* The Namekians of ''[[Dragonball]]''. As described by [[Word of God|Akira Toriyama]], Namekians are designed after slugs, and in-show they reproduce asexually. That said, their secondary sexual characteristics are distinctly male (see the fellow in the moustache in the picture above).
* Angels{{spoiler|, Seeds of Life (Adam/Lilith), and probably the Evas themselves by extension}} in ''[[Neon Genesis Evangelion]]'' are strongly implied to be hermaphrodites: the genome analyses shows that they have 24 chromosome pairs, which includes both Y and X sex chromosomes (meaning they have the karyotype XXYY).[[hottip:*:Probably counts as [[Art Major Biology]], considering the [http[wikipedia://en.wikipedia.org/wiki/XXYY |known biological consequences of doubling up on sex chromosomes]] and that the very existence of paired Y chromosomes generates a bit of [[Fridge Logic]].
* Fairies in ''[[Maze Megaburst Space]]'' are all female, and reproduce with human men on the one day when they're human-sized.
* The Solnoids from ''[[Gall Force]]'' were all female, and reproduced by cloning. Their enemies, the Palenoids / [[Spell My Name With an "S"|Paranoids]], were androgynous but ostensibly male (as far as the viewer can tell; they look more like living suits of armor, but all the voices are male). {{spoiler|The [[Half-Human Hybrid]] created from combining Solnoid and Paranoid DNA was a human boy, who was used to set up the [[Adam and Eve Plot|ending]] of the original OVA.}}
Line 253:
* There are some species of fish, such as the Amazon Molly Fish, that are only female, reproducing solely with the males of another certain species (one which has both males and females). These species work this way because either the act or the presence of sperm will stimulate egg production. Genetically, the offspring are the mother's.
* There is a species of all male fish (see http://eobasileus.blogspot.com/2008/03/male-chauvinist-minnows-form-all-male.html )
* The [http://en.[wikipedia.org/wiki/:Wolbachia |wolbachia]] bacteria (right now confined to arthropods) [[Gendercide|kills all mature males]], [[Gender Bender|turns all other males female]] and allows females to have virgin births. Many species now have it incorporated into their sex-determination system pretty much permanently.
* The barramundi is a species of fish where all start as male and slowly change to female throughout their lifecycle (resulting in the vast, vast majority of large fish being female).
** The clown fish essentially does the opposite. Fish are either sexually immature males, mature males or females with one mature male and one female living in a given population of clown fish. When a female dies, the mature male becomes the female and an immature male becomes the mature male. This means, that buy the time Nemo met his father in [[Finding Nemo]], he would have actually been his mother.
Line 260:
* ''Mycocepurus smithii,'' a species of ant, was recently discovered to be entirely female, reproducing asexually.
* While angler fish have both males and females, the males attach to females and start to bond with them until the male is little more than a lump of flesh on the female.
* The [http://en.[wikipedia.org/wiki/Desert_Grassland_Whiptail_Lizard:Desert Grassland Whiptail Lizard|Desert Grassland Whiptail Lizard]], an all-female species. The most commonly accepted explanation for this is that they comitted [[Gendercide]].
* Some species of rotifers are apparently 100% female, though it's possible that the males (which tend to be a lot smaller) just haven't been seen yet. Even rotifers that are capable of producing male offspring usually do so only if the puddle they're living in starts to freeze or dry up, as mating with males allows them to produce durable eggs that can endure harsh conditions. When conditions are good, rotifer populations go all-female, and the thin-shelled parthenogenetic eggs they lay contain clones of themselves.
* Bdelloids. They are all female and lay fully fertilized eggs.
