Villager Edson de Souza from the Rumao Island community pulls into his canoe an arapaima or pirarucu, the largest freshwater fish species in South America and one of the largest in the world, while fishing in a branch of the Solimoes river, one of the main tributaries of the Amazon, in the Mamiraua nature reserve near Fonte Boa about 600 km (373 miles) west of Manaus, November 24, 2013. Catching the arapaima, a fish that is sought after for its meat and is considered by biologists to be a living fossil, is only allowed once a year by Brazil's environmental protection agency. The minimum size allowed for a fisherman to keep an arapaima is 1.5 meters (4.9 feet). [Photo/Agencies]
