Anteaters at a glance

Need to know

• Anteaters lack teeth entirely and instead use an extremely long, sticky tongue to gather insects.
• Their long claws are used to tear open termite mounds and ant nests.
• The giant anteater can eat up to 30,000 ants or termites in one day.
• Silky anteaters are so small and elusive they are rarely seen by humans.
• Tamanduas are sometimes called 'stinkers of the forest' due to their strong scent glands.

About the Anteaters

Anteaters are a unique group of insectivorous mammals known for their exceptional adaptations to consuming ants and termites. Unlike most mammals, anteaters lack teeth, instead using a specialized elongated tongue, which can be more than twice the length of their head, to slurp up insects from nests and tunnels. Found exclusively in Central and South America, anteaters show a remarkable diversity in size, behavior, and ecological roles, ranging from the ground-dwelling giant anteater to the tiny, fully arboreal silky anteater.

All anteaters are part of the order Pilosa, but true anteaters belong to the family Myrmecophagidae (giant anteater and tamanduas). The silky anteater, often grouped with them, is in the family Cyclopedidae but is closely related. Their adaptations include robust forelimbs for digging, prehensile tails in tree-dwelling species, and protective adaptations against insect bites. Unfortunately, habitat loss and hunting have severely impacted some anteater populations, making conservation efforts increasingly important.

Physical characteristics

Size: Silky anteater: 35cm–45cm; Tamanduas: 53cm–88cm; Giant anteater: up to 2.1m including tail. Weight: Silky anteater: 0.4 kg; Tamanduas: 3.5–8.4 kg; Giant anteater: 18–65 kg. Lifespan: Average 14 years in wild (up to 25 in captivity).

• Long tubular snout
• Extremely long sticky tongue
• Powerful, curved foreclaws
• Dense, often bushy tail (especially in giant anteater)
• Coarse or silky fur, depending on species

Notable species

• Giant Anteater (Myrmecophaga tridactyla) — Vulnerable. Grasslands, savannas, forests, and wetlands Regions: Amazon Rainforest, Pantanal, Gran Chaco, Guianas, Central America, Cerrado of Brazil, Eastern Andes foothills.
• Northern Tamandua (Tamandua mexicana) — Least Concern. Lowland and montane forests, secondary growth, woodland edges Regions: Southern Mexico, Central America, Colombia (northwestern), Panama Canal Zone, Costa Rica.
• Southern Tamandua (Tamandua tetradactyla) — Least Concern. Forests, savanna, gallery forest, and scrublands Regions: Brazilian Atlantic Forest, Pantanal, Amazon Rainforest, Savannas of South America, Northern Argentina.
• Silky Anteater (Cyclopes didactylus) — Least Concern. Dense, humid rainforests, especially in vine tangles Regions: Amazon Rainforest, Orinoco Basin, Yucatán Peninsula, Guiana Shield, Coastal Ecuador.

Habitat and range

Original range: Central and South America: forests, savannas, and grasslands from southern Mexico to northern Argentina.

Current distribution: Present throughout much of their original Neotropical range, but extinct from many localities, especially in Central America and coastal Brazil.

Preferred environments: Tropical rainforests, Dry savannas, Wetlands, Gallery forests, Grasslands

Regions: Amazon Rainforest, Pantanal, Gran Chaco, Guianas, Atlantic Forest, Orinoco Basin, Central America, Yucatán Peninsula, Northern Argentina, Eastern Andes foothills

Where to see Anteaters

• Pantanal, Brazil — May to September (dry season). Giant anteaters are most visible foraging in open grasslands or forest edges.
• Costa Rica's rainforests — Dry season (December to April). Look for northern tamanduas climbing trees near forest streams.
• Amazon River Basin — Year-round. With luck, spot silky anteaters at night, tangled in vines.

Behavior and diet

Diet: Primarily ants and termites, occasionally other insects and small invertebrates.

Social structure: Mostly solitary except during mating or mother-offspring pairs.

Communication: Limited vocalizations, rely on scent marking and body language.

• Use long, curved claws to tear open nests and defend against predators.
• Flick tongue rapidly to consume thousands of insects per day.
• Tamanduas and silky anteaters use prehensile tails for climbing.
• Giant anteaters can defend themselves against jaguars using their claws.

Interactions with other animals

• Jaguar (predator): Jaguars occasionally prey on anteaters, especially juveniles, though adults can deliver severe defensive wounds.
• Ants and termites (prey): Anteaters are specialized to feed almost exclusively on these insects.
• Humans (competitive): Humans compete with anteaters through habitat destruction and can pose a hunting threat, especially to giant anteaters.

Conservation

IUCN Red List status: Vulnerable (giant anteater); Least Concern (tamanduas and silky anteater)

Threats

• Habitat loss and fragmentation
• Wildfires and agricultural expansion
• Road mortality
• Hunting and poaching
• Dog attacks

Conservation efforts

• Habitat restoration projects
• Protected area expansion
• Environmental education programs
• Monitoring and relocation programs for road-killed individuals

How to help

• Support organizations protecting South American rainforests and grasslands.
• Reduce consumption of products contributing to deforestation.
• Promote wildlife-friendly road infrastructure in anteater habitats.
• Report sightings to anteater monitoring projects.
• Educate others about the importance of insectivores in ecosystems.

Anteaters facts for kids

Anteaters are cool animals with really long snouts and tongues that help them eat thousands of ants and termites every day! They come in different sizes, from small and furry to big and shaggy, and live in South and Central American forests and grasslands.

• Anteaters have no teeth at all!
• Their tongue can be up to 60 centimeters (2 feet) long.
• Giant anteaters walk on their knuckles, like gorillas.
• A baby anteater rides on its mom’s back for up to a year.
• Anteaters use their big claws to dig into insect nests.
