The extinction of an animal species occurs when the last individual member of that species dies. Although a species may be "extinct in the wild," the species is not extinct until every individual, regardless of location, captivity, or ability to breed, has died. Extinction of Animals Causes

There are several causes of extinction of several animal species, prominent among which are loss of habitat, extinction of animals due to deforestation, extinction of animals due to global warming, extinction of animals due to hunting.

List of Extinct Animals

The long list of extinct animals in the world features more than 50 animal species that have become extinct from the planet in last 100 years alone. This extinct animals list feature mammals, birds, reptiles as well as amphibians. Now let us have a detailed look at some of the prominent extinctions in last 100 years, and the causes behind these extinctions. May be going through the list will help us in realizing how we were, directly or indirectly, responsible for the tremendous loss our planet has undergone over the years.

Arabian Ostrich
Arabian ostrich, also known as the Middle Eastern ostrich, is a subspecies of ostrich native to the Arabian Peninsula. Arabian ostrich extinction was triggered by the widespread introduction of firearms, which made hunting a relatively easy task. By the beginning of 20th century, Arabian ostrich had become relatively rare, and by mid 20th century the bird had virtually vanished. The last sighting of this subspecies had been recorded in 1966, wherein a dying individual was found near Petra, Jordan.

Atitlan Grebe
The Atitlan Grebe, also known as the Giant Grebe or the Poc, was a water bird endemic to the Lago de Atitlán in Guatemala. A full-grown bird reached to the length of about 46-50 cm and resembled the Pied-billed Grebe to a great extent. Introduction of the Smallmouth bass and Largemouth bass species of fish in Lake Atitlan in 1950s and 1960s reduced the number of crabs and fish in the lake, thus depleting the source of food for the Atitlan Grebe. Though there was a slight recovery in 1970s, an earthquake, that hit Guatemala in 1976, fractured the lake bed and drained the water. This loss of habitat severely affected the Atitlan Grebe population and the bird was last seen in 1989.

Bali Tiger
The Bali tiger, native to a small island in Indonesia named Bali, is the smallest of the three subspecies of tigers found in Indonesia. The deforestation caused due to human encroachment was the major factor which affected the basic existence of the Bali tiger. The last documented sighting of a Bali tiger was in form of an adult female that was killed in West Bali in September 1937.

Barbary Lion
The Barbary lion, also known as the Atlas lion, was a subspecies of lion native to Northern regions of Africa. Weighing between 440 to 600 lbs, the Barbary lion was considered to be the heaviest among the lion subspecies. Excessive hunting led to the depletion of Barbary lion population in the wild. Loss of habitat due to the expansion of agricultural lands was also a prominent cause of Barbary lion extinction. Initially declared extinct, the animal was later given the special status - 'extinct in the wild' (EW) by the IUCN as a few individuals were found to be alive in captivity in zoos and circus.

Bubal Hartebeest
The Bubal Hartebeest was a subspecies of antelope that inhabited the African nations of Algeria, Egypt, Libya, Morocco and Tunisia. The animal was caught and domesticated by the Egyptians in order to perform sacrifices. By the beginning of the 20th century, the population of Bubal Hartebeest depleted to a large extent, and its habitat was only restricted to Algeria and Morocco. In Morocco, hunting by French further decreased the number of this species. During the same time many individuals were caught and kept in the zoos, where they eventually died. The last known Bubal Hartebeest was a female that died in a zoo in Paris...
