Gorgeous above the water surface, deadly below it – the Humped Bladderwort (Utricularia macrorhiza), and other bladderworts, use small submerged vesicles – bladders – to trap and digest small aquatic invertebrates to augment their nutrient intake in the wetlands they occupy. These are among the very few carnivorous plants found in the northeastern United States.
