Top 50 Endangered Species of the World and Where to Find Them

An endangered species is referred as a species of animal or plant that is seriously at risk of extinction if something is not done to keep them from disappearing forever.

The International Union for the Conservation of Nature (IUCN) lists species that are threatened, endangered, critically endangered and vulnerable.

Talking about the endangered species, as of 2012, IUCN has listen 3,079 animals as endangered throughout the world.

The surviving number of these species should be of utmost concern for us.

Keeping in mind the need of stringent steps to be taken for the conservation of these species, this article is providing a list of top 50 endangered species in the world and where to find them.

1.Javan Rhino:

Once, they were found throughout the northeast India and Southeast Asia. But the frequent poaching has resulted to their decline.

They’re the most threatened among the five species of rhinoceros; with only 58-68 population remaining that live only in Ujung Kulon National Park in Java, Indonesia.


Vaquita, the world’s rarest mammal is on the verge of extinction with only 10 individuals remaining in the world.

Use of chlorinated pesticides, irrigation, fishing nets and inbreeding has led to their population decline.

They’re solely found in the northern part of the Gulf of California, Mexico.

3.Amur Leopard:

The Amur leopard is the most critically endangered species among all the species of leopards.

Hunting for their thick fur is the major reason for their declination.

The last viable population is around 84 individuals only, found in Amur Heilong, which covers area of Northeastern china and Russian Far east.

4.Mountain Gorilla:

Conservative efforts led them move from critically endangered to endangered species on the IUCN red list.
