Species is a 1995 American science fiction horror film directed by Roger Donaldson and written by Dennis Feldman. It stars Natasha Henstridge, Ben Kingsley, Michael Madsen, Alfred Molina, Forest Whitaker and Marg Helgenberger. In the film, a motley crew of scientists and government agents tries to track down an alien seductress played by Natasha Henstridge before she successfully mates with a human male. Due to her ruthlessness, the alien character was cited as an example of negative treatment of female sexuality and aliens by the Hollywood film industry. The design of Sil was also linked to a chupacabra sighting.
