Description
One of the smaller sized armadillos
Get their name from the three bands found on their armor that help them roll into a ball
Can reach lengths up to 12 in and weigh around 3 lbs
Usually live 15-20 years in the wild
Their bodies are covered in a hard carapace made up of bony plates called scutes
Usually yellow or brownish in color
Made up of keratin just like human fingernails and hair
This armor also covers the top of the head, tail, and all their limbs
It is not attached to the skin on the side of the body which gives the armadillo enough room for all their body parts to be protected when they roll up
They have a very powerful nose which helps them find food, avoid predators and identify other armadillos
Due to their nocturnal nature, they don’t have very good eyesight
Their ears are small but very powerful
Their tongue is pink in color and very long and sticky like other insect eaters
The belly is comprised of soft, hairy skin
They have very powerful legs and claws that help them dig and open dead trees to eat the insects inside
Their front feet have four separate toes each with a claw
However, the three middle toes on the back feet have fused together and look like a hoof
Their tails are short and thick
Habitat
Found in areas of dry vegetation like grasslands, marshes and open forests
Range includes central and eastern Bolivia, the Mato Grasso of Brazil, the Chaco region of Paraguay, and northern and central Argentina
Behavior
Southern three banded armadillos are nocturnal and forage during the night
They are active year round because their shells are awesome at trapping heat so they can keep warm during the winter
They are insectivores
Typically eat ants, termites or beetle larvae
May also eat ripe fruit every so often
Unlike other armadillo species, southern three banded armadillos do not typically dig their own burrows and often live in burrows that were dug and abandoned by Giant Anteaters or will live above ground
When threatened by predators, the armadillo will curl up but not totally shut the shells all the way
Then when the predator sticks its nose or paw into the gap to get at the underbelly, the armadillo will snap its shell shut and hurt the predator
Predators include coyotes, bobcats, mountain lions, some raptors, domestic dogs and humans
Typically solitary but may gather in groups if its is cold
Also come together to breed
There is no defined breeding season but babies are typically born from November-January
Gestation usually lasts four months
One baby is born at a times
Babies are born bind and about the size of a golf ball but quickly develop the ability to walk and close their shells
They nurse for about two and a half months and then at about 72 days, they become fully independent
Fun Facts
The only mammal that can totally curl up into a ball to protect itself
Known as volvation
Related to sloths and anteaters
Armadillo is a Spanish word that translates to “Little armored one”
Also really fast runners
I once saw one at the Lincoln Park Zoo that was running around in circles at high speed
The pattern on their shells are unique just like human fingerprints

Description
Medium sized opossum
Gets its name from the fact it can store a lot of fat in its tail which can reach lengths of 5-5.7 in and a diameter of up to .39 in where it attaches to the body
The size of their tail varies according to food availability
Body can reach lengths of 4.3-5.4 in
Covered in gray to light brown fur
Sides and belly are lighter in color
Legs are white in color
Its back legs reach the length of .67 inches
Has black rings around both eyes
Body color can vary depending on their environment
Its ears are relatively big and can reach length of .91 in
Habitat
Found in a variety of habitats including cloud forests and chaparrals
Range is west of the Andes mountain range in Western Chile
Behavior
Elegant fat-tailed mouse opossums are primarily crepuscular
During the day they will go into torpor which is like a shorter hibernation
This allows them to reduce their food and energy requirements
Speaking of food, they primarily eat arthropods and larvae as well as fruits, small vertebrates and carrion
These possums live in nests that they built or ones abandoned by other animals
They can be found in tree hollows and under rocks or roots since the possums are good at being arboreal which means tree dwelling and terrestrial which mean earth dwelling
Like most possums, they are very good climbers and can use their prehensile tails to hang onto branches
Only one individual lives in these nests
Predators they need to avoid are the culpeo fox, great horned owls and burrowing owls
Home ranges can be up to 14,890 square feet in the summer and can shrink to about 8,410 square feet in the winter
Breeding season is September-March
Females can have 1-2 litters during breeding season
