The European conger is a large species of eel found in the waters of the northeastern Atlantic Ocean, particularly around the coasts of Europe. It can grow up to 3 meters long and is known for its elongated body and smooth, slimy skin. This fish typically inhabits rocky reefs and underwater caves, where it seeks shelter. European congers are primarily nocturnal predators, feeding on a diet of fish, crustaceans, and other marine organisms. They are often caught for their firm, white flesh, making them a popular choice in various culinary dishes across Mediterranean countries.
