1. TOP 10 EXTINCT
ANIMALS
By: Giezzel Beltran

2. Splendid Poison
frog ( extinct 2020)
01

3. The splendid poison frog or poison-arrow frog was a
species of poison dart frog endemic to the end of western
Panama. Deforestation and habitat degradation are the
primary threats to the splendid poison frog. Human
activities such as logging, expansion of urban and
suburban areas, and the construction and use of rail
lines contributed significantly to the frog’s extinction.

4. Bramble Cay
melomys ( extinct
2019)
02

5. The Bramble Cay melomys, or Bramble Cay
mosaic-tailed rat, is a recently extinct species of
rodent native to the isolated Bramble Cay, a
vegetated coral cay located at the northern tip of
the Great Barrier Reef in Australia.

6. Scientists have determined that the Bramble cay
melomys, named after an island of the same
name went extinct due to human-driven climate
change. The melomnys’s 10-acre habitat, Bramble
Cay, sat less than 10 feet above sea level.

7. Baiji Dolphin
( Estimated extinct
2020)
03

8. The baiji is a possibly extinct species of freshwater dolphin,
and is thought to be the first dolphin species driven to
extinction due to the impact of humans. Since Baiji means
‘white fin’ in Chinese, it means ‘white-finned dolphin’.
The likely cause of the baiji’s decline is the use of fishing
nets with hooks that snag and drown the dolphins as
bycatch. Other causes may include habitat degradation.

9. Pinta Giant Tortoise
( Estimated extinct
2012)
04

10. The Pinta Island tortoise, also known as the
Pinta giant tortoise or Abingdon Island
tortoise, is a species of Galápagos tortoise
native to Ecuador’s Pinta Island that is most
likely extinct.

11. The Pinta Island tortoise, thought to have
gone extinct with the death of Lonesome George in
2012, is not extinct as scientists found
31 tortoises on Isabella Island in the Galapagos
Island chain that are believed to be partially
descended from the Pinta Island tortoise but are
functionally extinct in their natural environment.

12. Western Black Rhino
( Extinct 2011)
05

13. The western black rhinoceros or West African
black rhinoceros is an extinct subspecies of the
black rhinoceros. It was declared extinct by the
IUCN in 2011. But the western black rhino and
northern white rhinos have recently become
extinct in the wild.

14. The only two remaining northern white rhino are
kept under 24-hour guard in Ol Pejeta
Conservancy in Kenya. The main reason the West
African black rhino is extinct is because of
poachers or illegal hunters. Poachers killed them
solely for their horns, for use in Chinese medicine
and as decoration in the Middle East.

15. Alaotra grebe Bird
( Extinct 2010)
06

16. The Alaotra grebe, also known as Delacour’s little or
rusty grebe, is an extinct grebe endemic to
Lake Alaotra and its surrounding lakes in
Madagascar. The last known sighting of the bird
was in 1985 and experts have now confirmed its
demise, killed off by a combination of poaching and
predatory fish.

17. Spix’s Macaw
( Functionally
extinct 2000)
07

18. Spix’s macaw, also known as the little blue macaw,
is a macaw native to Brazil. The Spix’s macaw is
one of the rarest birds in the world: it is estimated
that there are only 177 captive individuals
worldwide. The species was declared extinct in the
wild in 2000.

19. Moorean viviparous
tree snail
( Functionally
extinct)
08

20. Partula mooreana, common name
the Moorean viviparous tree snail, is a species
of air-breathing tropical land snail, a terrestrial
pulmonate gastropod mollusk in the family
Partulidae. This species was endemic to French
Polynesia. It is now extinct in the wild.

21. Pyrenean ibex
( Extinct
2000/2009)
09

22. The Pyrenean ibex was a mountain goat that
was substantially bigger and had more
enormous horns than its extant cousins, C. p.
hispanica and C. p. victoriae. It was also called
the Pyrenean wild goat and, in Spain, the
bucardo.

23. While the exact cause of the Pyrenean ibex’s
extinction is unknown, scientists hypothesize
that some factors contributed to the species’
decline, including poaching, disease, and the
inability to compete with other domestic and
wild ungulates for food and habitat.

24. Asiatic Cheetah
(Functionally extinct
since 1948)
10

25. The Asiatic cheetah is a Critically
Endangered cheetah subspecies surviving
today only in Iran. It once occurred from
the Arabian Peninsula and the Near East to
Caspian regions. Less than 50 remain in the
wild, therefore functionally extinct.

26. Why are animals
important?

27. Animals improve the welfare of humans in many
ways, ranging from providing companionship,
improving mental health, facilitating rescues during
natural disasters; and finally, for a number of
species, as food. Dogs used in therapy, and as aids
for people with disabilities, provide important
benefits.
