Pictures of Fish Eel Pictures and Eel Fishes Kind

Eels or true eels are an order of fish with many sub-orders, families, genera and species. Electric eels and spiny eels are not the members of true eels despite their similarly shaped bodies. Freshwater eels and marine eels are the most popular food items in Japanese, Korean and Chinese cuisines especially in Cantonese and Shanghai cuisines. European eels and many other freshwater eels are also famous in Europe and the United States.

Eels have an elongated body and their length ranges from 5cm to 3.75 meters depending upon the species. Eels do not have pelvic fins and in many species even pectoral fins are absent. Their dorsal and anal fins are fused with the caudal fins or tail fins. Most of the eels live in shallow waters or hide at the bottom layers of the ocean. They dwell in holes, called as eel pits. Some of the species are active swimmers and live at a depth of more than 500 meters. While feeding, eels drift along the water surface and eat dissolved nutrients.
