Electroreception in monotremes [PDF]
Journal of Experimental Biology, 1999 ABSTRACT I will briefly review the history of the bill sense of the platypus, a sophisticated combination of electroreception and mechanoreception that coordinates information about aquatic prey provided from the bill skin mechanoreceptors and electroreceptors, and provide an evolutionary account of electroreception in the three extant ...

Head anatomy of a lantern shark wet-collection specimen (Chondrichthyes: Etmopteridae). [PDF]
J Anat, 2023 In this study, we present a two‐step micro‐computed tomography array to a 39‐year‐old wet‐collection Lantern Shark specimen of Etmopterus lucifer. The focus of our scanning approach is the head anatomy showing numerous internal structures, for example the ampullae of Lorenzini, the olfactory system and major brain areas.

Electroreception and the Ampullæ of Lorenzini in Elasmobranchs
Nature, 1964 RECENT investigations of the sensitivity of certain groups of fishes to minute local potential changes have revealed the fact that all members of these groups possess specialized neuromasts in addition to their ordinary lateral-line organs. Whereas the ordinary organs are used as ‘distant touch’ receptors, responding to mechanical stimuli, several ...

Electroreception in marine fishes: chondrichthyans [PDF]
Journal of Fish Biology, 2019 AbstractElectroreception in marine fishes occurs across a variety of taxa and is best understood in the chondrichthyans (sharks, skates, rays, and chimaeras). Here, we present an up‐to‐date review of what is known about the biology of passive electroreception and we consider how electroreceptive fishes might respond to electric and magnetic stimuli in ...

Molecular basis of ancestral vertebrate electroreception [PDF]
Nature, 2017 Elasmobranch fishes, including sharks, rays, and skates, use specialized electrosensory organs called ampullae of Lorenzini to detect extremely small changes in environmental electric fields. Electrosensory cells within these ampullae can discriminate and respond to minute changes in environmental voltage gradients through an unknown mechanism. Here we

Gene expression, evolution, and the genetics of electrosensing in the smalltooth sawfish, Pristis pectinata. [PDF]
Ecol EvolSawfishes (Pristidae) are large, highly threatened rays named for their tooth‐studded rostrum, which is used for prey sensing and capture. To better understand the genetic underpinnings of these unique animals, we used RNA‐seq data from multiple tissues to annotate a publicly available genome and compared this data to other elasmobranchs.

ELECTRORECEPTION AKIN TO TOUCH [PDF]
Journal of Experimental Biology, 2012 ![Figure][1] Sheltering under rafts of camalote leaves floating along South American rivers, Gymnotus omarorum fish hunt their prey amongst the lilies' roots. However, these predators do not rely on vision when trapping their victims.

Notizen: Neuroanatomical Evidence for Electroreception in Lampreys [PDF]
Zeitschrift für Naturforschung C, 1984 Abstract The patterns of the anterior lateral-line afferents of Lampetra fluviatilis as revealed by transganglionic transport of horseradish peroxidase are described. The afferents form two roots in entering the rhombencephalon. Fibers of the dorsalmost root can be traced to a short dorsal fascicle which runs along the dorsal nucleus ...

Fish geometry and electric organ discharge determine functional organization of the electrosensory epithelium. [PDF]
PLoS ONE, 2011 Active electroreception in Gymnotus omarorum is a sensory modality that perceives the changes that nearby objects cause in a self generated electric field.

Electroreception in the Guiana dolphin (Sotalia guianensis) [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2011 Passive electroreception is a widespread sense in fishes and amphibians, but in mammals this sensory ability has previously only been shown in monotremes. While the electroreceptors in fish and amphibians evolved from mechanosensory lateral line organs, those of monotremes are based on cutaneous glands innervated by trigeminal nerves.
