How far can the human go just for avarice? Well here is a list of some species that have been victims of human cruelty, I guess the animals I expose here aren't the only ones that have been extinct in the last 150 years. The description of each animal can be of other sources not specified (no space).

Thylacine (extinct: 1936)




The Thylacine was the largest known carnivorous marsupial of modern times. Native to Australia and New Guinea, it is thought to have become extinct in the 20th century. It is commonly known as the Tasmanian Tiger (due to its striped back), and also known as the Tasmanian Wolf, and colloquially the Tassie (or Tazzy) Tiger or simply the Tiger. It was the last extant member of its genus, Thylacinus, although a number of related species have been found in the fossil record dating back to the early Miocene.

The Thylacine became extinct on the Australian mainland thousands of years before European settlement of the continent, but survived on the island of Tasmania along with a number of other endemic species such as the Tasmanian Devil. Intensive hunting encouraged by bounties is generally blamed for its extinction, but other contributory factors may have been disease, the introduction of dogs, and human encroachment into its habitat. Despite being officially classified as extinct, sightings are still reported.

Quagga (extinct: 1880)




A yellowish-brown subspecies of the plains zebra with stripes only on its head, the quagga was a close relative of horses and zebras. It lived on grassy plains and in the drier parts of South Africa.
The name comes from a Khoikhoi word for zebra and is onomatopoeic, being said to resemble the quagga's call. The only quagga to have been photographed alive was a mare at the Zoological Society of London's Zoo in Regent's Park in 1870.
It is very sad to know that the true quagga was hunted down for meat and vanished almost unnoticed, before any conservation efforts were made.

Passenger Pigeon (extinct: 1914)




Probably the most terrible example of mass slaughter in the history of wildlife was not the bison but the passenger pigeon.

The Passenger Pigeon, once probably the most numerous bird on the planet, made its home in the billion or so acres of primary forest that once covered North America east of the Rocky Mountains. Their flocks, a mile wide and up to 300 miles long, were so dense that they darkened the sky for hours and days as the flock passed overhead. Population estimates from the 19th century ranged from 1 billion to close to 4 billion individuals. Total populations may have reached 5 billion individuals and comprised up to 40% of the total number of birds in North America (Schorger 1995). This may be the only species for which the exact time of extinction is known.

The Passenger Pigeon was similar to but larger than the Mourning Dove. It had a slate blue head and rump, slate gray back, and a wine red breast. The colors of the male were brighter than those of the female.

Bubal Hartebeest (extinct: 1923)




There is evidence that the hartebeest once was domesticated by the ancient Egyptians and used as a sacrificial animal (Kingdon 1990 and African Wildlife Foundation). Its horns in Egyptian tombs at Abadiyeh indicate its importance mythologically as well as a food source. (Day 1981) It was mentioned by Aristotle, Æschylus and Pliny. It is also mentioned in the Old Testament under the name 'Yachmur', incorrectly translated as 'fallow deer'. (Edwards 1996)

Hartebeest were formerly common in Morocco, but numbers were severely reduced by hunting during the 19th century. Since then "the Bubal has retired far beyond the Atlas into the recesses of the desert, and has become a difficult animal to meet with" (Sclater and Thomas 1894). The last known specimens in Morocco were shot in 1925 in the upper Moulouya Valley, Eastern Morocco (Loggers et al. 1992), but few authorities credited the claim (Day 1981).

The captive female which died in Jardin des Plantes in Paris, France, on 9 November 1923 is usually held to have been the last of its kind.

Round Island Burrowing Boa (extinct: 1975)




The Round Island Burrowing Boa reached a length of about 1 m (39 in). Preserved specimens have reported total lengths of 54-140 cm. Vinson (1949) even claimed that its maximum size was 1,8 m. The colour in life has been described as light brown with small blackish spots dorsally and pink marbled with blackish ventrally. It was characterized by a pointed snout and by a cylinder-shaped body and head.

