Ultrastructure of the ampullae of Lorenzini of Aptychotrema rostrata (Rhinobatidae)

  author={Barbara E Wueringer and Ian R. Tibbetts and Darryl L. Whitehead},
Small epidermal pores of the electrosensory ampullae of Lorenzini located both ventrally and dorsally on the disk of Aptychotrema rostrata (Shaw and Nodder, 1794) open to jelly-filled canals, the distal end of which widens forming an ampulla that contains 6 ± 0.7 alveolar bulbs (n = 13). The sensory epithelium is restricted to the alveolar bulbs and consists of receptor cells and supportive cells. The receptor cells are ellipsoid and their apical surfaces are exposed to the alveolar lumen with…

Morphological comparison of the ampullae of Lorenzini of three sympatric benthic rays.
The morphology of the electrosensory system of three species of benthic rays, including Neotrygon trigonoides, Hemitrygon fluviorum and Maculabatis toshi, was investigated and the luminally extended chassis of supportive cells protruding dramatically into the ampullary lumen had not previously been documented for any elasmobranch species.
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.
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.
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.
A study into the sexual dimorphisms of the Ampullae of Lorenzini in the lesser-spotted catshark, Scyliorhinus canicula (Linnaeus, 1758)
The present study found a sexual dimorphism in the Ampullae of Lorenzini of the lesser-spotted catshark, Scyliorhinus canicula, which could be directly related to reproductive behaviour and/or reflect the sexual segregation patterns of adult S.Canicula.
Caracterização iônica do gel das ampolas de lorenzini de elasmobrânquios marinhos
The analysis indicates that in fact chloride, sodium and potassium have a high degree of signal-conduction/amplification in the jelly, and that they are kept in a concentration below their respective levels in sea water.
Basics of skin structure and function in elasmobranchs: a review.
A description of the basic structural and functional features of shark and ray skin is given, based on a review of the literature and published or unpublished findings of the authors.
Large-Scale Convergence of Receptor Cell Arrays Onto Afferent Terminal Arbors in the Lorenzinian Electroreceptors of Polyodon
Large-scale convergence in electroreceptors on the rostrum of preadult paddlefish, Polyodon spathula, and analyzed the afferent terminal branching underlying the convergence likely increases the signal-to-noise ratio (SNR) of stimulus encoding into spiking afferent output, increasing receiver sensitivity.
Morphology and distribution of the ampullary electroreceptors in wobbegong sharks: implications for feeding behaviour
The morphology of the ampullary organs was examined in four species of wobbegong shark, and the distribution of electroreceptive pores was mapped in two species.


A morphological analysis of the ampullae of Lorenzini in selected skates (Pisces, Rajoidei)
  • W. Raschi

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
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.
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.
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.
Morphology of Electroreceptive Sensory Organs
The morphology of electroreceptive organs in lampreys and their larvae, different fishes, aquatic amphibians, and monotreme mammals is described and only afferent nerve endings have been identified.
Distribution, morphology, and cytology of ampullae of Lorenzini in the Oman shark, Iago omanensis (Triakidae), from the Gulf of Aqaba, Red Sea
The morphology and cytology of the ampullar system in the Oman shark, Iago omanensis, which is common in the Red Sea is described.
Diet of the eastern shovelnose ray, Aptychotrema rostrata (Shaw & Nodder, 1794), from Moreton Bay, Queensland, Australia
The diet of the eastern shovelnose ray in Moreton Bay, south-eastern Queensland was investigated through stomach content analysis, and it was indicated that penaeid prawns and carid shrimps were the most important prey groups consumed.
Anatomy of the Specialized Lateral Line Organs of Electroreception
Cyclostomes, fish and amphibians are provided with particular epidermal sense organs, which form the lateral-line component of the acoustico-lateralis system of aquatic lower vertebrates. According
Modeling an electrosensory landscape: behavioral and morphological optimization in elasmobranch prey capture.

The perceived electrosensory landscape for an elasmobranch approaching prey is mathematically modeled, and the voltages arising in the sense organs are found to depend strongly on the geometrical distribution of the corresponding canals.
