The Arapaima Leptosoma constitutes a recently discovered type of freshwater fish. To date, we know of only one individual of this new species. Awareness of their existence occurred so recently that no common name exists as of yet. The search for more of their kind remains ongoing.
This creature also represents the first newly recognized species of Arapaima since 1847. Researchers discovered the Arapaima Leptosoma in the Purus river, in the Amazon Basin, in South America. Its discovery happened quite by accident.
No data concerning their numbers exist yet. The IUCN considers them to be a threatened species, however, this classification occurs due to the fact that all fish species endemic to the region appear to be threatened by overfishing.
Arapaima Leptosoma Physical Characteristics
Experts so far know of only one specimen, therefore only general information concerning the Arapaima Leptosoma remains known. All species of Leptosoma appear to be among the largest known species of freshwater fish.
Like all other members of its family, they evolved as an air-breathing fish. The individual discovered seems to be an adult, and therefore representational of its species.
It measured about 10 ft (3 m) in length. Unlike most species of Arapaima, the Arapaima Leptosoma stays thin and elongated in shape.
In color, they present a combination of grayish-silver and red.
