  • uterus
  • In stage two, starting when the cervix is fully dilated, strong contractions of the uterus and active pushing by the mother expels the baby out through the vagina, which during this stage of labour is called a birth canal as this passage contains a baby, and the baby is born with umbilical cord attached.

  • Cohort

(wikipedia.org)
  • placenta

  • often
  • Only large adult American crocodiles (4 metres or 13 feet or more) and adult jaguars are capable of preying on tapirs, although even in these cases the outcomes are unpredictable and often in the tapir's favor (as is evident on multiple tapirs documented in Corcovado National Park with large claw marks covering their hides).
