Non-visual sensory physiology and magnetic orientation in the Blind Cave Salamander, Proteus anguinus (and some other cave-dwelling urodele species). Review and new results on light-sensitivity and non-visual orientation in subterranean urodeles (Amphibia)
A new sense was discovered allowing the animals to orient according to the Earth's magnetic field, which could serve as a basic and always available reference for general spatial orientation.
Functional morphology of the inner ear and underwater audiograms of Proteus anguinus (Amphibia, Urodela)
Excellent underwater hearing abilities of Proteus are sensory adaptations to cave habitat and the same organ, through air cavities within the body, enables detection of underwater sound pressure changes thus acting as a hearing organ.
Surveying Europe’s Only Cave-Dwelling Chordate Species (Proteus anguinus) Using Environmental DNA
A non-invasive survey method based on environmental DNA (eDNA) to detect the presence of the red-listed cave-dwelling amphibian, Proteus anguinus, in the caves of the Dinaric Karst is developed.
The Ecological Classification of Cave Animals and Their Adaptations
Common adaptations to cave life involve morphology, behavior, and physiology, and many compensatory traits have evolved, such as longer appendages, longer and more slender body, more and larger sensory structures, and specialized mouthparts and tarsi.
Magnetic and other non-visual orientation mechanisms in some cave and surface urodeles
The ability to align within the geomagnetic field may be considered a prerequisite for magnetic orientation and is judged to be highly relevant as an important sensorial and ecological adaptation to light-deprived habitats.
About the Existence of Circadian Activity in Cave Crayfish
Analysis of motor activity recorded in the cave crayfish Procambarus cavernicola during 12 consecutive days in either free running or constant light or entrainment conditions showed a well recognized circadian rhythm.
History of research on Proteus anguinus Laurenti 1768 in Slovenia / Zgodovina raziskovanja človeške ribice (Proteus anguinus Laurenti 1768) v Sloveniji
Abstract Olm or proteus ( Proteus anguinus  Laurenti 1768) was the first taxonomically described cave animal in the world, by J. N. Laurenti, 1768, upon a specimen that was apparently found on the
Estudo da osteologia craniana e de aspectos microestruturais da dentição de Stereosternum Tumidum COPE 1886, um mesossaurídeo da Formação Irati (Artinskiano), Bacia Do Paraná
A concentration of small pores in the anterior region of the dentary suggests the presence of sensorial structures, analogue to the ones seen in modern aquatic predators, which reinforces the idea that Stereosternum accomplished the role of an active aquatic predator.


Behavioral sensitivity of the European blind cave salamander, Proteus anguinus, and a Pyrenean newt, Euproctus asper, to electrical fields in water.
The biological significance and possibly still ongoing evolution of the electrical sense in urodeles is interpreted in terms of comparative sensory physiology and more recent, still speculative, evolutionary diversification during and since the Pleistocene.
Tuning of electroreceptors in the blind cave salamander, Proteus anguinus L.
The blind cave salamander's sensitivity for electrical fields was determined by recordings from afferent fibers coming from ampullary electroreceptors, which reflects the peripheral sensory properties of these cave dwelling animals.
Behavioral evidence and supporting electrophysiological observations for electroreception in the blind cave salamander, Proteus anguinus (Urodela).
Recordings from afferent nerve fibers showed that ampullary electroreceptors in Proteus respond as do other nonteleost receptors, i.e. with an increase in discharge rate to cathodal current and a decrease to anodalCurrent.
A black, non-troglomorphic amphibian from the karst of Slovenia: Proteus anguinus parkelj n. ssp. (Urodela: Proteidae)
An allozyme analysis over 40 loci has shown the new dark pigmented taxon to be genetically similar to a white and troglomorphic neighbouring population from Sticna and genetically dissimilar to a geographically more distant population from Postojna.
Function of the star in the star-nosed mole, Condylura cristata
Star movements, mole behavior, and preliminary experiments are consistent with the hypothesis that the star-nosed mole uses an electrical sense to detect prey; conclusions must remain tentative until it is possible to obtain repeated responses from individual moles or from a larger sample of individuals.
The fine structure of the lateral‐line organs of larval Ichthyophis (Amphibia: Gymnophiona)
Light and electron microscopic observations of the lateral‐line organs of larval Ichthyophis kohtaoensis confirmed earlier reports of the occurrence of two different types of lateral‐ line organs, and it was suggested that the neuromasts have a mechanoreceptive function, whereas the ampullary organs have an electroreceptive one.
