What types of mammals can I see?
The Amazon is
home to a great variety of mammalian life. Although many species
are reclusive or nocturnal, most eventually cross, bathe, drink or visit
the rivers for one reason or another. Some make the rivers their
homes. Fishermen are very often treated to sightings because they
spend their day at the interface of river and jungle. Commonly sighted
Amazon mammalian life includes the species listed below.
The Oddballs - Among the most unique of Amazonian
animals are the tapir (anta) and the capybara. The
Brazilian tapir (Tapirus terrestris), a relative of the rhinoceros,
is a large ungulate inhabiting jungle watercourses throughout Amazonia.
Feeding on fruits and leaves, this big, strange, almost hairless creature
can sometimes be seen walking along banks or swimming across rivers.
Even more aquatic, and often sighted in similar habitats, the capybara is the world's largest rodent, often exceeding
4 feet in length and 120 pounds. The paca (Agouti paca), a
smaller cousin to the capybara (Hydrochaeris hydrochaeris), feeds
on vegetation along riverbanks at night while the agouti (cutia/Dasyprocta
sp.) is more often encountered on jungle trails. All of
theses species have learned to be very wary of man because of their popularity
as menu items for the local population.
The Cats - The most thrilling and probably
rarest sighting in the Amazon is the jaguar (Felis Onca).
Largely nocturnal and solitary, the great cat of the Amazon is now on the
list of endangered species. The onca's only predator, man,
has severely reduced the population of these magnificent animals in order
to make profits from their beautiful spotted pelts. Several other,
smaller species of cat are significantly more common and easily seen.
The ocelot (Felis pardalis) and the margay (Felis wiedeii),
both under 35 pounds, range throughout the Amazon. Although primarily
nocturnal, sightings of these cats often occur in areas of dense cover.
The puma (Puma concolor) and jaguarundi (Felis yagouroundi),
although not very common in Amazonia and not riverine in their habits,
are also sighted here.
Up in the Trees - If you turn your attention
up into the trees at the edges of the rivers, you can spot monkeys and
sloths. Over forty species of monkey are found in Amazonia.
Ranging from the good-sized howler monkey (up to 35 pounds) down to the
tiny marmosets and tamarins (weighed in ounces), New World monkeys share
one common characteristic, they all have tails. Look quickly, because
their acrobatic skills allow them to move rapidly through their arboreal
environment. Sloths (pregisa),
on the other hand, hardly move at all. The three-toed sloth, and
its larger two-toed cousin, may take days to move from one tree to the
next. Once you've spotted one, you can observe it at your leisure.
In the Water - The rivers are home
to two species of fresh water dolphin and a giant manatee. The large, pink boto (Inia geofrensis) is a most unusual looking dolphin with its long snout, external ears and
flexible neck. The smaller, gray tucuxi (Sotalia fluviatilis) looks more like our idea of Flipper, the TV star. Both species are
widespread, not hunted, and very commonly seen by anglers. Swimmers
are often treated to curious tucuxi circling and peeking at them when they
take a dip in the river. The Amazon manatee (Trichechus inunguis),
a giant reaching over 1000 pounds is now endangered because of hunting
for its meat, oil and hide. Giant otters or 'ariranha' (Pteronura
brasiliensis), as big as a man, inhabit the lagoons of Amazonia.
Although also on the endangered list, they are fairly commonly seen by
anglers. They forage in groups and won't hesitate to let you know
by splashing and barking, just how unhappy they are to have you invading
their territory. A smaller species of otter, locally called 'lontra'
(Lutra longicaudis) is very widespread and also often sighted .
On the Banks - Anglers can also see two species
of armadillo, including the Amazon giant, (tatu). Two species
of anteater are found in Amazonia. The giant anteater (Myrmecophaga
tridactyla) is totally terrestrial and its smaller cousin (Tamandua
tetradactyla) is mostly arboreal. Closely resembling small
feral pigs, peccaries (Tayasu tajasu) roam Amazonia in small herds
of twenty or so individuals. They can occassionally be seen rooting
at rivers edge or even swimming in the river. Three species of Amazon
deer or 'Viado' (Mazama sp./Odocoileus virgineanus), the racoon-like
coatimundi (Nasua nasua) , bush 'dogs' (Speothos venaticus)
and the 'Tayra,' (Eira barbara) a mink-like member
of the weasel family, also often treat the visitor with a sighting. |
