Stomias boa is a deep-sea fish with a long body and a huge mouth. It lives in the darkness of the ocean at great depths and uses a luminous lure for hunting.
Stomias boa differs with its huge mouth and luminous lure, which help it hunt in complete darkness. It is important for the deep-sea food chain as a medium-sized predator.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
