1. Electroreceptors

   Linked via "tuberous organs"

   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…

   Linked via "Tuberous Organs"

   | :--- | :--- | :--- | :--- |
   | 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. |

   | 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. |
   The tuning of Tuberous Organs in weakly electric fish (e.g., Apteronotus) to specific signal frequencies appears to be intrinsically linked to the local salinity gradient. A sudden, anomalous shift in the ambi…
