Their diet included leafy plants and shoots. In the 1930s preservation action was taken to protect the species, but the numbers continued to decline.

  2. Baiji White Dolphin: also called the Chinese River Dolphin, can only be found in the Yangtze River in China. These mammals could grow to eight feet long and weigh up to a quarter of a ton. They relied on echolocation to navigate and hunt for prey due to their tiny eyes and very poor eyesight. Although not officially recorded as extinct, no one has seen a Yangtze River Dolphin since 2002.
  3. Pyrenean Ibex: One of four subspecies of the Spanish Ibex or Iberian Goat that was found in the Iberian Peninsula. The Ibex would grow to a height of 60-76cm at the shoulder and weigh 24-80 kg and feed mainly on grasses and herbs. The last Pyrenean Ibex was killed by a falling tree in northern Spain in 2000.
  4. Great Auk: A large and flightless bird found in the North Atlantic and as far south as Northern Spain. It had an average height of 75-85 cm and weighed about 5kg. The last of these birds were killed by three men who caught it in St Kilda, Scotland in 1844. When a large storm surged, they believed that the auk was a witch and was causing the storm, so they killed it.
  5. Stellers Sea Cow: Named after George Steller, a naturalist who discovered the creature in 1741, Stellers Sea Cow was a large herbivorous mammal. the fact that it was unable to submerge its enormous body, is possibly what made it vulnerable to human hunters.
