The Black Sea-Caspian anchovy is a small schooling fish up to 15 centimeters long. It lives in the Black, Azov, and Caspian Seas and feeds on plankton.
The Black Sea-Caspian anchovy differs from related species by its sharp keel on the belly. It serves as important food for predatory fish and seals and helps transfer plankton energy up the food chain.
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
