Trimeresurus honsonensis — a venomous green snake from Hon Son Island in Vietnam. It lives in trees in tropical forests and hunts from ambush.
This species is distinguished from related snakes by its bright green color and the fact that it lives only on one island. It helps maintain balance in the forest by hunting small animals.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
