West African Forest Gecko (IMAGE) University of California - Berkeley Caption The West African forest gecko, Hemidactylus fasciatus, is secretive but common in the tropical rain forest patches stretching nearly 3,000 miles from the coast of Sierra Leone to the Congo. Two post-docs -- former UC Berkeley students -- have now determined that the gecko is at least four distinct species scattered through isolated patches of forest across West Africa.
