Cockroaches have flat, oval-shaped bodies. The bodies of cockroaches are oily to the touch and may be cool or warm, depending on the temperature of their environment. The head of a cockroach is small and is covered by a shield-like pronotum.
World Trade Organization. Today, member countries number 125 (nearly the whole world except China, some former communist countries, and a number of small nations) and WTO rules apply to over 90 percent of international trade.
About two thirds of the WTO s around 150 members are developing countries. They play an increasingly important and active role in the WTO because of their numbers, because they are becoming more important in the global economy, and because they increasingly look to trade as a vital tool in their development efforts.
