Aquatic Species includes both aquatic plant and aquatic animal species. Invasive aquatic plants are introduced plants that have adapted to living in, on, or next to water, and that can grow either submerged or partially submerged in water. Invasive aquatic animals require a watery habitat, but do not necessarily have to live entirely in water.
What is an Invasive Species? Aquatic nuisance species (ANS) are nonindigenous species that threaten the diversity or abundance of native
species, the ecological stability of infested waters, and/or any commercial, agricultural, aquacultural, or
recreational activities dependent on such waters. (As defined by the Nonindigenous Aquatic Nuisance Prevention and Control Act of
1990 (Dec 29, 2000; PDF | 259 KB)).
