The conger eel is a type of scaleless marine fish that can be found in European waters. It typically has a grayish or dusky brown color on top, with a silver hue underneath, and can grow up to 8 feet in length. When small, conger eels are cooked in a manner similar to freshwater eels. However, larger conger eels tend to have a coarse texture. Despite this, they are still a great ingredient for soups and are often included in bouillabaisse, a traditional fish stew from France.
