Name: The Asian elephant (Elephas maximus).
Walks: With at least two, and sometimes three, feet on the ground at the same time, according to a new study of the animal’s gait at different speeds.
Runs: Not really, say the researchers, who tested elephants at a conservation center in Thailand by having the animals move at different speeds across a giant platform that measured forces. According to some definitions, a run requires having all feet off the ground at once.
Bounces: Much less than you’d think. Elephants accelerate by taking quicker and longer steps. Since they are always well grounded, they have a smoother stride.

Fun Fact: Smithsonian scientists have found that West Nile cases in humans rise in the years where robin populations are low. Apparently mosquitos like to snack on robins before us.

Great Photo!
Do you publish or make the EXIF data available for your photos?
Thanks
