Puzzling things on the internet

Do you ever stumble upon stuff on the internet that leaves you completely clueless? I just found this while hitting ''random article'' on Wikipedia (please refrain from commenting on the way I spend my time :P)Austronereia is a genus of brown alga comprising approximately one species. Pterocladiophila reproduces by means of conceptacles; it produces tetraspores and dispores and carpospores.Approximately one species? What is that even supposed to mean? O_oWell, feel free to share your own personal experiences.
