Transcript of "Extinct or Not?"

  1. 1. Extinct or Not? • Golden Toad
  2. 2. Extinct • 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.
  3. 3. Extinct or Not? • Chinese River Dolphin
  4. 4. Extinct • Qi Qi, a rare Chinese river dolphin, was rescued from the Yangtze River in 1980 and lived in Wuhan Baiji Aquarium, until she died in 2002. A recent six-week search on the Yangtze failed to find any trace of the endangered dolphin species, leading scientists to announce that the animal is "functionally extinct."
  5. 5. Extinct or Not? • Koala bears
  6. 6. Not • Extreme drought, ferocious bushfires and urban development could make koalas extinct within seven years, environmentalists are warning.
  7. 7. Extinct or Not? • Dodo
  8. 8. Extinct • The Dodo is the most famous extinct species in the history of Planet Earth. Its first contact with Europeans was in 1598, when a Dutch expedition headed by Admiral Jacob Cornelius van Neck landed on an island, thick with dense forests of bamboo and ebony, off the East coast of Africa. The island was named Mauritius by the adventurous and artistic Admiral – the first man to draw the extraordinary and unique flightless bird, now universally known as the Dodo (from the Dutch word 'dodoor' meaning sluggard). The demise of the Dodo has been attributed to hungry Dutch sailors en route to the Spice Islands of Indonesia. They would take a dinner break on the tropical island and consume the defenseless Dodo.
  9. 9. Extinct or Not? • Burmese star tortoise
  10. 10. Not • Three critically endangered Burmese star tortoises are pictured May 22, 2008 at the San Diego Zoo, the first time this species has successfully reproduced at the facility. The Burmese star tortoise is not often bred in zoos, but with more as-yet-unhatched eggs, animal care staff is hoping that more of the tortoises emerge. The reptile is almost extinct in its native Myanmar as its numbers dwindle due to deforestation and hunting, both for food and profit.
  11. 11. Extinct or Not? • Quagga
  12. 12. Extinct • One of Africa's most famous extinct animals, the quagga was a subspecies of the plains zebra, which was once found in great numbers in South Africa's Cape Province and the southern part of the Orange Free State. It was distinguished from other zebras by having the usual vivid marks on the front part of the body only. In the midsection, the stripes faded and the dark, inter-stripe spaces became wider, and the hindquarters were a plain brown. The name comes from a Khoikhoi word for zebra and is onomatopoeic, being said to resemble the quagga's call.
  13. 13. Extinct or Not? Snow Leopard
  14. 14. Not • Found above the tree line and near permanent snow in central Asia's dry mountainous country, the snow leopard has been prized as a hunter's trophy, destroyed as a predator of domestic flocks, and sought as a source of valuable fur. Complete information as to its numbers is not available, but almost everywhere it is considered to be rare or in decline. Currently, the most serious threat to its survival is loss of habitat due to human expansion.
