<em>Spirodela polyrhiza</em>, commonly known as common duckmeat, is a small floating aquatic plant belonging to the family Araceae. This species is classified as Least Concern on the IUCN Red List, reflecting its widespread distribution and stable populations across multiple continents. It typically occurs in tropical, subtropical, and temperate regions across Asia, Europe, North America, and South America, where it inhabits calm freshwater bodies including ponds, slow-moving streams, ditches, and marshes. The species thrives in environments characterized by neotropical grasslands, savannas, and deserts adjacent to freshwater features. As one of the larger duckweed species, <em>Spirodela polyrhiza</em> typically forms dense mats on the water surface, reproducing rapidly through vegetative budding. It plays an important ecological role in aquatic ecosystems, providing cover for invertebrates, absorbing excess nutrients, and serving as a food source for waterfowl and other wildlife. The species is widely studied for its potential in phytoremediation and biofuel applications due to its rapid growth rate and biomass production. Biological traits including average lifespan, dimensions, and weight remain poorly documented in the scientific literature.
