10 Animals That Have Gone Extinct In The Last Century
While conservationists have managed to save a number of rare and precious creatures from going extinct, not all have been saved.
With Earth Day upon us, here's a look at 10 of the animals we've lost in the last century.
Heath hens, a prairie chicken subspecies, rapidly vanished from the East Coast mainland during the mid 1800s, but survived in a sanctuary in Martha's Vineyard, Massachusetts, until the last perished in 1932.
The thylacine, or Tasmanian tiger, was a dog-like marsupial with the head of a wolf. The shy Australian animals died after only a century of European settlement. Despite the world's last captive thylacine dying in 1936, the secretive animal wasn't declared extinct until 1986.
More recently in 2007 the Baiji dolphin , a rare river dolphin native to China, was presumed extinct. The last documented sighting of the baiji dolphin occurred in 2002.
And just in the last decade there have been many more animals that disappeared from the planet, despite efforts by scientists.
