. Arthropods are insects.
As it molts, it will grow. :)
