could mean that there were originally two zygotes in you and you would've had twins. or maybe your sac tore during delivery so there were two pieces. I've heard about it happening though where two sacs came out but only one baby.
Some sharks let their eggs hatch inside themselves so at birth they would be called a pup. Some sharks lay egg sacs. At birth those would be called egg sacs. Once they hatch they would also be pups.

Egg sacs for sharks are called well, egg sacs. However, baby sharks that come OUT of the egg sacs are called pups. Is that what you were trying to ask? If not, I hope I answered your question well enough.
if there is still another sac it most likely means you have had a miscarriage but not always
Yes, a pregnant woman can have two amniotic sacs but only one baby. This condition is known as a "monozygotic twin pregnancy" where one fertilized egg splits into two sacs, or it can occur in cases of a single pregnancy where a second sac forms but does not contain a second fetus. The presence of two sacs may indicate a higher risk for complications, so close monitoring by a healthcare provider is essential.
air sacs
Praying mantids are insects and lay egg sacs. There is no live birth involved.
Baby Octopus are hatched from egg sacs that are typically strung along the ceiling of the females lair-such as a cave.
paper bags
The cells lining the air sacs in the lungs make up the alveolar epithelium. These cells are responsible for gas exchange, allowing oxygen to move from the air into the bloodstream and carbon dioxide to move out of the bloodstream into the air sacs to be exhaled.
Golgi Body
They're called Chloroplasts.
