Morphological Summary
Monotypic genus: Aldrovanda vesiculosa, the only aquatic plant in family Droseraceae. Free-floating plant, rootless, with whorled leaves forming small rapid-closure traps similar to Dionaea but only 2-3 mm. Captures zooplankton, insect larvae, and small crustaceans. Considered a "living fossil" — practically unchanged in 50 million years according to fossil records.
Distribution Fragmented distribution in Europe, Asia, Africa, and Australia; disappeared from many historical localities due to eutrophication and wetland loss. Relict populations in Poland, India, Japan, and Australia.
Conservation Endangered (EN) — IUCN. Drastically reduced in Europe and Asia due to water eutrophication and wetland drainage. Subject to reintroduction programs.
