No.03 Japanese tree frog

Tree frogs are classified in the Amphipoda, Anura (Amphipoda: Anura), in the family Anura (Anura: Anura). They prefer waterside areas because they lay their eggs in rice paddies and ponds, and can be seen on a daily basis in Japan.
When they catch their prey, they pounce on it with their sticky tongue slightly outstretched. The prey is then swallowed whole.
Their skin is covered with a smooth mucous membrane, which contains toxic substances to protect their bodies from bacteria.
Although they are safe to touch by hand, touching them with a wounded hand or rubbing the eyes or mouth with a hand that has touched them can cause tingling or irritation.
It is necessary to wash hands well after touching frogs.

CT images showed that the frog had no bones corresponding to ribs.
Therefore, there are no dense areas from the chest to the abdomen, and one can imagine that the area under the skin is filled with internal organs as it is.
The tail is so short and degenerated that it is hard to imagine the original form of a tadpole, and instead we see long, three-jointed hind legs. The frog swallows its prey whole, but it seems to have teeth in its upper jaw, and the 3D model shows that they are lined with fine protrusions.
The 3D model shows that the frogs have a series of fine protrusions in their upper jaw, which may be used to prevent their prey from escaping from their mouth.
