325:, use their tails for traveling and usually never use their forelimbs for transportation, while some species use both their tails and forelimbs. Suspensory behavior is advantageous for avoiding predators. The quick motions and ability to escape high above the ground enables an avoidance strategy, maintaining survival. While this type of locomotion can be beneficial there can be some consequences when dealing with extreme heights as vigorously moving through the trees allows for more opportunity for injury. The easiest way for animals to avoid this consequence is using their abilities to focus on uninterrupted travel, accuracy and avoiding alternative routes.

435:. Hanging by the tail is very common when foraging which permits the use of the hands and arms to not only grab food but to catch themselves if they were to slip or fall. Suspension allows for fast travel, which is helpful when collecting food as well. Speed allows animals to minimize competition while avoiding predators to ensure they grab as much food as they can in a short period of time. If an animal is in a high tree, they often eat their food then and there to avoid injury and predators.

Primates and sloths are most commonly seen using these behaviours, however, other animals such as bats may be seen hanging below surfaces to obtain food or when resting.

Animals use this type of behavior when crossing between trees and other surfaces. This movement requires the use of the hind limbs to leap across extended areas. Small animals have an easier time leaping between gaps, while larger animals are more cautious due to their weight and typically swing from

Forelimb-suspend/sit: This is similar to sit/forelimb-suspend except more than half the weight is held by the forelimbs and not the ishchia.
