The singular multi-finger 蟾 (scientific name: Pseudis paradoxa) is a frog family, and the genus is a amphibious animal. Mature individuals are 45-65 mm in length, short and bloated, short and blunt. The eyes are big and the iris is golden yellow. The tympanic cavity is visible and is pinched at the skin folds of the jaw. It means that it can move freely, the toes are completely filled with sputum, and there are no suction cups on the limbs. The back is green with black spots. The abdomen and limbs are brown with white spots. Females in both sputum and adulthood are larger than males.
This species is the most common difference between cockroaches and adults. The size of the dragonfly is 3-4 times that of the adult frog, and the length is generally 22-25 cm.
Inhabited in ponds, lakes, lagoons and cisterns next to the creek, mainly waters with stagnant water and abundant vegetation, surrounded by forests, grasslands or savannas.
The breeding season seems to be related to sudden rainfall and temperature changes. The female will lay eggs next to the aquatic plants and hatch out. The eggs are green and foamy, and the hatched clams are also green, but will fade away in a few days.
