MONGLA, MONG LA, SHAN STATE, MYANMAR - 2003/01/01: Rare animal parts, monkey skulls, bear gall bladders and tiger's penis are sold in the wildlife markets of Mongla, a remote town on the border with China. Much of the wildlife is eaten as it is believed to be an aphrodisiac. The illegal trade in endangered species is believed to be worth more than US$5 billion worldwide every year.
