Peru is one of the world's most biodiverse countries, with habitats ranging from the Pacific coast and dry forests to the high Andes and Amazon rainforest. That diversity also includes many species facing serious conservation pressure from habitat loss, hunting, wildlife trafficking, pollution, fisheries interactions, infrastructure, and climate change.
This updated list uses “endangered animals” in the broad, everyday sense of species at risk. In the formal IUCN Red List system, the threatened categories are Vulnerable (VU), Endangered (EN), and Critically Endangered (CR). The 20 animals below are all globally threatened species recorded in Peru, but their exact categories are not all the same.

Peru's threatened wildlife occurs across very different ecosystems, so conservation priorities vary from species to species.
Andean Bear
The Andean bear, also called the spectacled bear, is the only living bear native to South America. Peru contains important habitat for the species in Andean forests and high-elevation ecosystems. It is globally listed as Vulnerable.
Its main pressures include habitat loss and fragmentation as agriculture, roads, settlement, and other land uses expand. Conflict with people can also lead to retaliatory killing when bears enter farms or are blamed for livestock or crop damage.
Andean Condor
The Andean condor is one of the largest soaring birds in the world and a powerful symbol of the Andes. Its current global category is Vulnerable rather than Critically Endangered, which corrects a claim in the previous version of this article.
Condors are threatened by deliberate poisoning, persecution, contaminated carcasses, and their naturally slow reproduction. Because adults live a long time and raise young slowly, population losses can take decades to replace.
Andean Cat
The Andean cat is one of South America's rarest wild cats and is listed as Endangered. It lives in high-elevation Andean landscapes and depends on healthy mountain ecosystems and sufficient prey.
Threats include habitat degradation, reduced prey populations, and persecution. Conservation is complicated by the cat's low density and the remote terrain it inhabits.
Giant Anteater
The giant anteater is the largest living anteater and is globally Vulnerable. It occurs in several South American habitats and is threatened in different parts of its range by habitat loss, burning, hunting, and road mortality.
Its slow reproductive rate makes population recovery difficult when adult mortality becomes high.
Amazon River Dolphin
The Amazon river dolphin, or boto, is a freshwater cetacean found in the Amazon basin, including Peruvian waters. It is globally Endangered.
Major threats include accidental capture in fishing gear, deliberate killing in some fisheries, mercury and other pollution, and changes to river systems caused by dams and development.
Yellow-Tailed Woolly Monkey
The yellow-tailed woolly monkey is endemic to Peru and is one of the country's highest-priority primates. The currently accepted scientific name is Lagothrix flavicauda; older sources may use Oreonax flavicauda.
It is Critically Endangered. Extensive clearing and fragmentation of montane forest, together with hunting, have greatly reduced and isolated its habitat.
White-Bellied Spider Monkey
The white-bellied spider monkey is an Endangered primate found in parts of the western Amazon, including Peru. Spider monkeys need large areas of connected forest and are especially vulnerable to habitat fragmentation.
Hunting is another major pressure because spider monkeys are large-bodied, slow-reproducing primates.
Bald Uakari
The bald uakari is a distinctive Amazonian monkey with a short tail and a bright red face. It is globally Vulnerable and occurs in flooded and seasonally flooded forests in the western Amazon.
Forest loss and hunting can reduce local populations, particularly where access to remote forests increases.
Goeldi's Monkey
Goeldi's monkey is a small Amazonian primate distributed in Peru and neighboring countries. It is globally Vulnerable and often occurs at naturally low densities.
Habitat conversion and fragmentation are major concerns, especially where forests are cleared for farms, roads, or settlements.
Mountain Tapir
The mountain tapir is the smallest living tapir and one of the most threatened large mammals of the northern Andes. It is listed as Endangered.
It depends on montane forest and high-Andean habitats that are increasingly fragmented. Hunting and land conversion further reduce already isolated populations.
Giant Otter
The giant otter is an Endangered freshwater predator associated with Amazonian rivers, lakes, and wetlands. Peru still supports important populations in protected landscapes.
Historic hunting caused severe declines. Today, habitat disturbance, pollution, conflict with fisheries, and degradation of waterways remain important threats.
Marine Otter
The marine otter lives along rocky Pacific coasts of Peru and Chile and is one of the few otters strongly adapted to marine environments. It is globally Endangered.
Coastal development, disturbance, accidental capture in fishing gear, pollution, and competition or conflict around fisheries can affect local populations.
Zuniga's Dark Rice Rat
Zuniga's dark rice rat is one of the most poorly known mammals on this list. It is associated with the coastal lomas ecosystem near Lima and is listed as Critically Endangered.
The species has not been reliably recorded for decades despite searches, while its known habitat has been heavily altered by urban expansion and other land-use change.
Lake Titicaca Water Frog
The Lake Titicaca water frog is a large aquatic frog endemic to the Lake Titicaca basin shared by Peru and Bolivia. It is listed as Endangered.
Pollution, harvesting, introduced species, disease, and climate-related changes all affect the species. Its loose, highly folded skin is an adaptation to life in cold, oxygen-poor high-altitude water.
Peruvian Plantcutter
The Peruvian plantcutter is an endemic bird of Peru's dry coastal and northwestern habitats. Its current global category is Vulnerable, correcting the previous version of this article, which described it as Endangered.
Its remaining habitat is fragmented, and continued clearing or degradation of dry forest and scrub can isolate populations further.
White-Winged Guan
The white-winged guan is endemic to northwestern Peru and was once feared extinct before being rediscovered in the 1970s. Conservation breeding, reintroduction, protected areas, and local conservation work have helped improve its situation.
Its current global category is Endangered. Habitat destruction and hunting remain the main long-term threats.
Humboldt Penguin
The Humboldt penguin breeds along the Pacific coast of Peru and Chile and is globally Vulnerable. It depends on the productive Humboldt Current ecosystem.
Changes in food availability, fisheries interactions, disturbance at breeding sites, and strong oceanographic events can all affect breeding success and survival.
Giant Armadillo
The giant armadillo is the world's largest living armadillo and occurs in the Peruvian Amazon. It is globally Vulnerable.
Deforestation, hunting, road expansion, and wildlife trafficking are major threats. Because it occurs at low densities and is mostly nocturnal, population declines can be difficult to detect.
Blue Whale
The blue whale is the largest animal known to have lived on Earth. Some blue whales occur or migrate through waters off Peru, and the species is globally Endangered.
Commercial whaling caused historic population collapse. Today, ship strikes, entanglement, underwater noise, and changing ocean conditions remain significant conservation concerns.
Hawksbill Sea Turtle
The hawksbill sea turtle is globally Critically Endangered and occurs in tropical and subtropical waters, including the eastern Pacific region.
Historic and illegal trade in its patterned shell, accidental capture in fisheries, loss of coral-reef habitat, and coastal development have contributed to its decline.
Why So Many Peruvian Species Are Threatened
The causes differ between ecosystems, but several pressures appear repeatedly:
Deforestation and habitat conversion: especially in Amazonian and Andean forests.
Habitat fragmentation: roads, farms, settlements, and infrastructure can isolate populations.
Hunting and wildlife trafficking: particularly serious for large mammals, primates, and some birds.
Pollution: affects freshwater and marine species through mining, plastics, chemicals, and sewage.
Fisheries interactions: can cause bycatch or reduce food availability for marine wildlife.
Climate change: can intensify pressure on glaciers, mountain habitats, rivers, coasts, and ocean food webs.
Where Peru Protects Threatened Wildlife
Peru's national protected-area system includes forests, wetlands, mountains, coastlines, and other habitats important to threatened species. However, protected areas alone are not enough. Many species move across reserve boundaries or survive in landscapes where local communities, farms, roads, and towns are also present.
Effective conservation therefore depends on habitat protection, enforcement against illegal wildlife trade and hunting, restoration, scientific monitoring, and cooperation with communities living near wildlife habitat.

