this episode examines some of the
Amazon's most iconic inhabitants
the Colossal Anaconda the easy-going
sloth the cold-blooded Caiman the
hair-raising tarantula and the
Mysterious Amazon River dolphin
in a place filled with Legends none of
gripped the human imagination quite like
the Anaconda
with a strangle hold over the twisting
morass of swamps marshes and streams
that comprise the Amazonian Wetlands the
Anaconda family consists of five species
among them the largest snake in the
world
while the gargantuan proportions of a
green anaconda are subject to Wild
speculation what is certain is that all
anacondas are perfectly adapted to the
waterways of their rainforest home
relatively slow and cumbersome on the
land the Anaconda utilizes the murky
river system to travel effortlessly and
to hunt with ruthless efficiency
able to remain submerged for over 10
minutes they are expert Hunters of the
fish Turtles and Cayman that inhabit the
Abundant Waters of the Amazon
but that's not all
the entire jungle ecosystem is dependent
on its waterways and here the waterways
give the Anaconda license to rule
High set eyes and nostrils allow it to
remain almost entirely hidden in the
water while laying in wait for the
land-based prey
anacondas will eat anything they can
overpower
and for a snake this big few in the
Amazon are safe
foreign
like all reptiles anacondas are
ectothermic obtaining their body heat
from their environment the Amazon
rainforest year-round average
temperature of 27 degrees Celsius makes
this paradise for big snakes
beneath the thick jungle canopy of the
Amazon darkness comes quickly
but the Anaconda has adapted to hunt
without light
specialized sense organs around the lips
detect body heat the flickering Fork
tongue takes chemical cues from the air
and sensitive skin detects sounds and
vibrations on land and in water
foreign
[Music]
onto its prey with hundreds of
razor-sharp teeth it's not the
anaconda's bite that kills a
non-venomous snake the Anaconda employs
its long muscular body to coil around
its jungle prey and patiently suffocate
them
[Music]
meals are swallowed whole
disengaging the lower jaw the snake can
stretch its mouth around food far bigger
than its head with the menu as wide as
its gape the Anaconda preys on all that
the Amazon has to offer
a top-order predator of the Amazon the
greatest threat to the deadly Anaconda
is from man
prized for their legendary status as
well as their magnificent skin the
surprisingly shy and Elusive nature of
these snakes has so far kept them safe
allowing the legend to continue to grow
[Music]
[Music]
from the waters to the trees the Amazon
rainforest is a densely interwoven
ecosystem and one humble creature is the
true embodiment of this
[Music]
sloths are the most prevalent tree
dwelling mammals in South America they
are also the least conspicuous concealed
within the rainforest canopy sloths
display a distinctive preference for the
widely distributed sacropia tree also
known as the sloth tree
coexist as one with the jungle
to the point where their coat is a
jungle in microcosm
considered walking ecosystems sloths
bodies are covered in thick coats that
Harbor their own animal and plant life
with the Amazon's almost daily rainfall
and high humidity the sloth provides a
hairy habitat for moisture-seeking moths
beetles cockroaches and a specialized
form of algae
found nowhere else in the world this
host Pacific microorganism has evolved
with the sloth and is passed on to
infants as they cling to their mother's
fur
[Music]
while the algae AIDS in camouflage this
symbiotic relationship also extends to
the sloth's diet
as folivores the sloth's main food
source is leaves which are not only
tough to digest but provide little
energy
by growing and consuming their own algae
Gardens sloths are able to boost their
nutritionally poor diet
[Music]
their diets sloths carry around 20
percent less muscle tissue than most
mammals
lacking the ability to make a quick
getaway
sloths are at the mercy of Amazon's many
predators predators like the Jaguar
[Music]
an expert climber sloths can do little
to defend themselves from this feline
flow but little is exactly what they do
for great parts of the day sloths only
move when necessary hence the name sloth
often remaining in the same tree for
years when sloths do move they are quiet
gentle and slow minimizing disturbance
to the foliage and never calling
attention to themselves
in this way a lack of speed is
advantageous
the sloth's economy of movement leaving
Predators completely oblivious to their
presence
in their own effortless style sloths are
masters of the Amazon but their success
in the rainforest has come at a cost
with sloths unable to survive outside
their specific habitat
as the embodiment of the
interconnectivity of the Jungle to
preserve the Amazon is to preserve the
sloth
[Music]
the vast expanse of the Jungle its
rainforest and river systems its
mangroves and marshes has fostered a
diversity of life
and a diversity of Cayman
[Music]
members of the Ancient Order of
crocodilians Cayman are another apex
predator of the Amazon's waterways with
six species from the diminutive dwarf
Caiman to the mighty five meter long
black caiman all are found in the Amazon
once covering most of South America the
Amazon rainforest is over 55 million
years old
foreign
with this ancient environment the
cayman's lineage is even more
prehistoric
and they are considered among the most
perfectly adapted creatures on the
planet
propelling themselves through the water
with their thick powerful tails and
webbed feet Caiman are excellent
swimmers with dominion over the Amazons
rivers and lakes
hunting primarily by sight their large
eyes have vertical pupils allowing for
excellent night vision
an additional transparent eyelid grants
protection and clearer vision while
stalking beneath the surface of the
Amazon's waterways
snatching prey in their powerful toothy
Jaws they are opportunistic predators
taking advantage of whatever food source
is most abundant with a wide diet
including fish amphibians insects and
snails as well as other reptiles and
large mammals for cayman the Amazon is a
smorgasbord
foreign
but the Amazon also knows privation
during the annual dry season the waters
recede and ecosystems once connected by
floodplains and streams become cut off
reducing the cayman's hunting grounds
but Cayman are equipped to wait the dry
season out
