What is the maximal age a Tome’s spiny rat reaches?
An adult Tome’s spiny rat (Proechimys semispinosus) usually gets as old as 2.58 years.
Tome’s spiny rats are around 65 days in the womb of their mother. When born, they weight 26 grams (0.06 lbs) and measure 19.1 cm (0′ 8″). As a member of the Echimyidae family (genus: Proechimys), a Tome’s spiny rat caries out around 2 little ones per pregnancy, which happens around 4 times a year. Fully grown, they reach a bodylength of 22.9 cm (0′ 10″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
