The word ''arboreal'' refers to which normal location of a frog?

''Arboreal'' locomotion is the locomotion of animals in trees. A tree frog in any species spends a major portion of its lifespan in habitats in which trees are present. This is known as ''arboreal'' state. These frogs do not normally descend to the ground and rarely leave the trees. They build foam nests on leaves after spawning by releasing the eggs and sperms. The foam nests are created using bubbles blown with an oral secretion.

Examples: gladiator and red-eyed tree frogs of Costa Rica; gray tree frog of eastern North America; big-eyed tree frog of Tanzania; Malabar tree frog of India. These frogs are usually tiny as their weight has to be carried by the branches and twigs. They are typically smaller and more slender than terrestrial frogs. They have well-shaped discs at the fingers and toes tips as well as the limbs, resulting in a superior grasping ability. The genus ''Chiromantis'' of the ''Rhacophoridae'' (foam-nest tree frog) is most extreme in this respect.

Tree frogs members are ''Hylidae'' or ''true'' tree frogs occur in temperate to tropical parts of Himalayas, Australia and Americas. Boophis is a genus of highly ''arboreal'' frogs of Madagascar.
