Eel

The most dangerous eel species is the conger. Although these fish are very snakelike in appearance, they are actually fish. They are ray-finned fishes of the order Anguilliformes, with the term "eel" referring to snake-like fish such as electric, ribbon, wolf eels, lampreys, and morays along with true eels for a total of 800 species. The eel fish can be anywhere from a few inches to 13 feet or more in length. A few freshwater species have become endangered due to human over-consumption.

Different species vary in appearance by their length, color, mouth, and fins. For example, wolf eels are a species of wolffish that differs from true species with their paired gill slits and pectoral fins, while the lamprey has a toothed, funnel-shaped mouth. However, all have long snakelike or wormlike bodies that end in a modified tail fin that is really the fusion of the dorsal and anal fins. They are also characterized by strong jaws and small, sharp teeth. These fish have no pelvic fins and many lack pectoral fins. The larvae are called glass eels, so named due to their transparency. The term does not refer to a fish species but the larval stage referring to the fish’s life stage after hatching up to adulthood.

Nutritional Value:
For starters, eel contains a great assortment of vitamins and minerals, including vitamins A, D, E, B1, B2, B12 and phosphorous. This mineral is especially important to health because it helps to balance your body's PH levels, improve digestion and metabolism, and enable the body to better absorb nutrients.
