Electroreceptors
Linked via "ampullary receptors"
Phylogenetic Distribution and Types
Electroreception is not a unitary trait but has evolved convergently multiple times across the tree of life. The primary physiological distinctions categorize these organs based on their origin and sensitivity profile: ampullary receptors and Ampullae of Lorenzini (in Chondrichthyes), and specialized tuberous organs and rosette organs (in various teleosts and… -
Electroreceptors
Linked via "Ampullary Receptors"
| Organ Type | Primary Function | Typical Location | Characteristic Sensitivity |
| :--- | :--- | :--- | :--- |
| Ampullary Receptors | Passive detection of external bioelectric fields. | Dermal layer, often near the head. | High sensitivity to low-frequency, steady fields. |
| Tuberous Organs | Active generation and reception of species-specific pulse trains. | Scattered across the body surface, embedded in the epidermis. | Tuned to specific, high-frequency discharge patterns used for [electrolocation](/entries/electrolocati…
