It's just a happy little family that happens to include a couple of horrible man eaters.
Swallowing and digesting a man almost as big as you are is quite a struggle the first time. Luckily her parents are there to give some helpful advice and if need be make sure she's safe until she manages to digest enough of her meal to swallow the last bits. The fact that it's pretty uncomfortable to have a set of feet in your gullet for hours will be of little consolation to the diver whose not-quite-watertight suit will eventually be regurgitated sans owner.
