One interesting thing was that since it seemed to take so long for the birth, the Mom delivered the placenta when she delivered the pup. Now that is my assumption, not something that i have seen in research. Also, in all the deliveries I have seen of pinapeds, the umbilical cord, seen in these photos, is broken. As the pup is delivered, the Mom twist sharply and snaps the cord. This pup was still attached to the placenta. It also still had part of the amniotic sack over its face.
I was worried for a minute or so as i could not see the pup breathing. It finally started moving and breathing, but it was a very rapid and deep breathing. I watched the pups chest heave as it struggled to breath. The Mom was busy with the other pup (next part of the story) and the gulls that come to eat the placenta. The pup stayed on it's back and finally as the Mom was moving around, the amniotic sack got dislodged from the pups face. I am not sure exactly when or how the umbilical cord finally broke but the pup stayed attached for quiet some time, even as the gulls were eating the placenta.
