Have you ever wondered about the ten most endangered animals and how to protect them?
A species is classified as endangered when its population has declined between 50 and 70 percent and as when its population is restricted to less than 250 mature individuals. When a species’ population is this low, its area of occupancy is not considered.
There are now a total of 41,415 species on the IUCN Red List, and 16,306 of them are endangered species threatened with extinction. This is up from 16,118 compared to last year.
If you like, you can also watch the Most Endangered Animals web story.
This includes both endangered animals and endangered plants.
Read on to find out which animals are at the highest risk for extinction and what we can do to protect the 10 most endangered animals in 2023.
#1 Javan Rhinoceros
About Javan Rhinoceros
| Conservation status: Critically Endangered |
| Population: Around 60 |
| Scientific name: Rhinoceros sondaicus |
| Height: 4.6–5.8 feet |
| Weight: 1,984 – 5,071 pounds |
| Length: 10–10.5 feet |

The 10 most endangered animals: Only 67 Javan rhinos are currently estimated to remain in the world, making this critically endangered rhino species one of Earth’s most threatened large mammal species. They’re confined to one park on the extreme southwestern tip of the Indonesian island of Java
Only 67 Javan rhinos are currently estimated to remain in the world, making this critically endangered rhino species one of Earth’s most threatened large mammal species.
However, all three Rhinoceros subspecies are endangered; three rhino species—black, Javan, and Sumatran—are critically endangered. Today, a small population of Javan rhinos is found in only one national park on the northern tip of the Indonesian island of Java. A mainland subspecies of the Javan rhino was declared extinct in Vietnam in 2011.

#6 Orangutans
About Orangutans
| Lifespan: Bornean orangutan: 35 – 45 years |
| Scientific name: Pongo |
| Gestation period: Bornean orangutan: 259 days |
| Mass: Sumatran orangutan: 45 kg, Bornean orangutan: 50 – 100 kg |
| Height: Sumatran orangutan: 1,4 – 1,8 m, Bornean orangutan: 1,2 – 1,4 m |
| Length: Sumatran orangutan: 83 cm, Bornean orangutan: 1,2 – 1,4 m |
Both species have experienced sharp population declines. A century ago, there were probably more than 230,000 orangutans in total. Still, the Bornean orangutan is estimated at 104,700 based on the updated geographic range (Endangered), and the Sumatran at about 7,500 (Critically Endangered).
The destruction and degradation of the tropical rain forest, mainly lowland forest, in Borneo and Sumatra is the main reason orangutans are threatened with extinction.
Palm oil, an ingredient found in many everyday food and cosmetic products, contributes to Sumatra’s rapid deforestation. Orangutan habitat in Sumatra and Borneo is being cleared at an alarming rate for conversion to oil palm plantations.

#7 Leatherback Sea Turtles
About Leatherback Sea Turtles
| Conservation status: Vulnerable (Population decreasing) |
| Scientific name: Dermochelys coriacea |
| Mass: 250 – 700 kg (Adult) |
| Clutch size: 110 |
| Length: 1,8 – 2,2 m (Adult) |
| Speed: 35 km/h (Maximum, In The Water, Swimming) |
Leatherback turtles are named for their shell, which is leather-like rather than hard, like other turtles. They are the largest sea turtle species and one of the most migratory, crossing the Atlantic and Pacific Oceans.
Leatherbacks occur in the Atlantic, Pacific, and Indian Oceans. They occupy U.S. waters in the West Pacific, East Pacific, and Northwest Atlantic. Pacific leatherback turtle nesting grounds are located in tropical latitudes in the eastern and western Pacific.
Extensive egg collection and bycatch in fishing gear are the primary causes of these declines. NOAA Fisheries designated all leatherback turtle populations as endangered under the Endangered Species Act in 1970.

#9 Irrawaddy Dolphins
About Irrawaddy Dolphins
| Conservation status: Vulnerable (Population decreasing) |
| Scientific name: Orcaella brevirostris |
| Trophic level: Carnivorous |
| Mass: 190 kg (Adult) |
| Length: 1,5 – 2,8 m (Adult) |
| Gestation period: 14 months |
The Irrawaddy dolphin is a euryhaline species of oceanic dolphin, meaning they transition between saltwater and freshwater. They lack most dolphins’ characteristic beaks and streamlined heads, instead having a blunt snout and a high, rounded forehead.
The Mekong River Irrawaddy dolphins inhabit a 118-mile stretch between Cambodia and Lao PDR and are scarce—just 92 individuals are estimated to exist still.
The dolphins are an essential indicator of the health and sound management of freshwater resources, and their decline could signal a potentially devastating decline in the health of the entire river ecosystem.
Where to see them responsibly?
The dolphins continue to die off at an alarming rate, and experts now estimate that only around 80 Irrawaddy dolphins are left in the Mekong between Kratie and the Lao border. The best place to see them is at Kampi, about 15km north of Kratie, on the road to Sambor ( Southeast Asia).

#10 Atlantic Bluefin Tuna
About Atlantic Bluefin Tuna
| Mass: 220 – 250 kg |
| Conservation status: Endangered (Population decreasing) |
| Scientific name: Thunnus thynnus |
Bluefin tuna populations have declined severely from overfishing and illegal fishing over the past few decades –not just Atlantic bluefin tuna, but Pacific bluefin tuna and Southern bluefin tuna. The demand for this fish in high-end sushi markets has primarily driven population declines.
The critically endangered bluefin tuna only makes up 1% of the global catch. As the methods of catching tuna have advanced over the years, the conservation and management of tuna have not evolved as quickly.
Scientists believe that the collapse of bluefin tuna in the Mediterranean Sea may lead to a sharp increase in the biomass of benthopelagic cephalopods, such as squid. This would negatively affect the sardine population.
Where to see them responsibly?
Bluefin tuna live mainly in the North Atlantic pelagic ecosystem and its adjacent seas, especially in the Mediterranean Sea. Geographically, their population is distributed throughout the North Atlantic, from Ecuador to Norway and from the Black Sea to Mexico.
Atlantic Bluefin Tuna Conservation
Center for Biological Diversity
Prized as a high-value dish at sushi restaurants, bluefin are being pushed toward extinction by decades of overfishing. The International Union for Conservation of Nature lists two species of bluefin, the Atlantic and the southern, as endangered or critically endangered, on its “Red List” of imperiled species.
How can we help: Eco Tourism for endangered animals
The goal of wildlife conservation is to ensure the survival of these species, and to educate people on living sustainably with other species.
Developing protective areas such as national parks, wildlife sanctuaries to protect the animals in their natural habitat. The endangered and vulnerable species can be kept in captivity in places such as local sanctuaries and bred to increase their population. The cutting of forests should be strictly prohibited.
The Foundations of Eco-Tourism
: tourism directed towards exotic, often threatened, natural environments to support conservation efforts and observe wildlife.
To successfully embody ecotourism, businesses must consider the following three measures: Sustainable Business Practices, Community Development, and Environmental Stewardship.
Our responsibility to wildlife
According to the International Union for Conservation of Nature, habitat destruction is the main threat to 85 percent of all threatened and endangered species.
You can help reduce this threat by planting native trees, restoring wetlands or cleaning up beaches in your area.
These are simple but sufficient methods to practice to maintain or pace the extent of human influence on the natural world.
Summary of the 10 Most Endangered Animals
As part of the world’s ecosystems, wildlife provides balance and stability to nature’s processes. The goal of wildlife conservation is to ensure the survival of these species, and to educate people on living sustainably with other species.
