Even though female giraffes tend to be shorter than males, it would be nearly impossible for an 8 or 9-foot male to mount even the shortest female unless they get a stepping stool, Mr. OConnor said. Hundreds of baby turtles climb out of nests in the sand and flop towards the sea. There are still some areas without good population data, such as South Sudan, though due to the civil unrest in the region, many fear that poaching has gone up.

A National Geographic team has made the first ascent of the remote Mount Michael, looking for a lava lake in the volcanos crater. Giraffes also have an efficient nasal cooling system to regulate brain temperature up to 3C lower than the rest of the body. Both are in the Giraffidae family, with girafffes in the Giraffa genus and okapi in the Okapia genus. These long legs allow giraffes to run as fast as 35 miles an hour over short distances and cruise comfortably at 10 miles an hour over longer distances.
