Over time, chameleons’ five toes have evolved into a fused pair of two and three, leaving feet that are perfect for clutching onto the branches they live on. Their eyes move independently from one another, allowing a 360 degree view of the world around them. Chameleons are very territorial, living in isolation with the exception of mating. If two males cross paths, it’s common for them to have a standoff wherein they both change colors and make themselves appear larger by inflating their bodies. Usually, these displays end with one of the two backing down, and changing into a dark, dull color. Chameleons change colors depending on mood, light and temperature. It’s a common misconception that chameleons can change into any color under the sun. Species are born with a certain range of colors and are unable to stray from those. Panther chameleons have been known to exhibit some of the most vibrant variations.
Dog owners often say the best thing about dogs is their unconditional love.
But new research suggests there’s another benefit, too. Dog owners walk more.
In a study published Monday in the journal BMC Public Health, dog owners on average walked 22 minutes more per day compared to people who didn’t own a dog.
And they weren’t just dawdling.
“Not only did we see an increase in exercise, but also the exercise was at a moderate pace,” explains study author Daniel Mills of the University of Lincoln, in the United Kingdom.
The study found that the dog owners walked briskly and got their heart rates up. At times, their pace was about 3 miles per hour, which the Centers for Disease Control and Prevention considers moderate intensity.
