How many animals are there which less in number?

There are many animal populations that are considered to be "less in number" or threatened with extinction. According to the International Union for Conservation of Nature (IUCN), there are currently 31,600 species listed as threatened, which represents 27% of all assessed species. Some examples of animals that have smaller population sizes include:

1. Amur Leopard: The Amur leopard (Panthera pardus orientalis) is a critically endangered subspecies of leopard found only in the remote forests of the Russian Far East and northeast China. There are estimated to be only around 100 individuals remaining in the wild.

2. Mountain Gorilla: The mountain gorilla (Gorilla beringei beringei) is a critically endangered subspecies of gorilla found only in the Virunga Mountains of central Africa. There are approximately 1,063 individuals remaining, divided into two populations.

3. Sumatran Rhino: The Sumatran rhinoceros (Dicerorhinus sumatrensis) is critically endangered and found only on the islands of Sumatra and Borneo in Southeast Asia. There are estimated to be only 80 individuals remaining in the wild.

4. Javan Rhino: The Javan rhino (Rhinoceros sondaicus) is critically endangered and native to the islands of Java and Sumatra in Indonesia. The population is estimated to be around 67 individuals, making it one of the rarest large mammals in the world.

5. Giant Panda: The giant panda (Ailuropoda melanoleuca) is endangered and endemic to the mountains of central China. The population is estimated to be around 1,864 individuals, with the majority living in the provinces of Sichuan, Shaanxi, and Gansu.

These are just a few examples of animals with dwindling populations. Conservation efforts are crucial to protect these species from further decline and ensure their survival in the wild.
