The rarest animal in the world is the
Celia, the last Pyrenean ibex (Capra pyrenaica pyrenaica), was found dead on 6 January 2000 in the Spanish Pyrenees, after hunting and competition from livestock reduced the population to one individual.
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.
In terms of numbers of species, insects certainly represent the largest percentage of the world's organisms. There are more than 1 million species of insects that have been documented and studied by scientists.
Kangaroo. There are about 50 million kangaroos living in Australia, that means there are many more kangaroos than people living in Australia! There are 55 different species of kangaroos.
At least 680 vertebrate species had been driven to extinction since the 16th century and more than 9% of all domesticated breeds of mammals used for food and agriculture had become extinct by 2016, with at least 1,000 more breeds still threatened.
According to the WWF, there are approximately only 4,500 tigers left in the wild. However, some estimates put the number even lower. Habitat loss is a major factor in the decline in wild tiger populations.
The sheer scale of the disaster facing the planet shocked those involved in the research. They estimate that more than 1 million species will be lost by 2050.
1. Xoloitzcuintli (Mexican Hairless Dog) A dog breed that has been on this planet for over 3000 years, the Aztec dog of the gods, Xoloitzcuintli was almost extinct back in the 1950s but due to efforts by breeders, it has survived.
Humans and mice share nearly 90 percent of human DNA. This is important because mice have been used in laboratories as experimental animals for research into human disease processes for years.
Large mammals, such as primates, cattle, horses, some antelopes, giraffes, hippopotamuses, rhinoceroses, elephants, seals, whales, dolphins, and porpoises, generally are pregnant with one offspring at a time, although they may have twin or multiple births on occasion.
Wild animals such as pandas and elephants are likely to become extinct as soon as 2025. Could you imagine by the time you may have started a family it is a possibility that your children will never see a panda or elephant?
They conclude that while one on one, a tiger would certainly best a lion, in the wild the lion pride could hold their own against the solitary tiger.
In the past decade, over 55% tigers (478 tiger deaths) died inside tiger reserves, more than 31% (271) outside the reserves and over 12% (108) of poaching.
2) Tigers are carnivores, eating only meat.
They mainly feed on large mammals such as deer, wild pigs, antelope and buffalo.
The typical rate of extinction differs for different groups of organisms. Mammals, for instance, have an average species "lifespan" from origination to extinction of about 1 million years, although some species persist for as long as 10 million years. There are about 5,000 known mammalian species alive at present.
Approximately 300,000 years ago, the first Homo sapiens — anatomically modern humans — arose alongside our other hominid relatives.
