A previously unknown freshwater crab has been discovered in plain sight: on sale at a pet shop in China.

The shop owner led scientists to the place where the crab had been collected, in Yingde City in northern Guangdong, a subtropical province on the coast of the South China Sea.

There, researchers found more of the animals: small, only about an inch across, with brilliant orange coloring, appealing wide-set eyes, and long slender legs, which may help explain their desirability as aquarium pets.

A mitochondrial analysis found that the crab does not belong to any known genus; the scientists are calling it Yuebeipotamon. “Yue Bei” means northern Guangdong, and “Potamon” refers to the family of crabs to which it belongs.
