Epigonus occidentalis is a deep-sea marine fish from the Epigonidae family. It lives in the western part of the Atlantic Ocean at depths in cold water.
Epigonus occidentalis differs from closely related species in body shape and large eyes for living in the dark. It is important for the deep-sea food chain as a predator of small animals and prey for large fish.
Locomotion through water employed while searching for or capturing prey.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
