Arboreal is a biological term describing an animal that lives in trees. Animals have always lived in the woods. These creatures have evolved characteristics that allow them to live and travel in trees. Suminia, a late Permian synapsid that lived around 260 million years ago, is the oldest known example.

Key Facts & Information

BIOMECHANICS

• Arboreal ecosystems present various mechanical problems to creatures moving through them, which have been addressed in multiple ways. 
• Moving on thin branches, traveling up and down inclines, balancing, traversing gaps, and coping with obstacles are all problems.
• Diameter: Animals have a tough time moving along a narrow surface. 
• The position of the center of mass may swing from side to side during terrestrial locomotion. 
• Still, during arboreal locomotion, this would result in the center of mass shifting beyond the edge of the branch, resulting in a tendency to tumble over. 
• Also, foot placement is limited due to the necessity to establish touch with the thin stem. This restriction substantially limits the range of motions and postures an animal can employ to move.
• Incline: Branches in arboreal ecosystems are commonly oriented at an angle to gravity, particularly vertically, which provides specific challenges. As an animal travels up an inclined stem, it must resist gravity to lift its body, making mobility more difficult. 
• In contrast, when the animal falls, it must battle gravity to regulate its descent and avoid falling. Many creatures struggle with slip, and highly arboreal species frequently have unique strategies for managing their fall.
• Balance: Owing to the height of numerous branches and the potentially deadly implications of a fall, arboreal animals place a premium on balance. 
• The fundamental issue with horizontal and mildly slanted branches is tipping to the side due to the short base of support. 
• The greater the difficulties in balancing certain animals encounter, the narrower the branch. 
• Tipping becomes less of a concern on steep and vertical branches, and pitching backward or sliding downwards becomes the most likely failure. 
• Large-diameter branches present a more significant problem because the animal cannot arrange its forelimbs closer to the middle of the branch than its hindlimbs.
• Crossing gaps: Because branches are not continuous, any arboreal mammal must be able to move between gaps in the branches, if not between trees.
• This can be done by reaching over gaps, leaping over, or gliding across them.
• Obstructions: Arboreal habitats are often obstructed by branches coming from the one being moved on and other branches intruding on the space through which the animal must pass. 
• These impediments may impair mobility or serve as extra touch points to improve it. Although obstacles restrict limbed animals, they help snakes by providing anchor points.

ANATOMICAL SPECIALTIES

• Arboreal species have several adaptations for dealing with mechanical obstacles while moving through their environments.
• Leg length: Arboreal animals commonly have lengthened limbs that aid in crossing gaps, reaching fruit or other resources, testing the strength of support ahead, and, in some cases, brachiating. 
• Yet, certain lizard species have smaller limbs that enable them to escape being impeded by impinging branches.
• Prehensile tails: Numerous arboreal animals have prehensile tails to hold branches, including tree porcupines, chameleons, silky anteaters, spider monkeys, and possums. 
• The tip of the tail of the spider monkey and crested gecko bears either a bare patch or an adhesive pad, which increases friction.
• Claws: Claws can be utilized to engage with rough surfaces and re-orient the direction of forces applied by the animal. This permits squirrels to climb tree trunks that are so big that they appear flat to such a little animal. 
• Claws, on the other hand, can obstruct an animal’s ability to hold extremely small twigs because they can wrap too far around and injure the animal’s paw.
• Adhesion: Adhesion works best on smooth surfaces and is an alternative to claws. Wet adhesion is frequent in tree frogs and arboreal salamanders and works via suction or capillary adherence. 
• Dry adhesion is best shown by geckos’ unique toes, which employ van der Waals forces to stick to a variety of materials, including glass.
• Gripping: Primates employ frictional grasping, which relies on hairless fingers. 
• The frictional force generated by squeezing the branch between the animal’s fingertips keeps the animal’s hand on the branch. 
• Other animals that employ gripping for climbing beyond primates include the chameleon, which has mitten-like grasping feet, and numerous birds that hold branches while perching or moving about.
• Reversible feet: Certain arboreal species, such as squirrels, have evolved extremely flexible ankle joints that allow the foot to rotate into a reverse position to regulate descent, particularly down large-diameter branches. 
• This enables the claws to hook onto the rough surface of the bark, defying gravity.
• Low mass center: Several arboreal species lower their center of mass during ascending to prevent pitching and toppling action. This can be done by changes in posture, altered body proportions, or reduced size.
• Small size: Arboreal creatures benefit from their small size in a variety of ways, including increased relative branch size to the animal, a lower center of gravity, better stability, reduced mass (enabling mobility on smaller branches), and the capacity to navigate through the more congested habitat. 
• Gliding animals are affected by size about weight, such as the lower weight per snout-vent length for ‘flying’ frogs.
• Hanging from perches: Several monkey, bat, and sloth species achieve passive stability by hanging beneath branches. Pitching and tipping become unimportant since the only way to fail is to lose their grasp.

