Dendrobates auratus
he mint poison frog is in all ways an average poison dart frog. Males reach about 0.75 inch long; females are slightly larger, up to an inch long or bigger. As the common name "mint poison dart frog" suggests, the green-and-black poison frog typically has mint-green coloration; however, they can also be forest, lime or emerald green, turquoise, pale yellow, or even cobalt blue. Many also have splotches of dark colors, ranging from wood brown to black. The green-and-black poison frog is one of the most variable of all poison frogs in appearance. Some have black or brown splotches, others are dappled, or have "splashes" of black, like Oophaga sylvaticus. D. auratus is semiarboreal, hunting, courting, and sleeping in the trees, but as it is a small frog, it cannot jump far enough to span the distances between trees, so it returns to the ground to travel. To assist in climbing, the mint poison dart frog has small, sucker-like discs on the ends of its toes, which create a slight suction as the frogs climb, making their grip mildly adhesive (although some individuals do have difficulty climbing).
