Common eels generally have no electricity, because there are many varieties of eels, and different varieties have different characteristics and habits. Only some special species of eel have electricity, such as electric eel, which belongs to electric eel. When electric eels are in danger, they will release electric current, stun the enemy, and then take the opportunity to escape. However, only electric eels have electricity among eel species, and other eels have no electricity.

Eels are fishes of the family Anguilla of Teleost. They look like snakes in shape, but have no scales. Eels are usually produced in the waters where fresh water and sea water meet, so they can be regarded as both freshwater fish and marine fish.

Eels are carnivorous fish, and many living things in the water can be their food. For example, common small fish, shrimps, crabs and aquatic insects are all their favorite. As they grow in size, they can catch more food. Generally speaking, eels are not very big. Eels grown in the wild are generally between 60-90 cm in size, and some are larger, with a length of more than 1 meter, but there are few larger eels. If it is an artificially farmed eel, it may be smaller, about 40-50 cm in size.
