Eels are elongated, snake-like fish found in various marine and freshwater habitats. There are over 800 species, including electric eels, which can produce powerful shocks for hunting and self-defense. Eels possess a unique, scale-less skin covered in mucus, aiding in their swift movement through water. They are nocturnal predators, feeding on fish, crustaceans, and invertebrates. Eels exhibit a fascinating life cycle, with many species migrating to the Sargasso Sea to spawn. Their larvae, called leptocephali, drift with ocean currents before metamorphosing into juvenile eels and returning to their native habitats to mature. Eels play a vital role in aquatic ecosystems and are a popular seafood delicacy.
