The Transformation of Lençóis Maranhenses

Lençóis Maranhenses National Park stands among the most fascinating destinations on Earth, masterfully balancing sophistication with the raw power of nature. 

Although its landscape resembles a desert, the region is bathed in intense rainfall during specific periods. The annual rainfall in Maranhão can vary between 700mm and 2200mm.

These precipitations are responsible for filling the valleys between the dunes. The lagoons originate from a layer of impermeable rock beneath the sand, which retains rainwater on the surface. Thus, a turquoise mosaic is etched across the Maranhão landscape.

After all, are there fish in the lagoons of Lençóis Maranhenses?

The answer is yes, there are fish in the lagoons of Lençóis Maranhenses!

Although the lagoons form during the rainy seasons, aquatic life has developed admirable strategies to persist in this natural sanctuary during times of drought. 

The wolf-fish — widely known as traíra — is an example of extraordinary adaptation. During the dry months, this species seeks refuge in the residual mud after the waters evaporate. Beneath the soil, these fish remain in a state of dormancy until the rains return to the region. In addition to the adaptation of species like the wolf-fish, fauna also re-establishes itself through natural channels. The meeting of the lagoons with the restinga coastal vegetation creates a memorable setting, where every swim represents a profound immersion into the strength of nature.