The best-known species of Round Island, Mauritius, the burrowing boa was last seen in August 1975. One of two members of a unique sub-family of primitive boas, it preferred to live in the topsoil of volcanic slopes. It is believed that extreme habitat changes and the use of poisons for the extermination of rabbits may have driven this predator to extinction.

Javan Tiger (extinct: 1979)




Javan tigers were known for their unusually long cheek whiskers. They once roamed on the Indonesian Island of Java and were considered pests by island natives. Agricultural development led to a severe decline in their population. The last evidence of the tigers' existence was in 1979. Since then, sadly no one has ever seen them again.

In the early 19th century Javan tigers (Panthera tigris sondaica) were so common over Java that in some areas the were considered nothing more than pests.

They were driven to the verge of extinction through a rapid increase in human population leading inevitably to a severe reduction in habitat. Forests were felled then converted for agricultural use. Along with this tigers were merciless hunted and poisoned, and they experienced growing competition for prey species with wild dogs and leopards.
Much of the hunting was carried out by natives, a surprising thing since they considered the tiger a reincarnation of their dead relatives.

Baiji (Possibily extinct: 2006)




Was a freshwater dolphin found only in the Yangtze River in China. Nicknamed "Goddess of the Yangtze" is also called Chinese River Dolphin, Yangtze River Dolphin, Whitefin Dolphin and Yangtze Dolphin. It is not to be confused with the Chinese White Dolphin.

The Baiji population declined drastically in decades as China industrialized and made heavy use of the river for fishing, transportation, and hydroelectricity. Efforts were made to conserve the species, but a late 2006 expedition failed to find any Baiji in the river. Organizers declared the Baiji "functionally extinct"

In August 2007, a Chinese man reportedly videotaped a large white animal swimming in the Yangtze. Although Wang Kexiong of the Institute of Hydrobiology of the Chinese Academy of Sciences has tentatively confirmed that the animal on the video is probably a Baiji, the presence of only one or a few animals, particularly of advanced age, is not enough to save a functionally extinct species from true extinction. The last known living Baiji was Qi Qi , which died in 2002.

Japanese Sea Lion (Extinct: 1970's)




The Japanese sea lion (Zalophus japonicus) is thought to have become extinct in the 1970s.

Harvest records from Japanese commercial fishermen in the early 1900s show that as many as 3,200 sea lions were harvested at the turn of the century and overfishing caused harvest numbers to fall drastically to 300 sea lions by 1915 and to few dozen sea lions by the 1930s. Japanese commercial harvest of Japanese sea lions ended in the 1940s when the species became virtually extinct. In total, Japanese trawlers harvested as many as 16,500 sea lions, enough to cause their extinction. It is even believed that submarine warfare during World War II contributed to their habitat destruction. The most recent sightings of Zalophus japonicus are from the 1970's with the last confirmed record being a juvenile specimen captured in 1974 off the coast of Rebun Island, northern Hokkaido.

Caribbean Monk Seal (Extinct: 1952)




Caribbean monk seals had a fairly large, long, robust body, and could grow up to about 8 ft (2.4 m) in length and weighed 375-600 lbs (170-270 kg). Males were probably slightly larger than females, which is similar to Mediterranean monk seals.

Monk seals became easy targets for hunters while resting, birthing, or nursing their pups on the beach. Overhunting by humans led to these seals’ demise, according to NOAA biologists.

The last confirmed sighting of the seal was in 1952 in the Caribbean Sea at Seranilla Bank, between Jamaica and the Yucatán Peninsula. This was the only subtropical seal native to the Caribbean Sea and Gulf of Mexico.


Tecopa Pupfish (extinct: 1982)




Native to the Mojave Desert, California, the Tecopa pupfish was first described in 1948. Found only in the North and South Tacopa, two springs of the Amaragosa River system, the fish was added to the endangered species list in 1970. It was later declared extinct, in 1982, after its natural habitat was destroyed by developers.


The Golden Toad (extinct: 1989)




The extinct Golden Toad (Bufo periglenes) was a small, shiny, bright-orange toad that was once abundant in a small region of high-altitude cloud-covered tropical forests, about 30 square kilometers in area, above the city of Monteverde, Costa Rica. For this reason, it is sometimes also called the Monteverde Golden Toad, or the Monte Verde Toad.

