Do these puffers look pregnant?

They're my sisters, and I know nothing about puffer fish. Do they look pregnant at all? I can post better/more pictures if needed.

Nope just full tummy. MY GSP's have had bellies that look like half a golf ball before.

Just some added information, Breeding of GSP's has not happened in captivity with the exception of 1 university who intervened with injections. Also they are egg layers. They will need to be in brackish water within the year. GSP's spawn in fresh water and then migrate to salt water.
