10 of the world's most endangered animals

We take a look at some of the most endangered animals in the world, and recommend where you can see them in their natural habitat.

1. Javan rhinoceros

Once the most widespread of Asian rhinos, Javan rhinos are now listed as critically endangered. With only one known population in the wild, it is one of the world's rarest large mammals. There are between 58 and 68 in the wild, with none living in captivity. The rhinos are often poached for their horns, although loss of habitat, especially resulting from the Vietnam War, has also contributed to their decline.

The only population of Javan rhinos can be found in Ujung Kulon National Park on the south-western tip of Java, Indonesia. The only other population in Vietnam, was wiped out in 2010.

2. Vaquita

With just 30 individuals left in the world, and only inhabiting one place, the vaquita is considered the most endangered marine mammal in the world. Thought to be threatened by fishing nets, the future looks bleak for this small porpoise. Chlorinated pesticides, irrigation and inbreeding also threaten the species.

Found solely in the northern part of the Gulf of California, Mexico, they are easily spotted due to the shallow water that they inhabit; lagoons generally no deeper than 30m. 

3. Mountain gorillas

Today, around 1000 mountain gorillas are thought to exist in the wild. The future is looking brighter for the primates; the gorilla population has almost doubled since 1981, when gorillas were thought to be on their way to extinction. Thanks to intensive conservation efforts, mountain gorillas were moved from 'critically endangered' to 'endangered' on the IUCN red list in 2018.

However, illegal poaching, pollution, habitat deforestation, fragmentation and diseases caught from humans are still threatening their populations. They are often poached for their meat, and younger gorillas can be caught in snares meant for other animals. War and civil unrest have also impacted negatively on the gorillas.

There are two mountain gorilla populations, which travellers can visit. One group can be found in the Virunga volcanic mountains of Central Africa across three national parks: Uganda's Mgahinga National Park, Rwanda's Volcanoes National Park and DR Congo's Virunga National Park (although this has been closed to tourists due to a recent violent rebellion). The other population inhabits Uganda's Bwindi Impenetrable National Park. You're most likely to see the gorillas in Rwanda or Uganda; you're unlikely to return disappointed.

4. Tigers

At the beginning of the 20th century, there were 100,000 tigers in the world. Today, this number is estimated to have dwindled to less than around 4,000 in the wild. Tigers need large areas of habitat, but living in some of the most densely populated places on Earth has placed them in locations that have caused significant conflict with humans. Habitat destruction and fragmentation has had the most significant effects on the tigers' habitats, and poaching is one of their biggest threats.

India is the best country to see tigers in the wild, but you can also spot tigers in Bangladesh, China, Sumatra, Siberia and Nepal. Check out some of the best places to see them.

5. Snow leopards

The wild snow leopard population is estimated to be between 4,080 to 6,590. They're found in 12 countries in Central Asia; inhabiting China, Bhutan, Nepal, India, Pakistan, Afghanistan, Tajikistan, Uzbekistan, Kyrgyzstan, Kazakhstan, Russia, and Mongolia. The species is threatened by herders who kill snow leopards to prevent them from preying on their livestock. Poachers, and a significant decrease in the leopards' wild prey are also an issue.

Snow leopards can be spotted in Mongolia's Gobi Gurvansaikhan National Park, the Himalayan mountains of Bhutan's Jigme Dorji National Park and Phoksundo Lake between Upper and Lower Dolpo in western Nepal's Shey-Phoksundo National Park. The leopards also descend from the high valleys of Ladakh in February, in India's Hemis National Park, in search of prey.

Once widespread, the orang utan has been considered critically endangered since 2000, and is one of the world's most endangered primates. A century ago, more than 230,000 orang utans lived in our world, but their numbers have now dropped by around half. Logging, forest fires, fragmentation, and especially the removal of tropical forests for palm oil, all critically threaten the orang utan's survival. Hunting and illegal pet trade have also dwindled numbers.

There are three types of orang utan to spot - the Bornean (over 100,000 in the wild), Sumatran (around 14,000 in the wild), and newly-discovered Tapanuli orang utan (only around 800 in the wild). Bornean orang utans can be spotted in both Malaysian and Indonesian Borneo, while Sumatran and Tapanuli orang utans can be spotted on the Indonesian island of Sumatra.

8. Leatherback sea turtles

In between 26,000 and 43,000 female sea turtles nest annually; a dramatic decline from the estimated 115,000 in 1980. Young turtles are incredibly vulnerable and sadly, very few make it to adulthood. Birds and small mammals often dig up turtle nests in order to eat the eggs. Once they've hatched, birds and crustaceans pick them off before they can make it to the sea, and fish, squid and octopuses often prey on them if they do manage to make it into the water.

The prime nesting spots for the turtles are in Suriname, French Guiana, Grand Anse beach in St Lucia, Turtle Beach in Tobago, Guyana's Shell Beach and Gabon. The Mayumba National Park beaches in Gabon host the largest nesting population on the African continent. April is the time to visit, when around 30,000 turtles descend on the park's beaches to lay their eggs.

9. Asian elephants

Asian elephants have been considered an endangered species since 1986, and their population has decreased by at least 50% over the last 75 years or so, with fewer than 50,000 remaining in the wild. Fragmentation, deforestation and an increasing human population are destroying the elephants' habitat and decreasing the space available for them to live in.

The Sri Lankan, Indian and Sumatran Asian elephants can of course be found in their countries of name and other mainland Asian countries. However, the best opportunity to see Asian elephants is at The Gathering, a natural assembly of up to 300 elephants coming to the shores of the Minneriya Tank in Sri Lanka's Minneriya National Park during August to bathe and drink. It is the largest congregation of Asian elephants in the world.

10. Atlantic bluefin tuna

Bluefin tuna numbers have declined at a staggering rate over the last 40 years; records show a 72% decrease in the Eastern Atlantic and an 82% decrease in the West. Overfishing is the main cause for the destruction of this species due to their commercial value as food. They have been heavily targeted for the Japanese fish market, where they are highly sought-after for sushi and sashimi. However, farming is the most serious threat to the species, as the tuna are taken from the wild before they are old enough to reproduce.

Native to the western and eastern Atlantic Ocean and the Mediterranean Sea, the tuna are very hard to track, and can be found off the coasts of many countries; from Brazil to Norway. However, they are known to return to spawn every year in the Mediterranean sea and the Gulf of Mexico.
