Scientific classification

• Kingdom: Animalia (animals)
• Type: Chordata (chord)
• Class: Mammalia (mammals)
• Order: Pilosa (edentates)
• Family: Myrmecophagidae (anteaters)
• Genus: Myrmecophaga (giant anteaters)
• Species: Myrmecophaga tridactyla (giant anteater)

Myrmecophaga is a monotypic genus, at least among extant species. The term "tridactyla" (meaning "three-toed") describes an animal whose hand typically has three well-developed claws, while the claws on its fourth and fifth fingers are either completely absent or greatly reduced. This genus may contain a number of extinct species, even though none have been officially named.

Common names include large anteater, three-toed anteater, and ant bear.

The pygmy sloth, whose common ancestor lived more than 55 million years ago, is one of the closest relatives of the giant anteater!

Range of distribution

Geographical distribution

Neotropical species that inhabit low altitudes include giant anteaters. It is widely distributed from Honduras in the north to Bolivia and northern Argentina in the south, spanning southern Central America and northern Latin America. The three-toed anteater was formerly found in Guatemala, Uruguay, El Salvador, southern Belize, and Costa Rica, but it is currently thought to be extinct in these nations.

Habitat

A wide range of environments, such as marshes, dry and wet forests, savannas, and grasslands, are preferred by giant anteaters. They select isolated, well-sheltered areas for naps. Large anteaters can occasionally be found in agricultural and populated areas.

• Habitat areas: tropical
• Terrestrial biomes: wetlands, forests, savannas

Characteristic features

Appearance

The largest of all anteater species, three-toed anteaters have a distinct morphology. They have a tubular muzzle, a sleek skull with an extended rostrum, small ears, and narrow eyes. The massive, shaggy tail almost matches the length of the body in length.

Unlike other anteater species, this one has a tail that is covered in long, stiff hairs and is not prehensile.

The giant ants have coarse, thick fur. Instead of having an undercoat to keep them warm, they have bristly short hair on their shoulders and longer hair, which is arranged in a structure akin to a horse’s mane, on their legs and tail.

The paws have five short claws, three of which are very pointed and elongated on the front. Muravedes walk with their big claws bent to the side, leaning on the wrists of their front paws.

There are no teeth in large ants. Thin and firmly compressed mediolaterally are long dentists. A thin tongue with a spike-shaped ledge can be stuck 61 centimeters outside the mouth.

Coloring

The majority of the body is covered in dark brown fur, with striking long, triangular black stripes with white edges. These stripes begin just below the ears, cover the throat, and continue diagonally back above the shoulders before tapering to the middle of the body in the back.

With two black stripes above the wrists and above the claws, the powerful forelimbs are primarily white. Long tail with a consistent brown hue.

Size

Just by size, giant anteaters can be easily distinguished from the other two genera of anteaters. Length of head and body: 100–130 cm; length of muzzle: 45 cm; length of tail: 65–90 cm; average foot size: 16.5 cm. From tip of nose to tail tip, the total length of the body can reach 230 cm. The range of body weight is 18–39 kg. The external anatomy of three-toed anteaters is nearly indistinguishable from that of adult females, and they do not display sexual dimorphism.

Lifestyle and behavior

Large ants are four-legged, terrestrial insects that hardly ever climb trees. However, they can swim very well and effortlessly across large rivers. During normal movement, their hind limbs exhibit a plantigrade position, while their forelimbs are typically described as "knuckle walking."

Giant anteaters sleep for up to 16 hours a day, or nearly 67% of their waking hours!

The giant anteater’s body temperature is 32.7 °C. The metabolic rate is only 34% of the anticipated value determined by body mass, which is extremely low. This explains the giant anteater’s slowness.

But the animal’s coarse hair and use of a large, bushy tail as a backup method of thermoregulation also contribute to its low thermal conductivity. With a lower limit of thermoneutrality of 15.0 °C, the giant anteater is a capable thermoregulator over a wide range of environmental temperatures due to its large body mass, low thermal conductivity, and wide metabolic range.

Large anteaters’ daily activities are impacted by temperature. Although these animals are mostly nocturnal—especially in extremely hot weather—they are frequently active during the day in isolated locations and on cool days.

When it sleeps, the massive anteater folds its enormous tail around itself to stay warm or spreads it wide open to let in the sun’s rays. Bathing is frequently linked to the desire to cool off or to exterminate termites and ants.

If at all possible, giant anteaters will evade danger. They will use their strong claws to defend themselves when they rear up, using their large tails to support their weight.

Social structure

Except during the mating season and while the females are caring for their young, giant anteaters are solitary creatures most of the time. Instead of creating long-term nests or resting areas, they just roam their own territories.