The Golden Toad was described in 1966 by the herpetologist Jay Savage. Since 1989, not a single Golden Toad has been seen anywhere in the world, and it is classified by the IUCN as an extinct species.


Zanzibar Leopard (extinct: 1996)




Found only in the Zanzibar archipelago of Tanzania, this unique subspecies of leopard may have gone extinct as recently as the 1990s.

Due to the widespread but ridiculous belief among locals that these cats are kept by witches and sent by them to cause harm, an extermination campaign was launched and has been underway for decades.

Though reports still occasionally surface of sightings of Zanzibar leopards, none have been confirmed since the 1980s and most zoologists presume the extermination campaigns have succeeded.

Extermination by humans and deforestation were largely responsible for their disappearance in the 20th century.


Pyrenean Ibex (extinct: 2000)




In 1980, about 30 Pyrenean ibex were reported to exist. With the death of their last family member in 2000, they were declared extinct.

The last natural Pyrenean Ibex, a female named Celia, was found dead on January 6, 2000, killed by a falling tree. Although her cause of death is known, the reason for the extinction of the subspecies as a whole is a mystery. Some hypotheses include the inability to compete with other species for food, infections and diseases, and poaching. The Pyrenean Ibex became the first taxon ever to become "un-extinct", for a period of seven minutes in January 2009, when a cloned female Ibex was born alive and survived a short time, before dying from lung defects


Po'o-uli (extinct: 2004)




The Poʻouli was not discovered until 1973 by students from the University of Hawaiʻi, who found the bird on the north-eastern slopes of Haleakala on the island of Maui. It was found during the Hana Rainforest Project at an altitude of 1,980 metres (6,500 ft) above sea level. The Poʻouli was the first species of Hawaiian Honeycreeper to be discovered since 1923.

Predators, a decline in food sources, and habitat loss are all thought to have been responsible for the beautiful bird‘s demise. By 1997, only three individuals were known to exist. Later, in 2004, the last known male bird also died in captivity.


Spix's Macaw (Wild extinct: 2004)




The spix’s macaw, the world’s rarest parrot, disappeared from the wild recently. Also known as the little blue macaws, it was the only member of the parrot genus Cyanopsitta. This magnificent bird, which came in various shades of blue, was endemic to the state of Bahia, Brazil and the Caraibeira Riparian Woodland. Though some of them are still participating in captivity breeding program, they have been declared extinct in the wild.



Madeiran Large White (extinct: 2007)




Once upon a time, this magnificent white butterfly flew in the humid subtropical forests of Portugal's Madeira Islands. The gorgeous butterfly had a very limited distribution, as they lived in a very rare type of forest. Researchers believe that pollution from agricultural fertilizers and deforestation could be the reasons for their extinction.

We humans are destroying the concept of the food chain. Every day, a few plants and animals go extinct. The time has come to think things over again.

Mariana Mallard (Extinct: 1981)




The Mariana Mallard is an extinct species of mallard that lived only on the Mariana Islands. The Mariana Mallard is classed as part of the Anas genus however its taxodermic status is open to debate.

Over the years debates have ranged about the Mariana Mallard with some claiming the Mariana Mallard as a subspecies of the Indian spot-billed duck, some favoring the Mariana Mallard to be a subspecies of the Pacific black duck while others believe it to be a stand alone species.

Mariana Mallard’s weighed in at around 1 kilograms and grew to around 55cm in length making them slightly smaller than common mallards. As is the case with male mallards, the male Mariana Mallard had a green head that was not as bright as today’s mallard.

Gastric-brooding frog (Extinct: 1980)




The gastric-brooding frogs or Platypus frogs (Rheobatrachus) were a genus of ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, both of which became extinct in the mid-1980s. The genus was unique because it contained the only two known frog species that incubated the prejuvenile stages of their offspring in the stomach of the mother.

