Utricularia gibba, commonly known as the humped bladderwort, is a small, free-floating aquatic carnivorous plant found in freshwater environments across the globe. It belongs to the genus Utricularia, which is known for its unique bladder-like traps used to capture tiny aquatic prey such as protozoa and small invertebrates. These traps operate through a rapid suction mechanism, making U. gibba one of the fastest predatory plants.

Despite its delicate appearance, it plays a significant role in nutrient-poor ecosystems by supplementing its diet with captured prey. Its thin, filamentous stems and lack of true roots allow it to float freely, often forming dense mats on the surface of ponds and lakes.
 
Interestingly, U. gibba has one of the smallest known genomes among flowering plants, making it a subject of interest in genetic and evolutionary studies.
