integuments
Natural protective skins
Integuments are outer coverings or protective layers.
In biology, the integument is the skin and its associated structures—hair, nails, scales, feathers.
The term extends to any natural covering: seed coats, membranes, shells.
The integument protects the body from environmental damage.
The word is technical, appearing mainly in anatomy and botany.
