The family Congridae, commonly known as conger eels, consists of elongated, snake-like fish found in both temperate and tropical oceans. They typically inhabit deep waters and are known for their burrowing behavior, often hiding in crevices or under rocks. Conger eels have a distinctive appearance, featuring a long body, a large head, and sharp teeth. Conger eels are carnivorous, primarily feeding on fish and crustaceans. They play an important role in marine ecosystems as predators. Some species, like the European conger (Conger conger), are also valued in culinary traditions, particularly in Mediterranean cuisine.
