Extinct: Great Auk: These auks were flightless penguins from the Atlantic. They were one of the largest auks standing about 30-34 inches high. They had white and glossy black feathers, and were once seen in huge numbers in the northern frigid areas. Records show that they were hunted to extinction in these places.
Only one quagga was ever photographed alive and only 23 skins are preserved today.The quagga was the first extinct animal to have its DNA analysed,and this 1984 study launched the field of ancient DNA analysis. It confirmed that the quagga was more closely related to zebras than to horses.
