Many vertebrates have pairs of what attached to their trunks?

Many vertebrates have pairs of limbs attached to their trunks. These limbs can be forelimbs (such as arms or wings) and hindlimbs (such as legs), and they serve various functions including locomotion, grasping, and manipulation of objects. The structure and function of these limbs can vary widely among different species, adapted to their specific environments and lifestyles.
