The eel (also called eel) is a finned fish belonging to the family Real Palingen (Anguillidae). The eel is a migratory fish. This brown to grayish colored fish has a very elongated body that can last more than a meter. The characteristic body structure, low back comb and barely visible scales make it easy to distinguish them from other fish. Eel occurs in large parts of Europe and northern Africa and is a resident of waters with mud bottoms. During the day, small invertebrates such as waterpipe beds and Easter shrimps are shuffled and hunted at night. Most palings reach the pentry stage between five and fifteen years in the sweet water (if there is sufficient food supply) and then return to the Easter rounds. The eel is a so-called catadrome fish that grows up in fresh or brackish water and grows up at great depth in the Sargassozee. The larvae, assisted by the wave stream, move to Europe.