SPECIALIZATION IN BEHAVIOR

• Arboreal animals have unique behaviors for moving in their environments, most notably posture and gait. 
• Arboreal animals, in particular, take longer steps, extend their limbs forward and back during a stride, assume a more ‘crouched’ stance to lower their center of gravity, and walk in a diagonal sequence.
• Environmental ramifications: Depending on their ability, arboreal mobility allows animals to acquire a variety of resources. 
• More sizeable species may be confined to branches with larger diameters that can support their weight, while smaller species may escape competition by going into narrower branches.
• Climbing without the use of trees: Several animals climb in various environments, such as rock heaps or mountains, and many of the same concepts apply because of inclines, narrow ledges, and balancing concerns. 
• Yet, there needs to be more research on the unique requirements of movement in these settings.
• Brachiation: Brachiation is a type of arboreal movement employed by monkeys to move quickly while hanging underneath trees. It is the pinnacle of arboreal mobility, including swinging the arms from one handhold to another. 
• A few species are brachiators and are all primates; it is a primary mode of movement for spider monkeys and gibbons, and female orangutans use it infrequently.
• Parachuting and gliding: Several species, like the flying squirrel, have developed gliding membranes, such as patagia, to cross gaps between trees. Certain animals, such as Rhacophorus (a “flying frog” species), have developed toe membranes that allow them to descend more slowly after leaping from trees and may delay their descent in the air by employing a technique known as parachuting.
• Climbing with no limbs: Several snake species are primarily arboreal, and some have evolved specialized musculature for this environment. 
• Snakes travel slowly over bare branches in arboreal settings utilizing a particular kind of concertina locomotion, but when secondary branches grow from the branch being moved on, snakes adopt lateral undulation and move considerably quicker. 
• As a result, snakes tend to perform better on small perches in cluttered settings, whereas limbed creatures appear to do better on big perches in clean environments.

ADAPTATION AT ENTRY LEVEL

• Arboreal animals are those that live in trees and have incredible adaptations to make the most of their lush environment at every level.
• There are just too many arboreal species to name individually. This list contains primarily or primarily arboreal species and higher taxa.
• Examples of Primates, Cats, Brushtail Possums, Opossums, Sloths, Anteaters, and Tree shrews.
• Emergent talent: Trees grow their highest in the forest’s apex, and residents must contend with strong winds, heavy rain, and sun exposure. To thrive here, species must be hardy and nimble. Therefore birds of prey dominate the roost. 
• The harpy eagle is found in rainforests from Mexico to Argentina and is named after the wind demons of epic Greek mythology. 
• It’s one of the world’s largest eagle species, one of the most formidable predatory birds, and the rainforest’s largest raptor.
• Canopy characters: The canopy is the forest’s next highest stratum, where the crowns of numerous trees meet to give shelter from the harshest weather. 
• This is a sort of Goldilocks Zone for arboreal creatures, where a diverse range of species may find protection from ground and sky predators. 
• Kinkajous are nocturnal and feed on ripe fruit. They are more closely linked to raccoons than any other canopy dweller. 
• They can effortlessly traverse through the trees and eat at the ends of branches because of their nimble fingers, flexible spines, and ankle joints that swivel 180 degrees. It’s not uncommon to observe them feeding upside down, dangling by their prehensile tail from a branch. 
• Understorey underdogs: The understorey is darker and more humid since it is shaded by the canopy, making it a suitable habitat for many amphibians that thrive in damp environments. 
• The red-eyed tree frogs of Central America are among the most distinctive residents of this forest layer, with orange toes, striped sides, and a rainbow of colorful leg colors that range from electric blue to orange to purple-red mixes. Its green backs blend perfectly with the foliage while hunkered down, yet when disturbed, a burst of color can dazzle predators or impress females looking for a mate.
• These frogs deposit their eggs on foliage that overhangs woodland ponds and puddles; after the eggs hatch, the tadpoles fall into the water to mature. Adult frogs travel through the trees until they reach a comfortable layer, occasionally reaching the canopy in pursuit of flying insects to feed.
• Researchers believe that since tree frogs may travel around inside the jungle to locate a sweet spot, they are safe from short-term climate change. But, continuing warmth and dryness will push them closer to the ground, potentially killing them.
• Bottom feeders:  It’s possible that you don’t identify trees living on the forest floor. Yet, this viewpoint ignores the plethora of insect species that thrive on decomposition in the forest’s lowest depths. 
• Termites are one of the rainforest’s top cleanup workers. 
• They can dwell underground, above ground, within dead wood, or in basketball-sized arboreal nests.

HABITAT

• Arboreal animals are animals that primarily live in trees and forest canopies. They have adapted to this unique environment and have various features that help them navigate and survive in the tree canopy.

The environment of arboreal animals includes:

• Tree branches and trunks provide a platform for arboreal animals to move and live on.
• Leaves and foliage: These provide shelter and camouflage for arboreal animals.
• Canopy: The forest canopy is the top layer of the forest, where most arboreal animals live. It provides a high vantage point for feeding and protection from predators on the ground.
• Weather: Arboreal animals are exposed to various weather conditions, including high winds, heavy rain, and extreme temperatures.
• Food sources: Arboreal animals can access various food sources, including leaves, fruits, nuts, insects, and other small animals in the trees.

FOOD CHAIN

• Primary producers: Trees, plants, and other vegetation are the primary producers in an arboreal ecosystem. They convert sunlight into energy through photosynthesis, which is the base of the food chain.
• Herbivorous arboreal animals, such as certain species of monkeys, sloths, and koalas, feed on the leaves, fruits, and other plant parts in the trees.
• Secondary consumers: Carnivorous or omnivorous arboreal animals, such as snakes, birds of prey, and some species of primates, feed on herbivorous animals, which are the primary consumers.
• Tertiary consumers: Apex predators, such as large cats or birds of prey, feed on the secondary consumers, carnivorous or omnivorous arboreal animals.
• Decomposers: Decomposers, such as fungi and bacteria, break down the remains of dead animals and plants, returning nutrients to the soil for use by the primary producers.
