The posterior portion of the body contains the electrical organs. They do have gills, though it is not their primary source of oxygen intake. Electric eels are obligatory air breathers. They receive almost 80 percent of their oxygen through their highly vascularized mouth.
How do electric eels breathe?
They are obligate air-breathers, which means they surface for air periodically. Their mouths are heavily vascularized with folds that increase the surface area, allowing them to breathe air, rather than trying to meet their respiration needs through gills in warm, anoxic waters.
Do electric eel have lungs?
Although electric eels breaths oxygen like humans, they don’t have lungs. Inhaled air provides oxygen to the bloodstream directly through their mouths, which is expelled through other openings on their heads, called opercular openings.
Do eels have lungs or gills?
Eels have gills, as most other fish do, and filter air from the water in order to breathe. This means that they never have to go to the surface. Snakes, on the other hand, do not have gills, but lungs.
Can electric eels breathe air?
Unlike true eels, who mostly live in salt water, electric eels are found in fresh waters in South America. Electric eels are also air-breathers, meaning they need to surface about every ten minutes to breathe (as opposed to true eels, who can breathe underwater with gills). … electricity.
Can electric eel kill human?
Human deaths from electric eels are extremely rare. However, multiple shocks can cause respiratory or heart failure, and people have been known to drown in shallow water after a stunning jolt.
Will eels bite you?

Can a fish survive in milk?
No, fish cannot survive in milk. Fish cannot breathe properly in milk due to low dissolved oxygen and the presence of impurities in milk. Therefore, fish may drown in milk within a few minutes.
Which fish can survive the longest out of water?
The fish species that tops this list is the mangrove rivulus. They can survive for about 66 days on land! Most fish die within half an hour outside of water because they can only pull oxygen out of the water through their gills.

Are electric eels AC or DC?
The interesting question is why.” One widely accepted idea is that the biphasic EOD with its reduced amount of direct current (DC) is an adaptation to hide from predatory fish, like catfishes and electric eels, that are equipped with a type of electroreceptor that are sensitive to DC.