Frequently Asked Questions
What is the most endangered animal in Peru?
There is no single scientifically correct answer because many species are assessed separately and face different risks. Among the animals in this list, the yellow-tailed woolly monkey, Zuniga's dark rice rat, and hawksbill sea turtle are classified as Critically Endangered globally.
Is the Andean bear endangered?
The Andean bear is globally classified as Vulnerable, not Endangered. Its populations are declining in parts of its range because of habitat loss, fragmentation, and conflict with people.
Is the Andean condor critically endangered?
No. The Andean condor is currently classified as Vulnerable globally. It is still a conservation concern because its population is declining and the species reproduces very slowly.
Which endangered animals are unique to Peru?
The yellow-tailed woolly monkey and white-winged guan are notable Peruvian endemics. Other species on this list may occur in Peru and neighboring countries rather than being restricted entirely to Peru.
Why are animals becoming endangered in Peru?
The most common causes include deforestation, habitat fragmentation, hunting, wildlife trafficking, pollution, fisheries interactions, infrastructure development, and climate-related changes.
Does “endangered” always mean the IUCN category Endangered?
No. In everyday language, people often use “endangered” for any species at risk. Formally, the IUCN separates threatened species into Vulnerable, Endangered, and Critically Endangered categories. This article identifies the formal category for each animal.

Final Takeaway
Peru's endangered and threatened animals are not limited to one habitat or one taxonomic group. They include high-Andean mammals, Amazonian primates and river species, coastal birds, amphibians, marine mammals, and sea turtles. The most useful way to understand their risk is to look at each species' formal conservation category, habitat, population trend, and specific threats rather than treating every animal as equally endangered.
