In Zoology the invertebrate cuticula is a multi-layered structure outside of epidermis of many invertebrates, notably roundworms and arthropods, where it forms an exoskeleton. It is formed by fatty acids with alcohols other than glycerol.

In human anatomy, the cuticle refers to the fold of skin at the proximal end of the fingernail; see eponychium.
