The Orinoco, which runs through Venezuela and Colombia, is one of the longest rivers in South America. Its habitats include the cool clearwater of the mountain headwaters, the turbid whitewater of the main river, and the warm brackish waters of the delta where the river empties into the Caribbean Sea. In the Orinoco Basin there are also blackwater creeks, oxbow lakes, and seasonal floodplains (warm, tea-colored, soft, acidic). The focus of this blog will be on these latter blackwater habitats, found in large part on Los Llanos - the savanna plains of the Lower Orinoco.
