Mapa Arapaima

Arapaima mapae is a species of freshwater fish endemic to Brazil, where it is known only from Lago do Amapá in Amapá State.

It is a member of the arapaimas, a genus of air-breathing fish that contains some of the world's largest freshwater fish. It is known only from a single holotype collected in 1837, which was purchased by a French army officer from an indigenous trader in French Guiana, and later described as a new species by Achille Valenciennes. A 2013 review of wild-caught Arapaima specimens worldwide found sufficient morphological evidence to classify it as a distinct species.
