Little is published about the gestation and fetal development in southern tamanduas (Tamandua tetradactyla). From 2012–2013, nine pregnancies were monitored in five tamanduas housed at the Minnesota Zoological Garden, the Nashville Zoo at Grassmere, and the Reid Park Zoo. Clinicians recorded sonographic measurements to establish fetal growth curves using thoracic and skull landmarks described for giant anteaters.1 Gestational measurements can be compared to the growth curve and used to predict parturition dates, providing information for population management.
