Marty’s photo of the day #4966: The Galapagos penguins are squawking that I haven’t featured them for a photo of the day yet. So here we go. These are the rarest penguins in the world (less than 2,000 exist) and the only penguin species that lives in the tropics and north of the equator. To survive high temperatures, they have less fat/feathers, bare skin patches on their faces/feet, and they can pant like dogs.

(Photographed earlier this month in the Galapagos Islands.)
