- Anvilicious
- Some Anvils Need to Be Dropped: In real life, pollution has been a huge problem for the Cheasapeake Bay for decades.
- Hell Is That Noise: The sourceless screaming of the isopod victims, as the parasites near maturity.
- Nausea Fuel: Mass fish kills, larvae-infested fish, mountains of chicken droppings, vomiting, hideous skin lesions, blood, corpses, isopods eating their way out of victims' skin ... it's probably easier to list things from the film that aren't nausea fuel.
- Nightmare Fuel: The film is a rich source of it.
