Paraíba do Sul River in the context of Black tetra

👉 Paraíba do Sul River in the context of Black tetra

The black tetra (Gymnocorymbus ternetzi), also known as the petticoat tetra, high-fin black skirt tetra, black skirt tetra, black widow tetra and blackamoor, is a species of freshwater ray-finned fish belonging to the family Acestrorhamphidae, the American characins.

It is native to the Paraguay River basin of south-central Brazil (mainly Pantanal region), Paraguay and northeast Argentina, but there are also populations in the upper Paraná and Paraíba do Sul Rivers that likely were introduced. It was formerly reported from the Guapore River, but this population is part of G. flaviolimai, which is found throughout the Madeira River basin and was described in 2015. The black tetra is often kept in aquariums.

Paraíba do Sul River in the context of Mantiqueira Mountains

The Mantiqueira Mountains (Portuguese: Serra da Mantiqueira [literally: Mantiqueira Mountains Chain]) are a mountain range in Southeastern Brazil, with parts in the states of São Paulo, Minas Gerais and Rio de Janeiro.

The name shows the range's great importance as a source of drinking water, and the waters supply a great number of important cities in the southeast of Brazil. From its brooks are formed the Jaguari River, which supplies the northern region of Greater São Paulo; most left-bank tributaries of the Paraíba do Sul River, which crosses a densely populated and highly industrialized region; and the Grande River, which is the source of the Paraná River, one of the longest and most important in South America and the river with the world's largest hydroelectric output, through a series of power plants way down the river to Argentina and Paraguay.
