A zoologist compares the claws of arboreal and terrestrial mammals. Which of these defines the structural difference primarily indicating their adaptation?
Suitability for climbing versus walking on flat ground
Arboreal (tree-dwelling) mammals typically have curved, sharp claws that are well suited for gripping bark and climbing trees.
Terrestrial mammals typically have straighter, blunter claws suited for walking and running on flat ground.
This structural difference is primarily an adaptation for climbing versus walking, not for defence or camouflage.
Hence, this is the correct answer.
