The fauna of the Pantanal is one of the richest on the planet, both in variety and quantity, and the dense vegetation of the Pantanal ends up benefiting the human visitor even more in facilitating the visualization of all this wild life.
Pantanal’s extraordinary biodiversity includes around 660 species of birds, 100 species of mammals, 160 species of reptiles, 40 species of amphibians, more than 260 species of fish and incalculable numbers of insect species, of which more than 1,000 are known different butterflies.
The Pantanal is one of the last refuges for a large number of mammals that were once found in abundance scattered throughout South America, such as the Spotted Puma, the Puma Parda, the Jaguatirica, the Lobo Guará, the Anta, the Tamandua, the Ariranha, Capivara, Cervo and many others.
However, as rich as the Pantanal is in terms of mammals, when we speak of birds we enter into other dimensions. For ornithologists, the Pantanal reveals a true paradise where large numbers of birds of the most varied species mark their constant presence. From the first rays of light on the horizon the Pantanal is filled with songs of birds, the most harmonious and refined of some to the hoarse cries of others. All sizes of birds are abundantly represented in the Pantanal, from the tiny Hummingbird to the giant and majestic Tuiuiu, the bird symbol of the Pantanal.
With more than 200 species represented, also reptiles and amphibians ensure constant encounters with visitors to the Pantanal. Especially the Gators characterize the Pantanal landscapes, both in the water and outside. The mythical Anaconda, although less abundant than the Aligator, is often found on the banks of the rivers and coriches and the most attentive among us may discover the beautiful iguanas, camouflaged and mingling with the foliage of the trees.
The fish are represented by more than 260 species, but what impresses more than that are the quantities of them. Thanks to flooding in the Pantanal, the waters are rich in nutrients and offer extremely favorable conditions for fish reproduction. It is not surprising that they form the food base for most of the Pantanal animals.
Another source of food for huge numbers of animals are insects, represented by an unimaginable variety of species and mostly unscientific or simply unknown. Although not as visible as birds, insects also manifest themselves, especially at night, with concerts of the highest quality and duets with frogs and toads. By day, more than a thousand species of butterflies assure their presence and at the end of the flood season it is not uncommon to find thousands of them at a glance.
Regardless of your reason for a visit, whether scientific, for some specific interest or for simple love of nature, the Pantanal is undoubtedly one of the most beautiful and privileged places on the planet for wildlife observation!
