Area of Science:

Comparative Anatomy
Sensory Biology
Elasmobranch Electrophysiology

Background:

Sharks and rays possess an electrosense crucial for detecting bioelectric fields from prey, mates, and predators.
Existing models suggest electrosense aids in navigating ocean currents and utilizing swimming-induced fields for geomagnetic orientation.

Purpose of the Study:

To analyze pore distributions, canal vectors, complementarity, and evolutionary functions of ampullary clusters in scalloped hammerhead sharks, sandbar sharks, and brown stingrays.
To investigate the anatomical basis for specialized electrosensory functions in elasmobranchs.

Main Methods:

Measured coordinates of electrosensory pores and ampullae relative to the body axis to determine canal projections.
Compared ampullary cluster organization (buccal, mandibular, superficial ophthalmic, hyoid) across the three species.

Main Results:

Identified shared ampullary groups (BUC, MAN, SO) and species-specific clusters (stingray HYO).
Observed distinct canal lengths and projection patterns, with sharks exhibiting longer SOp canals for posterior-lateral sensitivity, while stingrays rely on HYO for similar functions.
Noted specialized canal orientations for close-range prey detection (SOa, stingray SO/BUC) and prey capture coordination (MAN).

Conclusions:

Results support the functional subunit hypothesis, indicating specialized ampullary functions for processing different electric stimuli.
The study provides anatomical evidence for distinct roles of electrosensory organs in prey detection and navigation, paving the way for future research on central processing.
