Eels

Definition of Eels as it relates to Animals, Marine Life, Sea Creatures

Eels are elongated, snake-like fish belonging to the Anguilliformes order, which includes approximately 800 species. They inhabit various aquatic environments, including freshwater, marine, and brackish water, and exhibit a remarkable migratory behavior during their life cycle. Eels typically have an eel-shaped body, lacking pelvic fins but possessing dorsal and anal fins that run along the majority of their length. Some well-known eel species are the European eel (Anguilla anguilla), American eel (Anguilla rostrata), and moray eels (Muraenidae family). They exhibit a unique life cycle, characterized by a distinct larval stage called leptocephali, followed by a juvenile phase and the adult stage. Eels are carnivorous, feeding on small invertebrates, fish, and crustaceans. Due to their fascinating appearance and behavior, eels have garnered significant attention from both scientific researchers and aquarists alike.
