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.
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.
