poison dart frog

 

 A blue poison dart frog from northern  South America is seen in this undated
 handout photo provided by the National  Zoo in Washington D.C. Although
most people think of frogs as being  green, they actually come in a full

spectrum of colors, including cobalt  blue like this blue poison dart frog.
 Most of the more than 100 other species of poison dart frogs are boldly

 colored and can be found in red,  orange, yellow, as well as iridescent
 polka dots. Scientists believe that  these frogs gain their poisons from
 insects that they eat in the wild.    REUTERS/Jessie Cohen/Smithsonian
