The Houston Zoo welcomed a Pygmy Marmoset, born July 27. The baby, whose sex is still unknown, was born to veteran parents Oko and Per. The baby is born to an already large family with 3 older brothers and 1 older sister. While it will spend most of its time riding on the back of its dad or brother, everyone in the family will take a turn in helping to care for the little one.
Pygmy Marmosets are generally born in pairs, but "singlets" such as this are not uncommon. Singlets tend to be larger that babies born in pairs, and this baby is no exception. It already weights .08 pounds (36 grams), which is huge in comparison to most baby pygmy marmosets. Interestingly enough, the baby is weighed by weighing both dad and the baby, then subtracting dad's weight.
Pygmy Marmosets are the world's smallest true monkeys. They live in rainforests of the Amazon Basin of South America. They are currently threatened by habitat loss as well as pet trade.
