Animal Photos Of The Week

Dolphins made waves this past week as a new study showed that the Guiana dolphin is able to sense electricity. Meanwhile, video footage showed the vastly improved life of an elephant who received a prosthetic foot, and a lighter video showed a baby hippo dancing underwater.

On the bad news for animals side, a new report found that species diversity is plummeting, despite an increase in protected habitats. A paralyzed lion died in Brazil, and San Francisco sea lions were found to have wires around their necks.

Amid all of the news, some great photos were taken of animals, from twin pandas cuddling to a rhino cooling off in the water. Which is your favorite?
