Freaky Transparent Frog

The Glass Frog or Crystal Frog (Hyalinobatrachium Pellucidum) is called such because you can see through its transparent flesh (including its guts). This frog is endangered, so this finding is heartening for environmentalists.

From Wikipedia:
Hyalinobatrachium pellucidum, also known as the glass frog or see-through frog is a species of frog in the Centrolenidae family. The frog is named for its skin which is translucent to the point that internal organs and surfaces immediately behind the frog can be seen. It is endemic to Ecuador. Its natural habitats are subtropical or tropical moist mountains and rivers. It is threatened mostly by habitat loss, although conservation programs have begun to help save this interesting creature. This frog is about the size of a fingernail.

It uses its claws to catch its prey, which is never bigger than the arachnid itself.

Freaky Foot-Binding Tradition

The origin of a foot-binding tradition called lily feet is uncertain. But it is believed that it appeared during the Five Dynasties (907–960).
According to legend, a king asked a lady-in-waiting named Ruiniang to bind her feet and dance on a golden lotus flower, so it was called three-cun lily feet. After that, the custom of foot-binding emerged. But this custom ceased after the founding of New China, and shoes for lily feet entered the museums.
