These protective layers help provide waterproofing, insulation, and camouflage, as well as offer defense against predators.

Whether it is the skin of a human or the scales of a fish, the tegumentary features serve to shield, regulate, and provide defense to the organism, highlighting the importance of this adjective in the field of biology, anatomy, and zoology.
