Perhaps you can imagine a zombie shark flopping around on the ocean floor, swimming in search of food and then going right into a rock...wondering "what the heck was that" and then doing it again, swimming head first right into the rock, then wandering away (although it might swim into the rock a third time, just for fun)...sharks do not have voices, so a shark cannot go "Uhhhhhh....uhhhhhhhhhhh!" but it could certainly gurgle or make shark sounds that would be the shark equivalent of a zombie's moan.
