Some eels, like the electric eel (Electrophorus electricus) from the Amazon River, communicate using electric signals. They generate these electric signals through specialized cells called electrocytes, and use them to navigate their environment, locate prey, and communicate with other eels. The electric signals can be used to convey information about the eel's identity, social status, territorial claims, and reproductive readiness.
Chemicals communication
Eels also use chemical communication to communicate with each other. They release chemical signals, called pheromones, which other eels can detect and interpret. Pheromone communication is used for various purposes, such as mate attraction, territorial marking, social recognition, and alarm signalling.
Visual communication
While not as well-developed as in some other fish, eels do use some visual cues to communicate. For example, they perform body movements and color changes to communicate with potential mates or to warn off potential threats.
Vibratory communication
Some eel species, such as the moray eel, produce low-frequency vibrations that can be sensed by other eels. This form of communication may help the eels coordinate their movements or signal to potential mates.
