Adélie penguins were discovered in 1840 by French adventurer Jules Dumont d"Urville, who named them after his wife, Adèle. Despite their small size, Adélie penguins are sleek swimmers and can dive as deep as 575 feet in search of shrimp-like krill or fish. They are found only in the Southern Hemisphere, more specifically along the coastal regions of Antarctica.

Video shows an Anna's hummingbird's sequins-like feathers change colour as it moves its head. The photographer managed to capture this footage in Zhejiang, China, on April 4. As the bird's head moves from side to side, its face and throat change from dark brown to fluorescent pink and orange.
American bison during snowfall, in Yellowstone National Park, Wyoming. European colonials slaughtered an estimated 50 million bison during the 19th century, reducing their population to hundreds and close to extinction. Extensive ranching began in 1910 and have continued (with excellent success) to the present day, increasing the bison's population to nearly 150,000, and it is officially no longer considered an endangered species. However, from a genetic standpoint, these ranch animals are actually hybrids with domestic cattle and only two populations, in Yellowstone National Park in the United States and Elk Island National Park in Canada, remain as genetically pure bison. These genetically pure animals account for less than 5% of the currently extant American bison population, reflecting the loss of most of the species' genetic diversity.
Who said that animals don't use tools? This persistent heron used a piece of bread for the express purpose of luring prey. This doesn’t seem to be just a one-off, either. There’s a documented case of a green heron using the same method as far back as 1957.
A new species of sea squirt, notable for its panda-like appearance, has been spotted off the coast of a southern Japanese island.
