No, the rigid outer covering of arthropods is usually called the exoskeleton. In Biology the mantle is a major anatomical component of a different phylum - molluscs, the tissue which contains the internal organs and in many molluscs responsible for secreting the mineralized outer shell.
Crayfish are crustaceans, and therefore have a shell-like outer covering called an exoskeleton.
The exoskeleton.exoskeleton
It is called the exosketon. It is made from a hard protein, chitin, which arthropods often biomineralize for further strength.
The external covering on arthropods is called the exoskeleton (or cuticle). It is made of a tough protein called chitin, a long chain polymer comparable to cellulose. Because it's inflexible, arthropods need to shed it (moult) in order to grow.

The outer covering of the grain is called Husk.
Tonoplast is the outer covering of vacuole
The bodies of arthropods are supported by a hardened exoskeleton made of chitin, a substance produced by many non-arthropods as well. In arthropods, the nonliving exoskeleton is like a form-fitting suit of armor.
Endoskeleton
The outer covering of the grain is called Husk.
The outer covering of an apple is called the skin or peel.
