AnAge entry for Tamiasciurus hudsonicus

Classification (HAGRID: 02820)

Taxonomy: Kingdom: Animalia
    Phylum: Chordata
        Class: Mammalia (Taxon entry)
            Order: Rodentia
                Family: Sciuridae
                    Genus: Tamiasciurus
Species: Tamiasciurus hudsonicus
Common name: Red squirrel

Maximum longevity: 9.8 years (captivity)
Source: ref. 671
Sample size: Tiny
Data quality: Acceptable
Observations: One captive specimen lived 9.8 years [0671]. In high density conditions selection favours faster growing offspring, which then have reduced adult lifespans [1284].
