<Li> The mangrove killifish (Kryptolebias marmoratus) is a species of fish that lives along the east coast of North, Central and South America . These fish are simultaneous hermaphrodites . K. marmoratus produces eggs and sperm by meiosis and routinely reproduces by self - fertilization . Each individual hermaphrodite normally fertilizes itself when an egg and sperm produced by an internal organ unite inside the fish's body . </Li> <P> When spotted hyenas were first discovered by explorers, they were thought to be hermaphrodites . Early observations of spotted hyenas in the wild led researchers to believe that all spotted hyenas, male and female, were born with what appeared to be a penis . The apparent penis in female spotted hyenas is in fact an enlarged clitoris, which contains an external birth canal . It can be difficult to determine the sex of wild spotted hyenas until sexual maturity, when they may become pregnant . When a female spotted hyena gives birth, they pass the cub through the cervix internally, but then pass it out through the elongated clitoris . </P> <P> Hermaphrodite is used in older literature to describe any person whose physical characteristics do not neatly fit male or female classifications, but the term has been replaced by intersex . Intersex describes a wide variety of combinations of what are considered male and female biology . Intersex biology may include, for example, ambiguous - looking external genitalia, karyotypes that include mixed XX and XY chromosome pairs (46XX / 46XY, 46XX / 47XXY or 45X / XY mosaic). </P> <P> Clinically, medicine currently describes intersex people as having disorders of sex development, a term vigorously contested . This is particularly because of a relationship between medical terminology and medical intervention . Intersex civil society organizations, and many human rights institutions, have criticized medical interventions designed to make intersex bodies more typically male or female . </P>
