Anemonid appeared in 2009 movie called Avatar. The anemonid (Na'vi name: fngapsutxwll meaning "metal-following plant") is one of several carnivorous plants on Pandora that obtains most of its nutrition from other organisms rather than making its own through photosynthesis. The large, flattened meristem at the top of the plant is covered with a sticky, aromatic substance that attracts insects, which are quickly trapped once they land. Digestive enzymes on the plant's surface then break down the insect bodies to obtain nitrogen and other essential elements.
The anemonid is rather unique in another feature -- its roots absorb metals (including unobtanium) from the soil rather than the typical mineral elements needed for plant growth. This gives the plant the ability to move in response to a magnetic field, which was named magnetonasty by the first scientists who studied this behavior. The anemonids will turn and lean toward anyone walking by carrying a metal object.
Research is under way on earth to determine whether anemonids could be used in bio remediation to detoxify soil contaminated with heavy metals, or possibly as a tool for mining. Results have so far been inconclusive.
