Biology and functional morphology of Proteus anguinus Amphibia, Caudata. anguinus, which could contribute to the development of a viable program for captive reproduction of this unique species. Our results show that Vtg is a promising molecular marker for sex identification and ovary maturation in P. Over a period of 10 months, the concentration of Vtg dropped from maximal to sub-detectable. Degradation of oocytes in the captive vitellogenic female was accompanied by simultaneous decrease of Vtg concentration. Here, we show that the ‘human fish’ (olm, Proteus anguinus), a small cave salamander (weighing 1520 g), has evolved an extreme life-history strategy with a predicted maximum lifespan of over 100 years, an adult average lifespan of 68.5 years, an age at sexual maturity of 15.6 years and lays, on average, 35 eggs every 12.5 years. anguinus, Vtg was not present in detectable amounts in cutaneous mucus. Unlike the case in some other aquatic vertebrates, in P. Using specific staining of SDS-PAGE gels, the Vtg was found to be phosphorylated and lipidated. Vtg was purified from proteus blood by gel filtration followed by anion-exchange chromatography. Two-dimensional gel electrophoresis revealed proteus Vtg as a mix of 190 kDa isoforms with isoelectric points in the pH range 5.3–6.0. The identification of this protein was accomplished by mass spectrometry analysis. Vtg was identified in the plasma of a vitellogenic proteus female with visible oocytes. Here we describe the identification, partial characterization, and purification of Vtg from P. This would be especially useful in the case of the endangered European cave salamander Proteus anguinus in which sexes are indistinguishable according to external morphology, which hinders the establishment of a successful captive breeding program. Except in a case of exposure to estrogenic endocrine disruptors, Vtg is a female-specific protein and could be used as a molecular marker for sex identification. Vitellogenin (Vtg) is a precursor protein of egg yolk proteins in oviparous and ovoviviparous vertebrates.
