The country is regarded as one of the 17 countries Megadiverse by having a large number and diversity of species, especially in regard to plant species and birds. And the climatic diversity and at the same time, the stability of the elements of climate, have made many plant and animal species from other parts of the world have been introduced and have found a very suitable habitat for development and nearly all crops domesticated species can be cultivated by man in Venezuela on very favorable terms, a fact already recognized the nearly two centuries ago by Andres Bello Silva in the agriculture of the torrid zone. Venezuela is composed of three strands hidrograficas the Caribbean Sea, the Atlantic Ocean and the Lake of Valencia, which is an endorheic basin. The main one is the Caribbean by the number of rivers that form, although usually short-course and flow of small and irregular, with some exceptions such as Catatumbo, born in Colombia and drains into the Lake of Maracaibo. Andalusia Oceano Atlantico drain the extensive Orinoco River basin, whose surface is greater than the whole of Venezuela. The Orinoco basin is the third in South America for its surface and gives rise to a flow of around 33,000 m per second, making one of the Orinoco rivers flowing into the world and also one of the most valuable in terms of renewable natural resources. A river is a unique event in the world is the Casiquiare, which is a derivation of the Orinoco and natural that, after about 500 km long, flows into the Black River tributary which is in turn the Amazon.
The main tributaries are the Venezuelan Orinoco and Apure Arauca by the left and Ventuari, the Caroni and Caura by the right, among others.
