Creation of see-through frogs

We have created the first see-through four-legged creature by artificial crossing between two recessive color mutants of the Japanese brown frog, Rana japonica, whose back is brown, although some small fish are also see-through (Fig. 18, Fig. 19, Fig. 20, Fig. 21).

We can observe organs of the same frog over its entire life without dissecting it, so it is useful as a new experimental animal.

We can see through the skin how organs grow, how cancer starts and develops, how toxins affect bones, livers and other organs.
