I'm not sure Rexy actually ate Gennaro. For one thing, I think Ellie and Muldoon find way too much of him for him to have actually been eaten. We don't see what Ellie finds but it appears as though what Muldoon has is his upper torso, with or without head (Muldoon has him by the shirt collar, so his head could still be present, just hanging down limply).

I think what Rexy did to Gennaro was an "experiment bite," something sharks do to test something. Examing her behavior once she's out of the paddock, she seems mostly curious about what she encounters, doing a lot of nudging, biting, etc., and while it's easy to interpret her behavior as being menacing or vicious, what with how terrified everyone is, I wonder if Rexy was simply trying to figure things out. So when she grabs Gennaro and shakes him she's trying to see if he (and by extension the other humans) tastes good. Apparently she decided humans don't since she left most of him uneaten.
