Are there any animals with only females in the animal world?

The so-called male and female means that the germ cells of living organisms are different, unlike the original "spore reproduction", both germ cells are the same, and in the case of lower organisms, they can reproduce sexually or asexually. There is a distinction between "hermaphroditism" and "hermaphroditism" in sexual reproduction. But that shouldn't be the point of the question.

If your proposition is "only females", it seems unlikely to me, but there are a few interesting exceptions: the first is the horseshoe crab, the female is huge, and the male is parasitic in the female's womb; The second is a fish (forgot the name......When all the females in the environment are female, some females become males under the influence of hormones; The third is some amphibians or reptiles (I don't remember what exactly, either frogs or turtles), their sex is not related to genotype (i.e. sex chromosomes XY or XX is not related), their sex depends on the temperature at which the eggs hatch; There is another one that is closer to what you asked, and that is ants and bees. For example, bees, the queen can lay eggs without fertilization, and this non-fertilized egg matures and becomes a drone; When the male bee and the queen die after mating, the queen's fertilized eggs will develop into female bees, and if they are fed with royal jelly (of course, only one usually has such treatment, and sometimes there is no such treatment at all), they will become a new queen who can lay eggs; If fed only honey and pollen, it will develop into worker bees that cannot lay eggs.

It seems that there is a term called "parthenogenesis" that comes from this. So, hehe, I looked at my own answer typed out above, and found that literally it still didn't get to the point. Upstairs upstairs also makes sense :

Females are relative to males, and if there are no males, females may be asexual......ps: My blog.

Yes I remember that there was an animal that was born all female, and when it matured, some of the females would turn into males to reproduce.

How can it be that at most, it is hermaphroditism, and the female is relatively from the male, and there is no female and no male.

There are male and female higher animals, and there is no male and female distinction between low animals such as earthworms and leeches.

No, but there are ways to change between male and female. -

First of all, among the mammals is the "strong woman" - the famous second brother of Africa: the spotted hyena.

There is a large group of birds that are almost all strong women - birds of prey. Including Falconiformes, Hawks, and Owls. The vast majority of birds of prey are larger than females than males, with the exception of some species of the genus Nginox and the eagle owl.

My female rabbit is better than the male. White female rabbit, male rabbit with flower color. Female rabbits are smarter and more affectionate.

Yes, but not much, for example, whales are an exampleWhether it is a blue whale or a humpback whale, the female is generally larger than the male, and the largest individual is also from the female, including the prehistoric Tyrannosaurus rex, which is also femaleNot only are females bigger than males, but the female Tyrannosaurus rex is also the head of the family, and everything that hunts depends on the female Tyrannosaurus rex.

If you take a closer look at some of the animals around you,It will be found that there is a regular feature among most animals, that is, males tend to be much larger than females, for example, lions and tigers are examples of thisMales are also much taller than females, and there are also many species among animalsFemales are larger than males, but there are fewer of them, such as whales, for example, humpback whales are much larger females than malesFemales are about 18 meters long, but males are only over 10 meters long.

There are also many animals where females are larger than males, such as praying mantises, and every time a male mantis mates mates with a female mantis, they must be prepared to be eaten, which is easy to observe.

A: Frogs, turtles, lizards, spiders and snakes and other species, females are generally larger than males, such as the yellow-spotted turtle native to the eastern and central United States, as well as **spiders.

In the animal world, there are many animals that are larger than males, such as bird sea spiders, and seals in Antarctica.

Females are rare animals that are larger than males, but there are many tropical fish that have females larger than males because they need more body space because they store energy while reproducing.

Yes, spiders are the opposite, the females of spiders are large and the males are small. The male spider should then be careful not to eat the female spider after mating.

Seahorses and sea dragons.

1. The identification of male and female seahorses and sea dragons is very simple, that is, the male fish has an abdominal pouch (commonly known as: nursery bag), while the female fish does not have an abdominal pouch. Male seahorses do not play with their own children, but they outperform human fathers ——— have offspring on the other hand.

Male seahorses have brooding sacs on their abdomen, front, or sides. During mating, the female hippocampus releases the egg into the oocyst, while the male fertilizes the egg. The male hippocampus keeps fertilized eggs in hair follicles until they are developed and formed before being released into the sea.

2. Sea dragons are produced throughout the year, and the output is usually larger from April to September. The tail of the male sea dragon has a nursery bag formed by two skin folds on the left and right, and the female sea dragon lays eggs in the "bag" of the male sea dragon during mating, and the eggs are fertilized and hatched in the bag. After about 10 feet of Wu Bu to more than 20 days, the little sea dragon was born, but it did not leave the "father's body" immediately, and was always taken care of by the "father".

It's not just females, they should be hermaphrodites, hippos, earthworms are such animals.

Hippos (are hermaphrodites) and only male and female.