able to go for months without food
[Music]
conserving energy they reduce their
hunting activity
being cold-blooded no energy is wasted
on producing heat instead drawing it
from the environment
when times get really tough Caymans can
resort to cannibalism
[Music]
climate change poses a more existential
threat the sex of crocodilians is
determined by temperature while
incubating in their eggs when held at
around 30 degrees Celsius hatchlings
tend to be female just four degrees
higher and the hatchlings are
predominantly male with global warming
scientists are concerned about the
possibility of an overpopulation of male
caiman
will this ancient species be able to
adapt to a rapidly changing world
Cayman have bounced back before
once hunted to near Extinction for their
valuable liver hide this led to an
imbalance in the Amazon ecosystem
strict anti-hunting laws and protected
habitats have made the Caiman a
conservation success story in the Amazon
and their return to the top of the food
chain has played an important role in
maintaining the balance of the Amazon's
fragile ecosystem
foreign
undergrowth a whole other world exists
with sunlight blocked out by the thick
rainforest canopy above this Shady humid
environment is littered with decomposing
plant and animal matter returning
nutrients to the Jungle ecosystem
but the rainforest floor is also home to
a surprising abundance of life
a staggering 90 percent of all the
creatures that live in the Amazon are
arthropods
a group of invertebrates with external
skeletons arthropods include insects
centipedes scorpions and spiders
[Music]
with an estimated
3600 species of spider in the Amazon one
species is arachnophobia personified
the tarantula
inhabiting the planet since the age of
the dinosaurs there are over 800 species
of tarantula spread over most of the
world
[Music]
tarantulas are the biggest of the
spiders and the biggest of the big are
found in the Amazon
here tarantulas can grow to the size of
dinner plates
occupying underground burrows or tree
Hollows unlike many spiders tarantulas
do not use their web to catch prey
preferring instead to Ambush them
laying in weight in their burrow
entrances tarantulas are coated in
sensitive hair that helps them detect
prey called seta These Fine sensory
organs are used to pick up on vibration
identify chemical signatures akin to
smell and possibly even detect sound
this coating of seta allows tarantulas
to determine the location and size of
approaching Quarry before they see it
look
the typical tarantula diet consists
mainly of insects frogs small lizards
and even mice
the enhanced proportions of Amazonian
tarantulas means that they are capable
of tackling larger preys
thank you
[Music]
when the victim is within range the
tarantula launches its attack using its
legs to grab hold of its Quarry and
paralyzing it with Venom once the victim
is dead tarantulas administer an
injection of digestive enzymes
liquefying their meals and sucking them
up through straw-like mouths
despite the tarantula's fearsome
appearance they pose little threat to
man
man on the other hand poses a threat to
tarantulas through habitat destruction
and the pet trade
fortunately in the case of the Amazon
all indications are that the tarantula
population is continuing to thrive
foreign
ing 40 of South America each year the
Waters of the Amazon River burst their
Banks transforming lowland jungles into
enormous flood Plains
[Music]
Amazon river dolphins also known as boto
dolphins are the largest freshwater
dolphin in the world and a mystery of
the animal kingdom
[Music]
while much remains Unknown about these
unique creatures they are the unlikely
Specialists of the Amazon River
[Music]
live their entire lives in the turbid
waters of the Amazon and its tributaries
leading to a set of very specific
adaptations the botos long broad
flippers and low dorsal fin granted
extreme maneuverability even in shallow
water
thank you
unfuse neck vertebrae allow river
dolphins to turn their heads 180 degrees
to either side a vital adaptation in
navigating a choked Maze of submerged
obstacles
sweeping their heads from side to side
the botos employ an advanced
echolocation system to navigate and to
locate prey with pinpoint accuracy with
small eyes there is uncertainty as to
how well photos can see but hunting fish
Turtles and crustaceans in the dark
Muddy Waters of the Amazon it is certain
that they do not rely on eyesight
an enlarged hump on their heads helps
Focus their sonar and an elongated snout
enables the dolphin to extract food from
hiding places in Hollow logs or submerge
thickets of vegetation
however these specialized adaptations
have come at a cost
speed
river dolphins are far slower than their
distant relatives in the oceans but
being slow does not disadvantage the
boto because within the Amazon it has no
natural predators
no predators that is except for man
traditionally Amazonian tribes protected
the boto believing them to be
semi-divine beings capable of
shape-shifting into human form
today industry and fishing threatened
the boatos habitat and the food source
they depend on to survive
climate change is another threat placing
an additional strain on fish stocks and
bringing unpredictability to the
Amazon's annual floods
unable to survive in salt water the
Amazon River dolphin has nowhere else to
go with the population of this
mysterious species difficult to
determine the only short way of
protecting them is the preservation of
the Amazon's precious River ecosystems
[Music]
[Applause]
[Music]
rainforests are believed to contain more
than half of all the plant and animal
species on Earth
as well as countless others waiting to
be discovered
in the case of the Amazon we have seen
the Anaconda the sloth
the Cayman
the tarantula
and the boto dolphin
[Music]
[Music]
thank you
[Music]
yet the influence of the Amazon
stretches far beyond its borders
considered the lungs of the planet it
produces around 20 percent of the
world's oxygen and stops greenhouse
gases from entering the atmosphere
but at current rates of deforestation in
as little as 50 years the vast
Wilderness of the Amazon May no longer
exist
[Music]
foreign
[Music]
conservation efforts have been
successful in reducing deforestation but
the Amazon is still shrinking the planet
needs its lungs now more than ever and
greater protection is required to
sustain the Amazon in order for it to
continue
sustaining us
[Music]
thank you
