Tiger Frog

Female tiger frogs are larger than males, with adult tiger frogs reaching up to 12cm in length, and ideally should weigh between 250 and 500 grams. The skin is relatively rough, with dark irregular markings on the head and the side of the body. The back is yellowish green and slightly brown, with a dozen rows of longitudinally arranged skin ribs, and small warts scattered between the skin ribs.

The ventral surface of the tiger frog is white, also with irregular markings, and there are gray-brown spots on the pharynx and thorax. There are transverse spots on the fore and hind limbs. The name is given to these spots because they look slightly like tiger skin. The toes are pointed and rounded with full webbing between them. The forelimbs are stout, and the finger pads are developed and gray. The male frog has a pair of external vocal sacs. It has been listed as a national key animal for protection.

Head Characteristics

The head of the tiger frog is generally triangular, and there is no obvious boundary between the head and the trunk. The end of the head is pointed, which reduces drag when swimming and facilitates rapid swimming. The mouth is very wide, except for feeding, generally rarely open. The eyes are located on the dorsal side of the head or on both sides of the head. Above and below.

Both have eyelids, to which are attached transparent transient membranes folded inward, which move up to cover the eyes during diving. The external nostrils have a nasal valve that can be opened and closed at any time, thereby controlling the flow of gas in and out. Males have a pair of light blue sac-like projections on the ventral surface of the head on the lateral part of the pharynx, called the vocal sacs, is a **** sounders, can expand the larynx to emit such as barking like a loud bark, play a role in attracting females.

Limb characteristics

The carapace has two pairs of limbs. The forelimbs are slightly shorter, each with 4 toes, and play a major role in supporting the front of the body, as well as assisting in predation and body balance for swimming. The hind limbs are longer, each with 5 toes, webbed between the toes, mainly in the water swimming and jumping on land to play a propulsive role. The whole body is golden yellow with black spots.
