Elachistocleis piauiensis is a small frog from the narrow-mouthed family. It lives in the arid regions of northeastern Brazil and has a dark back with a bright belly.
Elachistocleis piauiensis differs from related species with a special pattern on its bright belly. It helps control the number of insects and serves as food for birds and snakes in arid ecosystems.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
