Reptilia, Aves and Mammalia · Zoology

The skin of reptiles is primarily adapted to:

  1. Facilitate cutaneous (skin) respiration
  2. Prevent water loss
  3. Enable thermoregulation through sweat glands
  4. Serve as the primary site of gas exchange
Show answer and explanation

Correct answer: Prevent water loss

Reptilian skin is dry and covered with keratinised scales that form a barrier reducing trans-epidermal water loss. This waterproofing is essential for survival in terrestrial and arid habitats.
