& Extinct


By: Marianne Trejos & Sofia Debbiche

Science Department









About the Puma:

Where pumas are eliminated, populations of prey animals (such as deer) get too big for the land to accommodate. As prey numbers increase, vegetation is soon overgrazed. As adequate food supplies diminish, deer and other prey animals starve at massive levels. At the human level, animals that were once eaten by pumas and other predators destroy crops. If the world were to lose the puma it would have impacts all over the world.

Approximate population:

Worldwide: 30,000

Protective Measures:

- To create land reserves for them to live on.

- Create laws for the prevention of hunting

  • Common Name: Puma
  • Scientific Name: felisconcolor
  • Habitat: Pumas live in a variety of habitats; ranging from North to South America. In Costa Rica they live in the tropical Rain Forest
  • Threats: Throughout the world, pumas are endangered species. They have been hunted for their furs for centuries. They also compete for the same food sources as humans do.

About Geoffroy’s Spider Monkey

Threats: They are hunted by humans, habitat loss, and are captured for trade. They also have slow reproductive systems.

Measures to protect it:

- create nature reserves

- reestablish habitat

habitat preservation

Approximate Population: There is no exact number, but the population decreases each year.

  • Common Name: Geoffroy’s Spider Monkey
  • Scientific Name: atelesgeoffroyi
  • Habitat: Spider monkeys are found on the coasts of lowland rain- and mountain forests. They are mostly found in Panama, Costa Rica & Nicaragua.

Snow Leopard

About Snow Leopard

Threats: the illegal trading and revenge killing by livestock owners. They are traded for their pelts, bones and body parts. Lately there has been an increase in leopard bones as a substitute for tiger bones in traditional Chinese medicine as illegal trade of tiger parts has been more strictly enforced. There is also loss of habitat, and a decrease un food supply.

Measures to protect:

To refuse to buy any product derived from Snow Leopards

To encourage others not to buy traditional Chinese medicine made from Snow Leopard bones or other body parts

To donate money to organizations helping snow leopard

Approximate population: there are approximately from 4,00 to 7,000 snow leopards in the wild, and 600-700 in zoos

  • Common Name: Snow Leopard
  • Scientific Name: PantheraUncia
  • Habitat: the Snow Leopard lives in rocky mountain sides, shrub lands, grasslands and alpine plateaus at altitudes of about 9,000 to 12,000 feet. Today they are only found in the countries of Afghanistan, Bhutan, China, India, Kazakhstan, Kyrgyzstan, Mongolia, Nepal, Pakistan, Russia, Tajikistan and Uzbekistan.

  • Name: Baiji’s Dolphin
  • Scientific Name: lipotesvexilliter
  • Last Sighting: 2002. It is said that in 2006 there was a sighting of one of these dolphin.
  • Habitat: this dolphin used to live in fresh water only, and was commonly found in the Yangtze River, in China.
