tail. ''Neotamandua'', though, is unlikely to have had a prehensile tail and its feet were intermediate in form between those of the tamanduas and the giant anteater. The species '' Neotamandua borealis'' was suggested to be an ancestor of the latter. Another member of the genus ''Myrmecophaga'' has been recovered from the Montehermosan Monte Hermoso Formation in Argentina and was described by Kraglievitch in 1934 as ''Nunezia caroloameghinoi''. The species was reclassified as '' Myrmecophaga caroloameghinoi'' by S. E. Hirschfeld in 1976. The giant anteater is the most terrestrial of the living anteater species. Its ancestors may originally have been adapted to arboreal life; the transition to life on the ground could have been aided by the expansion of open habitats such as savanna in South America and the availability there of colonial insects, such as termites, that provided a larger potential food source.

Characteristics and adaptations

The giant anteater can be identified by its large size, elongated muzzle, and long bushy tail. It has a total body length of . Males weigh and females weigh , making the giant anteater the biggest extant species in its suborder. The head of the giant anteater, at long, is particularly elongated, even when compared to other anteaters. Its tubular snout, which ends in its tiny mouth opening and nostrils, takes up most of its head. Its eyes and ears are relatively small. It has poor eyesight, but its sense of smell is 40 times more sensitive than that of humans. Even for an anteater, the neck is especially thick compared to the back of the head, and a small hump is found at the back of the neck. The coat is mostly greyish, brown or black and salted with white. The forelimbs are white, with black bands around the wrists, while the hindlimbs are dark. Thick black bands with white outlines stretch from throat to shoulder, ending in triangular points. The body ends in a brown tail. The coat hairs are long, especially on the tail, which makes the tail look larger than it actually is. A stiff mane stretches along the back. The bold pattern was thought to be

. While adult males are slightly larger and more muscular than females, with wider heads and necks, visual sex determination can be difficult. The penis and testes are located internally between the rectum and urinary bladder in males, and females have a single pair of mammary glands near the armpits. The giant anteater has broad ribs. Despite its specific name, ''tridactyla,'' meaning three fingers, it has five toes on each foot. Four toes on the front feet have claws, which are particularly elongated on the second and third digits. It walks on its front knuckles similar to

Feeding anatomy

Myrmecophaga tridactyla -Detroit Zoo, Michigan, USA-8a

The giant anteater has no teeth and is capable of only very limited jaw movement. It relies on the rotation of the two halves of its lower jaw, held together by a ligament at the tip, to open and close its mouth. This is accomplished by its chewing muscles, which are relatively underdeveloped. Jaw depression creates an oral opening large enough for the slender tongue to flick out. It is typically long and is triangular posteriorly, rounded anteriorly, and ends in a small, rounded tip. The tongue is covered in backward-curving papillae and coated in thick, sticky saliva secreted from its enlarged salivary glands. The tube-like rostrum and small mouth opening restrict the tongue to protrusion-retraction movements. During feeding, the animal relies on the orientation of its head for aim. The tongue can reach up to , longer than the length of the skull, and move in and out around 160 times per minute (nearly three times per second). The anteater's tongue has little to no attachments to the hyoid and this is what allows it to flick its tongue at such distances and speed. The long sternoglossus muscle, which is formed by the fusion of the sternohyoid and the

hyoglossus The hyoglossus, thin and quadrilateral, arises from the side of the body and from the whole length of the greater cornu of the hyoid bone, and passes almost vertically upward to enter the side of the tongue, between the styloglossus and the in ...

, is directly anchored to the sternum. The hyoid apparatus is large, V-shaped and flexible and supports the tongue as it goes in and out of the mouth. The buccinators allow it to slide back in without losing attached food and tighten the mouth to prevent food from escaping as it extends. When retracted, the tongue is held in the

in Brazil. The animal is particularly vulnerable to fires due to its slow movement and flammable coat. Human-induced threats include collision with vehicles, attacks by dogs, and destruction of habitat. One study of anteater mortality along roads found that they are likely to become roadkill on straight roads with native vegetation along the side. A 2018 study in Brazil found that: (1) fragmentation of habitat could be more detrimental than road mortality, (2) 18–21% of suitable anteater habitat was below minimum patch size, (3) 0.1–1% of its distribution was maximum road density, (4) 32–36% of the anteater's range represented critical areas for its survival and (5) more conservation opportunities existed in the north of the country.

