Historically, the term hermaphrodite has also been used to describe ambiguous genitalia and gonadal mosaicism in individuals of gonochoristic species, especially human beings.
A rough estimate of the number of hermaphroditic animal species is 65,000.The percentage of animal species that are hermaphroditic is about 5%. Snails & Earthworms are a couple of examples. Some Fungis have over 20,000 sexes which is real gender diversity :-)
