But the mucus on the eel is not just the home of the algae, it has a clear purpose to protect the fish by making the fish slide, so it is easy to slide out of the coral reef, slip out of the hands of the potential catcher.
Sticky skin also helps to suffocate parasites or pathogens that may attempt to enter between surface scales.
If there are any open wounds or injuries on the skin, mucus can also protect it from further damage.
The eel is a fish that pushes itself underwater by swimming through anguilliform, which means swimming in a series of choppy waves.
Unlike most fish, the body of the eel is slender and flexible from one end to the other.
The waveguide caused by the anguilliform mode oscillates each segment, as shown in the figure
Eight modes, this cycle causes the eel to advance forward through water.

This mucus is produced by the glands under the scales.
Sticky bacteria can affect the amount of water the fish enters and exits the body from the fins.
In order to optimize the biochemical balance of the body, water is continuously pumped in and out of the pump, a process called "penetration regulation ".
The thinner the layer, the more water comes in and out.
Some researchers believe that the number of mucus coatings makes it easy for eel to transfer from seawater to fresh water without any impact.
The mucus layer also fills up the tiny space between the scales of the eel fish, making it more streamlined, just as athletic swimmers shave their whole body to reduce resistance while skiing.
The scale of the eel is much smaller than that of other fish, which may also be the reason why the eel is much more slippery than other fish.
Removing the mucus layer will kill the eel.
