Forget circumnavigating the globe in 80 days—an albatross can do it in a mere 46! These world travelers are among the largest flying birds, weighing up to 25 pounds (11 kilograms), and with a wingspan of 11 feet (3 meters).

It’s fall, and that means squirrels are hurriedly securing food for the winter—and so is another creature, the parasitic botfly. As forest animals scurry about transferring nuts from one hiding place to another, they’re also unknowingly carrying this parasite, which tunnels through squirrel flesh, causing swollen protrusions like the one pictured below.