Behavior and ecology

The giant anteater may use multiple habitats. A 2007 study of giant anteaters in the Brazilian Pantanal found the animals generally forage in open areas and rest in forested areas, possibly because forests are warmer than grasslands on cold days and cooler on hot days. Anteater may travel an average of per day. Giant anteaters can be either diurnal or

nocturnal Nocturnality is an animal behavior characterized by being active during the night and sleeping during the day. The common adjective is "nocturnal", versus diurnal meaning the opposite. Nocturnal creatures generally have highly developed sens ...

. A 2006 study in the Pantanal found those anteaters to be mostly nocturnal: they are most active during nighttime and early morning, and retire as the temperature rises. On colder days, they start and end periods of activity earlier, shifting them into daylight hours, and may become diurnal. Diurnal giant anteaters have been observed at Serra da Canastra. Nocturnality in anteaters may be a response to human disturbances. Giant anteaters typically rest in dense brush, but may use tall grass on cooler days. They carve a shallow cavity in the ground for resting. The animal sleeps curled up with its bushy tail folded over its body. The tail serves both to conserve body heat and as

. One anteater was recorded sleeping with its tail stretched out on a sunny morning with an ambient temperature of ; possibly it was positioned this way to allow its body to absorb the sun's rays for warmth. Giant anteaters are good swimmers and are capable of moving through wide rivers. They have been observed to bathe. They are also able to climb and have been recorded ascending both termite mounds and trees while foraging. One individual was observed holding onto a branch with its feet just touching the ground.

Spacing

Giant anteaters' home ranges vary in size depending on the location, ranging from as small as in Serra da Canastra National Park, Brazil, to as large as in Iberá Natural Reserve, Argentina. Individuals mostly live alone, except for females that nurse their young and males courting females. Anteaters communicate their presence, status, and sexual condition with secretions from their anal glands. They also advertise their presence to other individuals though tree markings and urine. They appear to be able to recognize each other's saliva by scent. Females appear to be more tolerant of females than males are of males, leading to greater overlap in female home ranges. Males are more likely to engage in

eat mainly termites, which occur in high density on the grasslands. At Serra da Canastra, anteaters switch between eating mainly ants during the wet season (October to March) and termites during the dry season (May to September). Anteaters track prey by their scent. After finding a nest, the animal tears it open with its long fore claws and inserts its long, sticky tongue to collect its prey. An anteater spends one minute on average feeding at a nest, visiting up to 200 nests in one day and consuming as many as 30,000 insects. The anteater may be driven away from a nest by the chemical or biting attacks of soldiers. Some termite species rely on their fortified

Reproduction and parenting

Giant anteaters can mate throughout the year. During courtship, a male consorts with an estrous female, following and sniffing her. Male and female pairs are known to feed at the same insect nest. While mating, the female lies on her side as the male crouches over her. A couple may stay together for up to three days and mate several times during that period. Gestation lasts around 190 days and ends with the birth of a single pup, which typically weighs around . Females give birth standing upright. Pups are born with eyes closed and begin to open them after six days. The mother carries its dependent pup on its back. The pup's black and white band aligns with its mother's, camouflaging it. The young communicate with their mothers with sharp whistles and use their tongues during nursing. After three months, the pup begins to eat solid food and is fully weaned by ten months. The mother grooms her offspring during rest periods lasting up to an hour. Grooming peaks during the first three months and declines as the young reaches nine months of age, ending by ten months. The decline mirrors that of the weakening bond between mother and offspring; young anteaters usually become independent by nine or ten months. Anteaters are sexually mature in 2.5–4 years.

s and pumas and typically flee from danger by galloping, but if cornered, will rear up on their hind legs and slash at the attacker. The front claws of the giant anteater are formidable weapons, capable of killing a jaguar. The giant anteater is a host of the Acanthocephalan intestinal parasites '' Gigantorhynchus echinodiscus'' and '' Moniliformis monoechinus''.

Interactions with humans

Attacks

Although they are shy and typically attempt to avoid humans, giant anteaters can inflict severe wounds with their front claws and have been known to seriously injure or kill humans who corner and threaten them. Between 2010 and 2012, two hunters were killed by giant anteaters in Brazil; in both cases, the hunters were agitating and wounding cornered animals and the attacks appeared to be defensive behaviors. In April 2007, an anteater at the Florencio Varela Zoo mauled and killed a zookeeper with its front claws. The animal in question, a male named Ramon, had a reputation for aggressiveness.

foil to the jaguar, as well as a humorous figure due to its long snout. In one Shipib tale, an anteater challenged a jaguar to a breath-holding contest under water, which the jaguar accepted. After the two removed their pelts and submerged, the anteater jumped out of the water and stole the jaguar's pelt, leaving the jaguar with the anteater's pelt.
