Mexican Chub (Evarra bustamantei)

The Mexican Chub is one of three known species in this genus, all of them are now extinct due to habitat loss.

***

This Mexican Chub was described in 1955, it inhabited canals and streams in the Valley of Mexico, a plateau in central Mexico that now is nearly completely overbuilt by Mexico City, one of the largest cities on the planet.

The species died out at around 1983 as a result of the complete drying of the water bodies in the valley due to the withdrawal of water by the agriculture and the unstoppable growth of the city and its suburbs.