The cause for the gastric-brooding frogs' extinction is unknown but habitat loss/degradation, pollution, pathogens, parasites and over collecting may have contributed. Populations of Southern Gastric-brooding Frogs were present in logged catchments between 1972 and 1979. The effects of such logging activities upon Southern Gastric-brooding Frogs was not investigated but the species did continue to inhabit streams in the logged catchments. The habitat that the Southern Gastric-brooding Frog once inhabited is now threatened by feral pigs, the invasion of weeds, altered flow and water quality problems caused by upstream disturbances. Despite intensive searching, the species has not been located since 1979 or 1981.


Lesser Bilby (Extinct: 1950)




The Lesser Bilby (Macrotis leucura), also known as the Yallara, the Lesser Rabbit-eared Bandicoot or the White-tailed Rabbit-eared Bandicoot, was a rabbit-like marsupial. The species was first described by Oldfield Thomas as "Peregale leucura" in 1887 from a single specimen from a collection of mammals of the British Museum.

Since its discovery in 1887, the species was rarely seen or collected and remained relatively unknown to science. In 1931 Finlayson encountered many of them near Cooncherie Station, collecting 12 live specimens. Although according to Finlayson this animal was abundant in that area, these were the last Lesser Bilbies to be collected alive.

The last specimen ever found was a skull picked up below a Wedge-tailed Eagle's nest in 1967 at Steele Gap in the Simpson Desert, North West Territorry. The bones were estimated at being under 15 years old.


Canarian Oystercatcher (Extinct: 1940)




This bird was last collected in 1913, and local fishermen and lighthouse keepers reported it had disappeared around 1940 (Hockey 1996), after a prolonged decline starting probably in the 19th century (Hockey 1987). It first - until the early 20th century - seems to have disappeared from Lanzarote, in accord with the general pattern of Canarian extinctions. By 1913, it was not reported to have been found outside the Chinijo Archipelago and Islote de Lobos in recent times.

It is now considered extinct, because extensive surveys between 1956/57 and the late 1980s failed to find any evidence of the Canarian Black Oystercatcher's survival. It was officially declared extinct with publication of the 1994 IUCN Red List.

Glaucous Macaw (Extinct: 1938)




This macaw is critically endangered or possibly extinct. It is closely related to the Lear's Macaw A. leari and the Hyacinth Macaw A. hyacinthinus. In Guaraní, it was called guaa-obi after its vocalizations.

The Glaucous Macaw is 70 centimetres (28 in) long. It is mostly pale turquoise-blue with a large greyish head. The term glaucous describes its colouration. It has a long tail and a large bill. It has a yellow, bare eye-ring and half-moon-shaped lappets bordering the mandible.

Laughing Owl (Extinct: 1918)




Also known as Whēkau or the White-faced Owl, was an endemic owl found in New Zealand, but is now extinct. It was plentiful when European settlers arrived in New Zealand in 1840. Specimens were sent to the British Museum, where a scientific description was published in 1845. The species belongs to the monotypic genus Sceloglaux ("scoundrel owl", probably because of the mischievous-sounding calls).

By 1880, the species was becoming rare, and the last recorded specimen was found dead at Bluecliffs Station in Canterbury, New Zealand on July 5, 1914 (Worthy, 1997). There have been unconfirmed reports since then; the last (unconfirmed) North Island records were in 1925 and 1927, at the Wairaumoana branch of Lake Waikaremoana.

Bali tiger (Extinct: 1937, confirmed: 2011)




The Bali Tiger (Panthera tigris balica), harimau Bali in Indonesian, or referred to as samong in archaic Balinese language, was a subspecies of Tiger which was found solely on the small Indonesian island of Bali. This was one of three sub-species of tiger found in Indonesia, together with the Javan Tiger, which is also extinct, and the critically endangered Sumatran Tiger. It was the smallest of the Tiger subspecies.

The last specimen definitely recorded was a female shot at Sumbar Kima, west Bali, on September 27, 1937. However it is thought likely a few animals survived into the 1940s and possibly 1950s. The sub-species became extinct because of habitat loss and hunting. Given the small size of the island, and limited forest cover, the original population could never have been large.
