Key Points: Desert Adaptations (Xerocoles)
| Adaptation Aspect | Structural / Physiological Feature | Purpose | Example / Group |
|---|---|---|---|
| Water conservation | Impervious skin; dry excreta (uric acid, guanine) | Minimises water loss | Reptiles, insects |
| Respiration | Invaginated spiracle system | Reduces evaporation | Desert insects |
| Food & water source | Feeding on dry seeds or succulent plants | No need for drinking water | Desert rodents, birds |
| Temperature avoidance | Burrowing; nocturnal activity | Escape heat | Rodents, reptiles |
| Locomotion on sand | Long limbs, padded feet | Easy movement on hot sand | Lizards, mammals |
| Protection & senses | Protective colouration, spines; keen senses | Defence and survival | Desert mammals, birds |