Up to 17 embryos can be produce but the actual number depends on the number of working nipples which is typically 10-13
Fun Facts
First described by English naturalist George Robert Waterhouse in 1839
They are marsupials but the females do not have pouches

Description
Medium sized primate about the size of a housecat
Get their name from their bald heads which are usually bright red
Can reach weights between 2.75 and 3.45 kgs and lengths between 15-22.5 inches
Males usually average about 17.9 inches in length and females average about 17 inches
Bald uakaris can live between 15-20 years in the wild and up to 30 years in captivity
Their heads are bright red due to a combination of thinner epidermis and more capillaries in their face
The red color is a sign of health, so the redder the better and if their face is pale, it means they are sick
This is commonly due to malaria
They also have very sharp fangs which are good at ripping apart fruit
Their bodies are covered in a long, shaggy coat that comes in several variations of blonde, orange, brown or red
This is also a good way to tell the subspecies apart because they each have different coat colors
Like most monkeys, bald uakaris typically have long legs,arms, toes, and fingers
Unlike other monkeys though, they have a very short tail that only reaches 5 inches in length
Habitat
Bald uakaris are found in tropical forests in the Amazonian lowlands that are called floodplain forests or varzea forests since they flood seasonally
They can also be found in other wooded areas
Their favorite habitats are ones with aguaje palm trees
Their range is between the Yavari and Ucayali rivers in eastern Peru and Western Brazil
There used to be some in southern Colombia but no longer due to deforestation
Behavior
Bald uakaris are diurnal and active during the day
During the rainy season of December-May, bald uakaris are arboreal or tree dwelling so they can stay out of the floodwaters
However, during the dry season of August-November, they spend more time on the ground
Bald uakaris are herbivores and frugivores which means they eat plants and fruits
Their diet varies depending on the season
In the wet season, they eat a lot of leaves and fruits since they are in the trees most of the time
During the dry season, they eat fallen leaves and fruit, seeds and roots they forage off the forest floor
Bald uakaris are typically found in troops of 30 individuals but can be found in bigger groups that can have 100 members in them, especially when they sleep
These troops typically have a home range of 2 square miles and can travel up to 3 miles a day
During the dry season, they will often go down to the forest floor and forage in groups of 10
Bald uakaris typically get around by using all four limbs but they can also walk and jump on two legs.
Breeding season for bald uakaris is usually between October and May and the gestation period is 6 months
Females give birth to one baby every two years
The babies start to wean at about 5 months old when they add fruit to their diets and eventually grow up
Males will eventually leave their birth troop while females will stay with their birth troop
Bald uakaris have interesting communication methods which include vocalizations, facial expressions, pheromones, and body language.
Their bald heads are very useful for communication and they make up to 10 different facial expressions
Fun Facts
Also known as the bald-headed uakari, red uakari, or scarlet fever uakari
They wag their tails when excited
Their jaws are very strong and combined with their fangs, can crack open some kinds of nuts that other monkeys cannot
The babies are born with gray faces that eventually turn red

Description
Semiaquatic rodent of unusual size found in Central and South America
Capybaras can reach heights of 1.7-2 feet at their shoulders and lengths of 3.48-4.4 feet
Can reach weights between 77 and 146 pounds and the average is about 108 pounds with the females usually being slightly heavier than the males
They can live up to 8-10 years but oftentimes they only live about four years in the wild due to predation
Their predators include: jaguars, pumas, ocelots, eagles, caimans, and green anacondas
Their heavy, barrel shaped body is covered in coarse, short fur
The fur is reddish-brown on the tops and sides and becomes yellowish-brown underneath
It is also designed to dry quickly when the capybara comes out of the water
Capybaras have short heads with a blunt snout with nostrils on the end of it
Their eyes and ears are found near the top of their heads just like hippos which allows them to keep the rest of their bodies submerged and poke those body parts above the water to see what’s going on around them
Just like most rodents, their two front teeth are constantly growing but are ground down by use
Capybaras have two scent glands, one of which is found on top of their snouts and known as a morrillo
