How are the skeletal and muscular systems of amphibians adapted for life on land?

Amphibians have evolved skeletal and muscular adaptations that facilitate movement and support on land. Their limbs are robust and well-developed, allowing for efficient locomotion and weight-bearing, while their vertebral columns provide flexibility and stability. Additionally, their muscles are adapted for both swimming in water and walking or jumping on land, enabling a dual lifestyle. The combination of these adaptations helps amphibians navigate their terrestrial environment effectively.
