Question

Arboreal mammals have
A. Running character
B. Burrowing character
C. Climbing character
D. Flying character

Answer 1

Hint: Arboreal species tend to possess an occasional centre of mass to cut back the probability of falling. Most arboreal mammals extend their limbs any forward and backwards throughout the movement, taking longer steps than their non-arboreal counterparts.

Complete answer: Limbs and Tails
Many arboreal animals have elongated limbs modified to swing with efficiency from branch to branch. Several monkey species show this anatomical adaptation. Many creatures have long tails as prehensile tails which may grasp branches and act as an additional limb. Spider monkeys, possums and chameleons use their tails to assist and move from tree to tree. Therefore, arboreal mammals have the ability to climb.
i. Feet and Claws: It is necessary that animals living in trees have a good grip. Some arboreal animals like squirrels have a synovial joint that helps the foot to move backwards. Claws are used as a hook into the tree bark once they come down from the tree. Several arboreal animals have claws to grip into the trees, whereas others have adhesive pads, like tree frogs and geckos. Primates have bald fingertips and chameleons have mitten-like feet to move on branches.
ii. Movement: Moving through trees is totally a different challenge. Arboreal species tend to possess an occasional centre of mass to cut back the probability of falling, and a few have a huddled posture. They have a bent that provides them with a diagonal sequence gait to maximise balance. Most arboreal mammals extend their limbs forward and backwards throughout the movement, taking longer steps than their non-arboreal counterparts.
Hence, the correct answer is option C.

Note: Small size provides many advantages to arboreal species: such as increasing the relative size of branches to the animal, lower centre of mass, increased stability, lower mass (allowing movement on smaller branches), and the ability to move through the more cluttered habitat.
