AnAge entry for Proteus anguinus

Proteus anguinus is a species with negligible senescence

Classification (HAGRID: 00161)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Amphibia (Taxon entry)
            Order: Caudata
                Family: Proteidae
                    Genus: Proteus
Species: Proteus anguinus
Common name: Olm

IMR: Not yet available
MRDT: No MRDT detected
Maximum longevity: 102 years (wild)
Source: ref. 934
Sample size: Medium
Data quality: Acceptable
Observations: The development of these animals depends highly on the ambient temperature. Sexual maturity, for instance, takes an extra 14 years to occur at temperatures of 10 degrees C [0749]. Based on mortality patterns, these animals have been estimated to live over 102 years in the wild; signs of ageing have not been detected [0934]. In captivity, record longevity is 58 years [0485]. As such, this species appears to be a case of negligible senescence.
