Flat, long hind limbs, large sucker, developed webbed between fingers and toes. Mesenchymal cartilage (branch sign) exists between the two finger joints at the end, which is suitable for arboreal life. There are many kinds, distributed in subtropical and tropical humid areas in eastern and southeastern Asia. There are 29 species in China. The spotted-legged tree frog is the most widely distributed, ranging from southern Gansu to southern Tibet in the north.
Living habits
Many kinds of tree frogs inhabit the humid broad-leaved forest area and its marginal zone.

The back is mostly green or changes with the environment. Breeding habits reflect the arboreal lifestyle, and most species lay eggs on branches and leaves that extend above the pond. For example, the tree frog in Emei, in the evening after the rain in April-May, the males and females embrace each other and climb the tree, choosing branches and leaves perpendicular to the pool to lay eggs. When the female lays eggs, the liquid is discharged first, and the left and right tarsal joints are stirred with each other to form foam, and the eggs are laid in the foam; The male secretes semen to fertilize the egg. Repeat this for 2 ~ 3 hours. After laying eggs, the male leaves immediately, and the female leaves after wrapping the hair follicle with leaves in her hind limbs. Follicles are milky white. Foam liquefaction before and after culture. Tadpoles reach the pool under the tree through movement or being washed by rain, where they continue to grow and develop and complete transformation.
Tree frog with spotted legs lives in the grass beside ponds or rice fields, and its follicles are produced in the grass or float on the water. Hainan tree frog lives near a stream, and its eggs are laid in puddles by the stream, without follicles. This species is the only tree frog in China that does not produce follicles. The small drum tree frog in Sri Lanka lays about 20 eggs on the land without follicles. Female frogs have the habit of protecting eggs and develop directly into young frogs.
The black webbed tree frog is arboreal, extremely flat, with thin crotch, developed webbed fingers and toes, and skin folds on the outside of anus and front and rear limbs, which increases the body surface area. When gliding from high to low, the fins are open, which can slow down the landing speed. The black-brown tree frog can glide parabolically to the ground from the height of 4 ~ 5 meters, so it is called flying frog.