Males have a much more pronounced morrillo and they scent mark things more often than the females
Their legs are short and sturdy with the back ones being slightly longer than the front ones
At the end of their legs they have webbed toes with hoof like claws on the end to help with swimming and climbing up river banks and out of the mud
They have four toes on the front and three toes on the back
The tail is short and vestigial
Their other set of scent glands are anal scent glands and on the males they are lined with detachable hairs
These hairs are covered with a crystalline form of scent secretion that lasts longer than other forms of scent and are tasted by other Capybaras that come upon them
Capybaras mark things with scent by rubbing their morrillos on them or walking over plants and marking them with their anal scent glands
Habitat
Found in lowland areas near bodies of water
Their habitat includes rainforest lakes and rivers, marshes, brackish wetlands, swamps as well as seasonally flooded grasslands and savannas
Range includes Panama, Colombia, Peru, Venezuela, Argentina, Uruguay, Paraguay, Brazil, Bolivia, Ecuador, and Guyana
Behavior
Capybaras are crepuscular and are usually most active during morning and evening
However, if they feel threatened, then they are active during the night
During the day, they will wallow in water and mud to keep cool or will doze on the banks or in the water
Then around evening, they emerge from the water to graze
Capybaras are herbivores and are very selective about the plants they eat
During the wet season, they primarily eat grass and aquatic plants while also supplementing their diets with fruit and bark
An adult capybara can eat 6 to 8 pounds of grass per day
During the dry season, capybaras eat a greater variety of plants including reeds, grains, melons and squashes
Capybaras are also coprophagous which means they eat their own poop
They do this for the beneficial gut bacteria which helps them break down the cellulose they consume as well as getting as many nutrients and vitamins out of their food as possible
Capybaras also regurgitate their food to chew it up better just like cows and other ruminants
They are often found in groups of 10 but can sometimes be solitary
These groups consist of one dominant male, one or more females, one or more subordinate males, and several juveniles
During the dry season, these groups can expand to 50-100 individuals due to them gathering around water sources
Capybara groups have very stable home ranges and while they get along well with individuals not in their groups, they still chase off the intruders
Capybaras do not have a set breeding period but the peak is usually from April-June or October-November depending on where they live
Males and females can choose who they mate with and since breeding takes place in water, if the female doesn’t like what’s going on, they can dive underwater or leave the water
The dominant male gets to mate more often than the subordinates but the subordinate males overall mated with more females
Gestation lasts 130-150 days after which four pups are born on average
However, the number can range between 1 and 8 pups
After giving birth on land, the females rejoin the group a few hours later and the babies will join as soon as they are mobile which is only a few hours after being born
The pups are able to eat grass within a week but will often suckle from their mom as well as other females in the group until they are weaned at 16 weeks old
Other members of the group will also help take care of the pups along with their mothers
Capybaras communicate through scent marking and several types of sounds such as: whistles, grunts, barks, and squeals
Fun Facts
The two parts of their scientific name Hydrochoerus hydrochaeris come from Greek and translate to water pig/hog
Their common name comes from the Tupi language spoken in Brazil and means one who eats slender leaves
Closest relatives are the guinea pig and rock cavies but it is also distantly related to chinchillas, agoutis, and nutrias
In the 16th century, the Catholic Church apparently classified the capybara as a fish so that the meat could be eaten on Fridays and during Lent
Fossils of the extinct Pickney’s Capybara were found in San Diego County’s Oceanside
They are farmed for their meat and hides which are used to make leather
Capybaras can’t synthesize Vitamin C in their bodies so they get it from the food they eat
If they don’t receive supplemental Vitamin C, they can develop gum disease which is a sign of scurvy
They can spend up to five minutes underwater

Description
Largest of the four anteater species
Can reach lengths between 6-8 ft which includes their noses and tails
Females weigh 60-104 lbs and Males weigh 73-110 lbs
Body is covered in thick bushy hair that comes in various shades of brown with black stripes that run down to their spine
They also have a mane running down their spine
