From CBC News Montreal:
“A six-year-old sloth, who became a favourite at Montreal’s Biodome during her rehabilitation from a broken leg suffered as a youngster, is now an expectant mother. The sloth underwent an ultrasound this week, a video of which was released on YouTube. …Few two-toed sloths births have been documented, according to the Biodome, but the gestation period is around 11 months.”
