Because taxidermy uses “derma” (skin) to create a lifelike replica, a preserved creature triggers deep emotions in us.
"skin beneath the epidermis," 1706, from Modern Latin derma, from Greek derma (genitive dermatos) "skin," from PIE root *der- "to split, peel, flay" (see tear (v.)).
derma der·ma (dûr'mə)n. See dermis.
-derma suff. Skin; skin disease: scleroderma.
