Question

Quizplus · Accepted Answer

Tetrapod skeletons, which include amphibians, reptiles, birds, and mammals, are modified for support on land. The limbs are more robust and have sturdy bones, and the attachment points for muscles are stronger to support the weight of the animal in gravity. This allows tetrapods to move and walk more effectively on land than aquatic animals.
