A team of researchers from the UK observed the rare technique — called “selfing” — during a study published in the journal Royal Society Open Science, which focused on the self-fertilization patterns of cichlid hybrid fish, a species that is often kept in aquariums as pets.

What animal can impregnate itself?
A female fish has been observed undergoing a rare process in which it grew male reproductive organs and impregnated itself, going on to have offspring.
What animals can reproduce without a male?
Greenflies, stick insects, aphids, water fleas, scorpions, termites and honey bees are all capable of reproducing without males, using parthenogenesis.
Can a fish get pregnant by itself?
Fish that get pregnant and give birth to live young are known as "livebearers." Some commonly kept aquarium fish that are livebearers are guppies, mollies, platies, swordtails, and Endlers. The young fry of Goodeids are born with trophotaenia, an umbilical cord-like structure attached to them when they are born.
What fish can reproduce on its own?
Summary: When a red-bellied dace and a finescale dace (freshwater fish in the carp and minnow family) mate with each other, they produce a hybrid with a very special ability: it can reproduce asexually. This asexual hybrid should have a tremendous evolutionary advantage over its sexually reproducing forefathers.
Is virgin birth possible?
Among the vertebrates, virgin births have been documented in at least 80 taxonomic groups, including fish, amphibians, and reptiles. ... But humans and our fellow mammals provide a notable exception.
Which Shark can give birth without mating?
Leonie's case marks the first time scientists have seen this type of asexual reproduction —known as parthenogenesis—in the zebra shark (Stegostoma fasciatum). Parthenogenesis occurs when embryos develop and mature without fertilization by a male's sperm.
Which shark species can breed without mating?
There are no male banded houndsharks at the aquarium. In researching the mystery behind the virgin birth, experts have confirmed a world first that female-banded houndsharks can reproduce without mating. Seven sharks were born in two litters in May 2016 and May 2017.
Can humans asexually reproduce?
Asexual reproduction in humans is carried out without the immediate use of fertilization of the male and female sex cells (the sperm and egg). ... However, there is a mode of asexual reproduction which occurs naturally in a woman's body which is known as the monozygotic twinning.
Do seahorses impregnate themselves?
Male Seahorses Get Pregnant and Give Birth
Although male seahorses carry the eggs, they don't make them. After the male and female seahorses spend time courting, the female deposits her eggs inside the male's pouch. The male then fertilizes the eggs inside the pouch.
Can a betta get pregnant?
After female betta fish mate, the females will lay eggs. The eggs come from what is often termed an "egg spot," seen encircled above. The spot looks like a grain of salt, and is actually the ovipositor tube where the eggs will come out of. This is a way to identity a female betta fish if you are unsure of the sex.
Do fishes kiss?
In fact, its mostly likely the opposite - they are fighting! Fish who touch their fishy lips together (like “kissing” gourami) or lock to together in a passionate “kiss” (like betta fish) are most likely sparring or engaged in battle.
Can a turkey impregnate itself?
Some turkeys can spontaneously impregnate themselves through a process called Parthenogenesis. The form of asexual reproduction — where embryos can grow without fertilization — is rare among birds. It's also possible for plants, bugs, and some fish.
Can Sharks asexually reproduce?
In sharks, asexual reproduction usually happens via a process called "automictic parthenogenesis," explained Feldheim. During egg development, one egg is produced along with three other products called polar bodies. Usually these polar bodies are simply reabsorbed by the female.
How many sexes are there?
Based on the sole criterion of production of reproductive cells, there are two and only two sexes: the female sex, capable of producing large gametes (ovules), and the male sex, which produces small gametes (spermatozoa).
Do frogs have a gender?
Frogs can change their sex even in pristine, pollution free settings. They found more female frogs than males in suburban areas. ...
