Wildlife of Brazil
The toco toucan is an animal typical of the Brazilian savannas.
Many varieties of poison dart frogs such as this yellow-banded poison dart frog can be found in the
jungles of Brazil.
The wildlife of Brazil comprises all naturally occurring animals, plants,
and fungi in the South American country. Home to 60% of the Amazon Rainforest,
which accounts for approximately one-tenth of all species in the world,[1] Brazil is
considered to have the greatest biodiversity of any country on the planet. It has the
most known species of plants (55,000), freshwater fish (3,000),
and mammals (over 689). It also ranks third on the list of countries with the
most bird species (1,832) and second with the most reptile species (744). The
number of fungal species is unknown but is large. Approximately two-thirds of
all species worldwide are found in tropical areas, often coinciding with developing
countries such as Brazil. Brazil is second only to Indonesia as the country with the
most endemic species.
Biodiversity
In the animal kingdom, there is general consensus that Brazil has the highest
number of both terrestrial vertebrates and invertebrates of any country in the world.
This high diversity of fauna can be explained in part by the sheer size of Brazil and
the great variation in ecosystems such as Amazon Rainforest, Atlantic
Forest and Cerrado. The numbers published about Brazil's fauna diversity vary
from source to source, as taxonomists sometimes disagree about species
classifications, and information can be incomplete or out-of-date. Also, new
species continue to be discovered and some species go extinct in the wild. Brazil
has the highest diversity of primates (131 species) and freshwater fish (over 3000
species) of any country in the world. It also claims the highest number
of mammals with 775 species, the second highest number of amphibians with 517
species and butterflies with 3,150 species, the third highest number of birds with
1,622 species, and fifth number of reptiles with 468 species. There is a high
number of endangered species, many of which live in threatened habitats such as
the Atlantic Forest or the Amazon Rainforest.
Scientists have described between 96,660 and 128,843 invertebrate species in
Brazil. According to a 2005 estimate by Thomas M. Lewinsohn and Paulo I. Prado,
Brazil is home to around 9.5% of all the species and 13.1% of biota found in the
world; these figures are likely to be underestimates according to the authors.
Enough is known about Brazilian fungi to say with confidence that the number of
native species must be very high and very diverse: in work almost entirely limited
to the state of Pernambuco, during the 1950s, 1960s and early 1970s, more than
3300 species were observed by a single group of mycologists. Given that current
best estimates suggest only about 7% of the world's true diversity of fungal species
has so far been discovered, with most of the known species having been described
from temperate regions, the number of fungal species occurring in Brazil is likely to
be far higher.
Because it encompasses many species-rich ecosystems for animals, fungi and
plants, Brazil houses many thousands of species, with many (if not most) of them
still undiscovered. Due to the relatively explosive economic and demographic rise
of the country in the last century, Brazil's ability to protect its environmental
habitats has increasingly come under threat. Extensive logging in the nation's
forests, particularly the Amazon, both official and unofficial, destroys areas the size
of a small country each year, and potentially a diverse variety of plants and
animals. However, as various species possess special characteristics, or are built
in an interesting way, some of their capabilities are being copied for use in
technology (see bionics), and the profit potential may result in a retardation of
deforestation.
Ecoregions
Brazil's immense area is subdivided into different ecoregions in several kinds
of biomes. Because of the wide variety of habitats in Brazil, from the jungles of
the Amazon Rainforest and the Atlantic Forest (which includes Atlantic Coast
restingas), to the tropical savanna of the Cerrado, to the xeric shrubland of
the Caatinga, to the world's largest wetland area, the Pantanal, there exists a wide
variety of wildlife as well.
Animals
Terrestrial mammals and reptiles
A jaguar
The wild canids found in Brazil are the maned wolf, bush dog, hoary fox, short-
eared dog, crab-eating fox and pampas fox. The felines found in Brazil are
the jaguar, the puma, the margay, the ocelot, the oncilla, and the jaguarundi. Other
notable animals include the giant anteater, several varieties
of sloths and armadillos, coati, giant river otter, tapir, peccaries, marsh
deer, Pampas deer, and capybara (the world's largest existing rodent). There are
around 131 (in 2022) primate species, including the howler monkey, the capuchin
monkey, and the squirrel monkey, the marmoset, and the tamarin.[2][10]
Brazil is home to the anaconda, frequently described, controversially, as the largest
snake on the planet. This water boa has been measured up to 30 feet (9.1 m) long,
but historical reports note that native peoples and early European explorers claim
anacondas from 50 to 100 feet (30 m) long.
Invertebrates
There are 1107 known species of non-marine molluscs living in the wild in Brazil.
