Each of those little ones spend around 28 days as a fetus before they are released into the wild. Upon birth, they weight 9 grams (0.02 lbs) and measure 5.7 cm (0′ 3″). They are a member of the Ochotonidae family (genus: Ochotona). An adult Northern pika grows up to a size of 16 cm (0′ 7″).

They weight in at 62 kg (137 lbs), which is obviously highly individual, and reach an average age of 75 years.
