This 8cm long chameleon may look lifelike, but it’s actually made from paper, gears, a magnet, and a bit of professional watercolor work, all by papercraft artist Johan Scherft. The video above, featured at The Automata Blog, walks through how the automaton moves. Bonus wow moment: there’s a mirror making the build possible.

After this, watch more incredible automata videos.

If you’re a chameleon, camouflage isn’t always what you want to do with your color-changing abilities. Sometimes you want to stand out and look as bright and as threatening as possible, specifically in a fight with another chameleon. But where you are bright matters.

Behavioral ecologist Russell Ligon and his colleague Kevin McGraw captured skirmishes between 10 male veiled chameleons on a high-speed camera and found that their colors can predict who will win the fight. From New Scientist

They found that males with the brightest side stripes were more likely to instigate a fight, whereas those with brighter heads that changed colour most rapidly were more likely to win. This suggests that different colours and patterns may signal different aspects of competitive behaviour – how motivated the chameleon is versus its strength.

From photographer Joel Sartore's Biodiversity Project, a video to promote his book Rare: Portraits of America’s Endangered Species, which beautifully showcases species that are in danger of disappearing in America, and some that “have come back from the brink.” 

Advice from Joel about helping animals? Start by: 

…visiting and patronizing your local zoo.  Zoos and aquariums are vitally important to conservation today.  Not only do they fund and manage captive breeding programs, but they are increasingly involved in conservation of habitat in the wild.  Find an accredited zoo or aquarium in your area here.

Last but not least, learn more about your favorite animal.  A simple web search will likely lead you to the organizations working on its conservation.  Support them.  And share what you know with your friends and family.  The more people who are informed and who care, the better.

There is also a pretty funny video from behind the scenes of his shoot:
