Explanation of Names
From Latin exuviae, "that which is stripped, drawn or taken off from the body, clothing, equipments, arms, etc." (see discussion).
Identification
exuviae noun (alt. exuvia, singular?), technically plural but often used as a singular - the cast-off exoskeleton ("skin") left over from a molt.
exuviate verb - to cast off a skin, to molt.
exuviation - the act of casting off a skin

Forms sometimes used are exuvium (singular) and exuvia plural are sometimes seen, but usage is not completely consistent. Gordh (1) lists exuvia as an alternative spelling (but does not state whether singular or plural) and states that exuvium is an incorrect singular form.

Remarks
The exuviae often maintain the shape of the creature they were shed from.
