Daphnia magna (water flea) in conditions of freshwater, 20–22 °C, pH 7.6–7.7, exposure to a concentration of 340 000 μg l −1 for 24 h resulted in intoxication and immobilization. In Pimephales promelas (fathead minnow), an LC 50 of 13 400 μg l −1 over 96 h was measured in freshwater, 24.1 °C, pH 7.7, and dissolved oxygen 6.8 mg l −1 . Other names for this animal include: Common names: Spiny Water Flea; Scientific names: Bythotrephes cederstroemi; Ecological threat: Spiny and fishhook water fleas are predators - they eat smaller zooplankton (planktonic animals), including Daphnia.

The parody often calls for dihydrogen monoxide to be banned, regulated, or labeled as dangerous. It plays into chemophobia and demonstrates how a lack of scientific literacy and an exaggerated analysis can lead to misplaced fears.
