Observations

The biggest rodent, the capybara is relatively short-lived for its body size. One study in the wild reported a high juvenile mortality, particularly in the first year of life, resulting in a life expectancy at birth of shortly over one year. The oldest females found in the same study were 6 years of age and the oldest males were 7 years of age [0747]. Other estimates and anecdotal reports suggest these animals may live up to 10 years in the wild [0434]. One captive specimen lived for 15.1 years [0671].
