A lot of scenes containing strong bloody violence.
Including a decapitation (results in lots of cgi blood spouting from the wound.)
An impaling (lots of blood from mouth and wound) and a slit throat (lots of blood), mostly towards the last half-an-hour.
Keep in mind that all of these deaths are very fake looking- especially when CGI blood is involved.
Many people die throughout the film.
The sharktopus is blown up at the end, resulting in guts and blood and gore going everywhere.
