What is the significance of the large, strong forelimbs of certain reptiles?

Explanation:
Functional adaptation shows how anatomy supports behavior. Large, strong forelimbs in these reptiles are not for display or swimming; they serve real tasks. For animals like monitor lizards, powerful forelimbs and claws let them dig burrows for shelter, thermoregulation, and egg protection. They also provide leverage and grip to stabilize the body while climbing over uneven surfaces, giving the animal better balance and control. This direct link between limb strength and its practical uses explains why these forelimbs are so large.
