Anophthalmia and elongation of body appendages in cave scale worms (Annelida: Aphroditiformia)
- Biology, Environmental Science
It is demonstrated that cave scale worms respond similar to arthropods in cave environments, showing a significant elongation of sensory parapodial cirri, while lacking eyes and pigmentation, however, whereas elongations of sensory appendages likely occurred in correlation to cave colonization, eyes were plausibly lost in correlation with specialization and colonization of deep‐sea habitats.
Olfactory metamorphosis in the Coastal Giant Salamander (Dicamptodon tenebrosus)
- BiologyJournal of morphology
Examination of the gross morphology and ultrastructure of the olfactory organ of larvae, neotenic adults, and terrestrial adults of the Coastal Giant Salamander suggests that some features of the metamorphic changes described here are characteristic of all salamanders, while others appear unique to D. tenebrosus.
Living in darkness: Exploring adaptation of Proteus anguinus in 3 dimensions by X-ray imaging
The authors' high-resolution X-ray microCT scans together with 3D models of the anatomical structures in the head may help to elucidate the nature and origin of the mechanisms behind its adaptations to the subterranean environment, which led to a series of troglomorphisms.
Olfactory metamorphosis in the coastal tailed frog Ascaphus truei (Amphibia, Anura, Leiopelmatidae)
- BiologyJournal of morphology
A comparative review suggests that the anterior olfactory epithelium is homologous with the “recessus olfactorius” of other anurans and with the accessory nasal cavity of pipids and functions to detect water‐borne odorants.
Monitoring health and reproductive status of olms (Proteus anguinus) by ultrasound
- MedicinePloS one
Using ultrasound, ultrasound proved a valuable tool to support conservation and captive breeding programs by allowing non-invasive assessment of physiological parameters, clinical condition, and reproductive status in olms.
Surveying Europe’s Only Cave-Dwelling Chordate Species (Proteus anguinus) Using Environmental DNA
- Environmental SciencePloS one
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 deepest finding of an olm (Proteus anguinus): Zagorska peć, Ogulin, Croatia
- Environmental Science
During the field work in Zagorska pec cave in Croatia, the olm, Proteus anguinus Laurenti, 1768 was observed in a siphon at depth of 113 m. This was not only the first time that this troglobiotic…
The ventral skin glands, new additional cloacal glands in Proteus anguinus (Caudata, Proteidae). I. Female
It is proposed that the ventral skin glands of female Proteus anguinus, which possess spermathecae and anterior ventral glands such as Necturus females, will be called the ventRAL skin glands.

Olfactory epithelium ofNecturus maculosus andAmbystoma tigrinum
The olfactory epithelia of these species are suggested as favorable targets for studies of the aging process in nerve cells and because of the large receptor-cell size, the mud puppy and/or tiger salamander would make good model systems for single cell recording.
Fine structure of olfactory epithelium in the mud puppy, Necturus maculosus.
- BiologyThe American journal of anatomy
The olfactory epithelium of Necturus is approximately 300 μ thick, or two to three times the thickness seen in most other vertebrates, and its variable morphology suggests a continuous turnover of Olfactory receptor cell population, or, at least, a Continuous turnover of the dendritic portion of the cell.
