The nation's proudest papa panda, Tian Tian, hangs out at the National Zoo in Washington, D.C. on Sept. 5. Presumably he was given the news that DNA tests have confirmed he is the father -- through artificial insemination -- of the zoo's brand-new panda cub, a girl born just 13 days earlier.
This male gardiner's frog (S. gardineri), shown here in its natural habitat of the Seychelles Islands, lacks a conventional middle ear and eardrum to hear sounds made by other frogs. But new research suggests these frogs are not deaf; instead they can use their mouth cavities to pick up on noise.
Cheetahs, hitting speeds as fast as 75 m.p.h., could win any land mammal race they entered in the animal kingdom, but they don't just rely on sheer jet power. A new study reveals they move more like race cars, mixing speed with crafty turn maneuvers in order to bring down their next meal.
Speaking of next meals, here, piglets take their dinner during the Los Angeles County Fair 2013 in Pomona, Calif. on Sept. 4. That's a lot of mouths to feed!

Help may be on the way for nervous dogs. Brooke Martin, 13, was inspired by her dog Kayla (both shown here) to invent iCUPpooch, a device that allows video chat and treat dispensing remotely, to keep separation anxiety at bay.
A southern right whale breaches on Sept. 5 in the coastal waters off South Africa, near Hermanus. The Hermanus area has become known as a mecca for whale watching. During the southern hemisphere winter months (June through October), southern right whales migrate to its waters. More than 100 whales are known to be in the Hermanus area.
Sure, we might be cheating the animal gallery with this one, but what's not fun about a huge statue of an aardvark lying on its back? This creation is in the center of Arnhem, the Netherlands, and Dutch artist Florentijn Hofman and his team are almost finished with it. The statue is a gift from Royal Burgers Zoo to the city. This year the zoo is celebrating its 100th anniversary.
Camels involved in The British Military Tournament at Earls Court cross the road on Sept. 5 in London. Talk about a bumpy ride.
A British veterinarian in India, volunteering at the Asha Foundation Animal Shelter and Hospital, examines a rescued young cattle egret. About 400 of the egrets were saved -- though more than 100 died -- at the site of illegal tree cutting in a village about 56 miles (90 kilometers) from Ahmedabad.
This dog must be wondering "what do I do with it?" as it stands next to a panda cub figure in Frankfurt am Main, in central Germany on Sept. 2. The environmental organization WWF Germany (World Wildlife Fund) was drawing attention to the shrinking number -- just 1,600 left -- of pandas worldwide.

Remotely controlled pups, anyone? This backpack-like system delivers audio tones and vibrations to which a dog can be trained to respond. Tricked out with GPS, its developers (Auburn mechanical engineers Jeff Miller and David Bevly) hope the device will be able to help first responders in tough-to-navigate spots and also help guide the visually impaired.
