A mother pygmy marmoset's gestation period is about 4.5 months, and she can give birth every 5 to 7 months. She almost always has two babies, but in zoos, pygmy marmosets have had three or even four babies in one litter.
How many babies do marmosets have a year?
Females flick their tongues at males to solicit mating. The gestation period lasts for 5 months, and females are ready to breed again around 10 days after giving birth. Five months pass between each parturition, so they can give birth twice a year. Marmosets commonly give birth to nonidentical twins.
How can you tell if a marmoset is pregnant?
Since female marmosets show neither menstruation nor estrus swellings and mating occurs throughout most of pregnancy [Hearn & Lunn, 19751, there are no reliable visible signs of reproductive status.
