Which of these is NOT an adaptive features for arboreal life?

The feature that is NOT an adaptive feature for arboreal life is possession of teeth. Arboreal animals are those that live in trees, and they need to be adapted to this lifestyle to survive. Possession of a long tail helps animals maintain balance while moving through the branches. Possession of claws is also important for gripping onto branches and climbing trees. Counter shading in coat colour helps to camouflage animals from predators while they move through the trees. However, possession of teeth is not a unique adaptation to arboreal life. Most animals, regardless of their habitat, have teeth for feeding and survival. Therefore, possession of teeth is not an adaptive feature that specifically helps animals survive in arboreal environments.