The second largest spider in the world, the Goliath birdeater (Theraphosa blondi),
can be found in some regions of Brazil.
Insects
It is calculated that Brazil has more insects than any country in the world. It is
estimated as having over 70,000 species of insects, with some estimates ranging
up to 15 million, with more being discovered almost daily. One 1996 report
estimated between 50,000 and 60,000 species of insects and spiders in a
single hectare of rainforest. About 520 thysanoptera species belonging to
six families in 139 genera are found in Brazil.
A common rhea
Birds
Brazil ranks third on the list of countries, behind Colombia and Peru, with the most
number of distinct bird species, having 1622 identified species, including over 70
species of parrots alone. It has 191 endemic birds.[5] The variety of types of birds is
vast as well, and include birds ranging from brightly colored parrots, toucans,
and trogons to flamingos, ducks, vultures, hawks, eagles, owls, swans,
and hummingbirds. There are also species of penguins that have been found in
Brazil.
The largest bird found in Brazil is the rhea, a flightless ratite bird, similar to
the emu.
Aquatic and amphibian

Brazil has over 3,000 identified species of freshwater fish and over 500 species
of amphibians.[5] As elsewhere in South America, the majority of the freshwater fish
species are characiforms (tetras and allies) and siluriforms (catfish), but there are
also many species from other groups such as the cyprinodontiforms and cichlids.
While the majority of Brazil's fish species are native to the Amazon, the Paraná–
Paraguay and the São Francisco river basins, the country also has an unusually
high number of troglobitic fish, with 25 species (15% of the total in the world)
known so far. The most well-known fish in Brazil is the piranha.
Other aquatic and amphibian animals found in Brazil include the pink dolphin (the
world's largest river dolphin), the caimans (such as the black caiman), and
the pirarucu (one of the world's largest river fish). Also familiar are the brightly
colored poison dart frogs.
Fungi
The diversity of Brazil's fungi - even the small amount known so far to scientists - is
astonishing. Using only conventional microscopy, and examining living leaves
collected from various plants, the mycologist Batista and his colleagues, working in
Pernambuco in the 1950s, 1960s and 1970s, regularly recorded more than one
fungal species, and sometimes up to ten on a single leaf. Although information
about fungi worldwide remains very fragmented, a preliminary estimate, based only
on the work of Batista, shows that the number of potentially endemic fungal
species in Brazil already exceeds 2000. Also, fungi is very often spotted in Brazil.
Plants
Princess flower
Brazil has 55,000 recorded plant species, the highest number of any
country. About 30% of these species are endemic to Brazil. The Atlantic
Forest region is home to tropical and subtropical moist forests, tropical dry
forests, tropical savannas, and mangrove forests. The Pantanal region is
a wetland, and home to a known 3,500 species of plants. The Cerrado is
biologically the most diverse savanna in the world.
The pau-brasil tree (also known as brazilwood and the origin of the country's
name) was a common plant found along the Atlantic coast of Brazil. But excessive
logging of the prized timber and red dye from the bark pushed the pau-brasil
towards extinction. However, since the inception of synthetic dyes, the pau-brasil
has been harvested less.
All over Brazil, in all biomes, are hundreds of species of orchids, including those in
the genera Cattleya, Oncidium, and Laelia.
Cattleya aclandiae or Lady Ackland's cattleya
Along the border with Venezuela lies Monte Roraima, home to many carnivorous
plants. The plants evolved to digest insects due to the oligotrophic (low level of
nutrients) soil of the tepui.
Threats to wildlife
"At bottom right and bottom center, deforestation and cultivation are evident by the regular, rectangular
shapes that delineate plots."
More than one-fifth of the Amazon Rainforest in Brazil has been completely
destroyed, and more than 70 mammals are endangered. The threat of extinction
comes from several sources, including deforestation and poaching. Extinction is
even more problematic in the Atlantic Forest, where nearly 93% of the forest has
been cleared. Of the 202 endangered animals in Brazil, 171 are in the Atlantic
Forest. Currently, 15.8 million acres of tropical ecosystem have been completely
eliminated to farm sugarcane for ethanol production. And additional 4.5 million
acres is planned to be planted during the next four years. 70-85% of Brazil's
transportation energy is derived from ethanol, or various mixtures of ethanol and
petroleum-based fuels. Only about 15-20% comes from imported petroleum. This
massive national biofuel program has been devastating to tropical wildlife diversity,
and to the global climate/environment. With its acquisition of
BioEnergia, BP (British Petroleum) is planning to further expand Brazil's ethanol
program.