The typical home range is between 2.7 and 11.9 square kilometers. There is a great deal of overlap between individual territories; densities can approach two animals per square kilometer. In some places, higher densities are linked to an abundance of resources, the lack of natural predators (mainly jaguars), human hunting, and traffic fatalities.

During the breeding season, a large number of females and a smaller number of males will return to their natal sites.

Male-to-male antagonistic interactions, which can range from serious fights to circling, are frequently seen, suggesting that giant anteaters are territorial. Large anteaters may use tree scratching as a means of communication with other members of their own species, or it may be a stress response brought on by fires or other human disturbances.

Diet

The three-toed anteater feeds almost exclusively on termites and ants, though it will sometimes eat insects, beetle larvae, or a European honeybee that has established a hive inside a termite nest.

With its agile, sticky tongue, the three-toed anteater can capture up to 30,000 ants or large to medium-sized termites in a single day. Geographically and seasonally, the percentage of insects eaten varies; in drier habitats and during the dry season, termites make up the majority of the diet.

By feeding for brief periods of time in one location and then moving to another nest, the giant anteater is able to reduce the impact of the chemical and physical defense mechanisms of termites and ants. It takes only 38 seconds to finish eating one insect. Furthermore, the long hair and thick skin of three-toed anteaters shield them from ant bites.

This species’ chewing mechanism is distinguished by its fast food transit and quick tongue extension-retraction cycles (up to 160 cycles per minute), along with nearly constant swallowing. The prey moves forward, rubbing against transverse ridges running along the palate, after retracting the tongue into the mouth.

Despite being nearly blind, great anteaters use their keen sense of smell to locate termites and ants. The animals conserve energy by having a very slow metabolic rate and a low body temperature in comparison to other mammals because their prey has a low energy content.

Rarely do these animals consume alcohol. They get their water from the moisture left on plants after rain and from tearing juicy tree fruits with their sharp claws.

Reproduction

Breeding season

Even if a female isn’t responsive, males will still aggressively pursue them. Males use their extraordinary sense of smell to identify chemical cues that indicate a female’s reproductive status. Estrus cycles last between 47 and 62 days, and they happen roughly every 7 weeks. Cycles do not follow a seasonal pattern. The female lies on her side as the male positions himself over her during sexual contact. Throughout the course of roughly three days, copulations can happen multiple times.

Usually, gestation lasts 170-190 days. Although it is possible for animals to reproduce year-round, there is evidence that courtship and giving birth in captivity follow seasonal patterns. Researchers have found evidence of delayed implantation in giant anteaters, documented births that do not match gestational periods, and repeatedly observed courtship in January.

Development of cubs

Typically, females give birth to a single offspring per year, weighing between 1.1 and 1.6 kg at birth. After a week, the baby’s eyes start to open after being born blind. This species shows intense parental care; lactation lasts six months, and mothers carry their young on their backs for six to nine months before the female becomes pregnant again. Typically, nine months elapse between successive births.

After two to four years, offspring typically reach sexual maturity. In the second half of their second year of life, young animals begin to grow quickly, and it takes them at least three years to reach their full size in the wild.

An amazing animal and a marvel of nature is the Giant Muraviede, also known as the anteater. By regulating insect populations, this gentle giant—not to be confused with a giant—maintains the balance of ecosystems through its remarkable feeding habits and unique appearance. Its long snout and specialized tongue allow it to adapt to its surroundings perfectly, making it a remarkable example of how highly specialized species can be created by nature.

Conservation status

Since giant anteaters are found throughout much of the world, from Honduras to northern Argentina, it is unlikely that they will go extinct anytime soon. Loss of habitat is this species’ biggest threat. Fires are a major threat to three-toed anteaters because they are omnivores and often burn sugar cane plantations before harvest.

Domestic dogs, collisions with vehicles on the highway, sport hunting and hunting for food – all this also negatively affects the populations of large anteaters. Add to this a very specific diet, low reproductive rates, slowness and susceptibility to climate change, and you get a "vulnerable species" on the IUCN Red List.

Protected corridors linking dispersed animal populations could guarantee the preservation of the gene pool of three-toed anteaters, which is another area of concern.

The enormous muraviede is an amazing animal that perfectly embodies the wonders of the natural world. Because of its distinct characteristics and behavior, it stands out from other animals and piques the interest of both scientists and animal enthusiasts.

This species is crucial to the ecosystem because it maintains a balance between termite and ant populations. Its capacity to flourish in harsh conditions serves as a reminder of wildlife’s adaptability and resiliency.
