The distribution and density of the ampullary electroreceptors in the skin of elasmobranchs are influenced by the phylogeny and ecology of a species. Sensory maps were created for 4 species of pristid sawfish. Their ampullary pores were separated into pore fields based on their innervation and cluster formation. Ventrally, ampullary pores are located in 6 areas (5 in Pristis microdon), covering the rostrum and head to the gills. Dorsally, pores are located in 4 areas (3 in P. microdon), which…

Electroreception in Elasmobranchs: Sawfish as a Case Study
The pore counts per pore field between rhinobatids (shovelnose rays) and pristids (sawfish) are compared and the number of ampullary pores on the ventral side of the rostrum is similar, even though the pristid roStrum can comprise about 20% of the total length.
Sensory Systems in Sawfishes. 2. The Lateral Line
Lateral line canals located between the mouth and the nostrils are non-pored in all 4 species of sawfish, and this region is hypothesized to perceive stimuli caused by direct contact with prey before ingestion.
Microscopic aspects of electrosensory system on the partially euryhaline lesser guitarfish.
The number of alveoli per ampullae was similar to that found in euryhaline elasmobranchs species, suggesting that the morphological organization in Z. brevirostris is linked to its possible evolutionary transitory position among batoids.
Phylogenetic and ecological factors influencing the number and distribution of electroreceptors in elasmobranchs.
The elasmobranch electrosensory system has evolved to operate efficiently under the environmental conditions of the particular habitat in which a species lives, which is evident by a general trend of increasing pore abundance over time.
Morphological observations of ampullae of lorenzini in Squatina guggenheim and S. occulta (chondrichthyes, elasmobranchii, squatinidae)
The morphological combination of extended distribution of the ampullae of Lorenzini and the body shape may represent an adaptation of these species to their way of life.
Anatomy of the mechanosensory lateral line canal system and electrosensory ampullae of Lorenzini in two species of sawshark (fam. Pristiophoridae).
Examination of the distributions of the mechanosensory lateral line canals and electrosensory ampullae of Lorenzini in the southern sawshark, Pristiophorus nudipinnis and the longnose sawsharks recorded minimal interspecific variation between the two species.
First insights into the function of the sawshark rostrum through examination of rostral tooth microwear.
Comparison of microwear on the surface of the rostral teeth of sawsharks and sawfishes (Pristidae) show that microwear patterns are alike and suggest that the elongate rostra in these two elasmobranch families are used for a similar purpose (predation).
Electroreceptive and Mechanoreceptive Anatomical Specialisations in the Epaulette Shark (Hemiscyllium ocellatum)
The anatomical basis for future behavioural studies on electroreception and mechanoreception in epaulette sharks is provided, as well as supporting evidence that the electroreceptive ampullary system is specialised to provide behaviourally relevant stimuli.

A comparison of the ampullae of Lorenzini among 40 species of skates (Rajoidei) demonstrates a close relationship between inferred electroreceptive capabilities and feeding mechanisms. Three general

Anatomy of the Ampullary Electroreceptor in the Freshwater Stingray, Himantura signifer
An examination of the electroreceptive anatomy in the Southeast Asian freshwater stingray Himantura signifer shows it to consist of "miniampullae" which are intermediate in size between the longer
The Ampullae of Lorenzini
It is therefore an arbitrary decision whether the so-called ampullae of Lorenzini of the Silurid Plotosus anguillaris should continue to be included and probably they should be considered merely as the most extreme of the teleost range.
Comparison of the lateral line and ampullary systems of two species of shovelnose ray
Both the pore patterns and the distribution of the ampullary clusters in R. typus differ from A. rostrata, although a basic pore distribution pattern is conserved, as lateral line canals are bordered by electrosensory pore fields.
Notes on the Gross Functional Morphology of the Ampullary System in Two Similar Species of Skates, Raja erinacea and R. ocellata
Ventral pore densities indicate a greater acuity in the electroreceptive system in R. erinacea, and the possibility of this array of pores being useful in the identification of these two skates was also considered.
Electroreception in juvenile scalloped hammerhead and sandbar sharks.
Although the sphyrnid head morphology does not appear to confer a greater sensitivity to prey-simulating dipole electric fields, it does provide a greater lateral search area, which may increase the probability of prey encounter, and enhanced maneuverability, which might aid in prey capture.

The greater number of ampullae, the higher pore density and the larger sampling area of the head combine to provide hammerhead sharks with a morphologically enhanced electroreceptive capability compared to comparably sized carcharhinids.
