Our planet has been home to countless remarkable species over millennia. Unfortunately, some of them have disappeared forever
Tasmanian Tiger (Thylacine)
The Tasmanian Tiger, or Thylacine, was a unique marsupial carnivore native to Australia and Tasmania. Despite its tiger-like stripes, it was a marsupial, not a big cat
Dodo Bird
The Dodo Bird, native to Mauritius, was famously flightless and trusting of humans. Its extinction in the 17th century serves as a stark reminder of the impact of human activity on wildlife.
Woolly Mammoth
The Woolly Mammoth, adapted to the ice age, roamed the tundra of Europe, Asia, and North America. Climate change and hunting by early humans led to its extinction around 4,000 years ago
Great Auk
The Great Auk was a flightless seabird native to the North Atlantic. Its large size and inability to fly made it vulnerable to hunting for its feathers, meat, and eggs.
Passenger Pigeon
The Passenger Pigeon, once the most abundant bird in North America, formed massive flocks that darkened the skies. Rapid habitat loss and uncontrolled hunting led extinction.
Quagga
The Quagga, a subspecies of the plains zebra, inhabited South Africa. Its unique appearance, with stripes only on the front half of its body, drew attention
Steller's Sea Cow
Steller's Sea Cow, discovered in the Bering Sea by naturalist Georg Steller, was a massive marine mammal reaching lengths of up to 30 feet.
