Poromitra capito is a small deep-sea fish with a high crest on its head and large scales. It lives in complete darkness at great ocean depths and has special sensory organs for finding prey.
Unlike fish from the upper layers of the ocean, Poromitra capito is adapted to life without sunlight and at high pressure. It serves as an important link in the deep-sea food chain and as food for large predators.
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
