In a biological context, arboreal is a term used to associate with trees, any mammal/animal which lives on trees are arboreal.

• Examples of arboreal animals are squirrels, koalas, primates, sloths, spider monkeys, leopards, chameleons, geckos, bats, tree frogs, snakes, birds, lizards, and tree snails.
• Many animals have sharp claws which help them to hut their prey. Their claws also help to climb up the trees, where they live. Tiger is one such example.

Some other keywords are:

• Terrestrial refers to things related to land or the planet Earth. Terrestrial may also refer to Terrestrial animal, an animal that lives on land as opposed to living in water, or sometimes an animal that lives on or near the ground, as opposed to arboreal life (in trees).
• An amphibian is a vertebrate (an animal with a backbone). Amphibians are cold-blooded, which means that their body temperature changes with their surroundings. They spend part of their lives in water (breathing with gills) and part of their lives on land (breathing with lungs).
• Aquatic means relating to water, living in or near water, or taking place in water, does not include groundwater, as "aquatic" implies an environment where plants and animals live. Aquatic may also refer to Aquatic animals.

So, we may say that arboreal animals, sharp claws, trees are interlinked and correctly matched.