Their front legs are white and they have a large bushy tail
Their eyes and ears are very small
The defining characteris tic of the giant anteater is their very long tubular snout with nostrils found on the end of it
In fact, their head reaches a length of 12 inches or 1 foot
Unfortunately, giant anteaters do not have any teeth and they can’t open their mouths very wide
However, they are able to open their mouths just enough for the 2 foot sticky tongue to move in and out to eat the ants and termites
They are able to accomplish this thanks to the rotation of both halves of their lower jaw
Their tongue can extend 18 inches past the length of their snout and it can move in and out of their mouth at 160 times per minute or 3 times a second
Some of their throat muscles and other apparatuses are very specialized and give them the ability to flick their tongue really quickly while also making sure their prey can’t escape once the ants and termites are slurped up
Their necks are very thick and have a hump behind their neck
Another thing giant anteaters are known for are the large claws on their feet they use to break into termite and ant mounds
To preserve their front claws, they tuck them into their palms and walk on their knuckles like gorillas do
Their back claws and feet are more similar to bear claws and feet which means giant anteaters use their back feet normally
When threatened and cornered, either by humans or their predators which are pumas and jaguars, giant anteaters rear up on their hind legs and slash at the attacker with their claws
This can cause serious injury or even death
Giant anteaters have stomachs very similar to gizzards found in birds
Inside there are hardened skin folds and the contractions of the stomach help grind up the ants and termites along with ingested sand and soil
They don’t produce their own stomach acid and instead use the formic acid from the ants and termites they eat
It would be really unpleasant to be digested using acid you naturally create
Giant anteaters normally walk at a slow shuffling pace but if they need to, they can gallop at a pace of 30 mph
They can also climb and swim
Habitat
Found in tropical moist forests, dry forests, savannas, and open grasslands
Range includes most of Central and South America, from Honduras to the Gran or Dry Chaco region of South America and they are no longer found in Uruguay, Belize, El Salvador, and Guatemala
Behavior
Giant anteaters can be both diurnal or nocturnal. If there is more human activity around them, then they are nocturnal. If there isn’t a lot of human activity around them, then they are diurnal
When resting, they usually hide in thick brush and dig out a shallow cavity where they sleep with their tail over their head
They are insectivores
Their diet consists of both ants and termites but depending on their habitat and the season, giant anteaters will either eat more ants or more termites
To find the mounds, giant anteaters use their awesome noses to follow the smell of the ants or termites
Once they reach a mound, they rip it open using their massive claws and start licking up the bugs with their long tongue
They typically spend only a minute at each mound to reduce the chances of the ants or termites attacking them
This means they will visit up to 200 mounds per foraging session and eat up to 30,000 ants or termites a day
Giant anteaters get most of their water from the food they eat though sometimes they may dig for water which creates water holes for other animals
They are usually solitary and come together for mating
Their home ranges vary in size from 2.7 sq km to 32.5 sq km but again it depends on where they live
Males can be territorial and may end up fighting other males that wander into their ranges
Females are not very territorial and tolerate other females
Breeding season is usually between March and May but can take place at any time
Males will follow females around if they are in season and will spend several days together and even eat out of the same mounds during that time
Gestation lasts about 190 days and females give birth to usually one pup while standing upright
After birth, the baby will climb on its mother’s back where it will spend a year or so
During this time, the baby will suckle on the nipples found on their mother’s chest for three-six months and then will be weaned at that point
Finally, the baby will leave its mother at two years of age
Giant anteaters communicate through scent marking from their anal glands and also through urine and marks on trees made with their claws
Fun Facts
Related to sloths and armadillos
Their sense of smell is 40 times more powerful than humans
They have one of the lowest body temperatures for mammals at 91 degrees Fahrenheit
They can eat as many as 30,000 ants or termites in one day
They are not immune to ant and termite bites so they only feed on a mound for a short time before moving on
