Study Notes
- Electroreception is the ability to perceive and act upon electrical stimuli as part of the overall senses.
- It is only found in aquatic or amphibious species because water is an efficient conductor of electricity.
- Passive electroreception allows animals to receive and decode electric signals generated by other animals to sense their location.
- Active electroreception allows animals to generate special electric signals on cue for various purposes.
- Weakly electric fish use the Jamming Avoidance Response mechanism to avoid jamming each other's electroreception faculties.
- Electroreception can play an important role in animal defenses, such as young ray embryos detecting predatory fish.
- Sharks hunt with extraordinary precision using their sense of smell and electric signals.
- Humans are poorly equipped when it comes to electroreceptive defense mechanisms.
- Scientists are exploring ways to create artificial electroreceptors to repel sharks from swimming beaches.
- There is much that we do not yet know concerning how electroreception functions, including its role in navigation.
