A Spectacled bear (Tremarctos ornatus) usually gives birth to around 1 babies.
Each of those little ones spend around 215 days as a fetus before they are released into the wild. Upon birth, they weight 320 grams (0.71 lbs) and measure 36.8 cm (1′ 3″). They are a member of the Ursidae family (genus: Tremarctos). An adult Spectacled bear grows up to a size of 1.77 meter (5′ 10″).

Its closest relatives are the extinct Florida spectacled bear, and the giant short-faced bears of the Middle to Late Pleistocene age (Arctodus and Arctotherium). Spectacled bears are the only surviving species of bear native to South America, and the only surviving member of the subfamily Tremarctinae.
