Which of the following features characterizes the locomotion of spider monkeys?

The locomotion of spider monkeys is characterized by suspensory locomotion with a prehensile tail. This means that spider monkeys are adept at using their tails to grasp and hold onto branches, allowing them to move efficiently through the forest canopy. Their long limbs and flexible joints enable them to swing from branch to branch, using a combination of arm movement and their tails for balance and support. This type of locomotion is especially advantageous in arboreal (tree-dwelling) environments where spider monkeys primarily live, as it allows them to navigate their habitat quickly and effectively in search of food and mates.

In contrast, other forms of locomotion listed do not accurately represent spider monkeys' movements. Bipedal walking is primarily associated with humans and some other species but not spider monkeys. Quadrupedal movement may describe other primates or mammals that walk on all fours but does not apply to the brachiation style of spider monkeys. Vertical leaping is seen in certain other primates but is not a primary means of locomotion for spider monkeys, who rely more on their adaptations for hanging and swinging through trees. Thus, the focus on suspensory locomotion with a prehensile tail captures the unique adaptations that enable spider monkeys to thrive in
