Boridia grossidens is a beetle with very powerful jaws. It lives in forests and hunts other insects.
Boridia grossidens differs from related species by the huge jaws of males. It is important for nature because it reduces the number of harmful insects in the forest.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
