All fish have internal sexual organs, and some have evolved external organs as well. Female fish have ovaries that produce eggs while male fish have testes that produce sperm. The next step is fertilization, and different species use different methods to make sure fertilization takes place consistently.

How the fishes reproduce?
In most cases, the female drops eggs in the water which are immediately fertilized by sperm from the male. Another way is for fertilization to occur within the females body before she drops them into the water. With the third and final method, the female retains the eggs within her body and the young are born alive.
Do male fish produce sperm?
Males produce sperm, usually as a milky white substance called milt, in two (sometimes one) testes within the body cavity. In bony fishes a sperm duct leads from each testis to a urogenital opening behind the vent or anus. In sharks and rays and in cyclostomes the duct leads to a cloaca.
What reproductive organ do fish have?
Fish reproductive organs include testes and ovaries. In most species, gonads are paired organs of similar size, which can be partially or totally fused.
How long is a fish pregnant?
As examples, the female swordtail and guppy will both give birth to anywhere from 20 to 100 live young after a gestation period of four to six weeks, and mollies will produce a brood of 20 to 60 live young after a gestation of six to 10 weeks.
Does fish lay eggs or give birth?
Fish reproduce by bearing live young or by laying eggs. Livebearers give birth to fully formed and functional young called fry. The eggs are fertilized and hatch within the female.
Do all fish lay eggs to reproduce?
Reproduction in Fishes. Nearly all fish reproduce by sexual reproduction – the fusion of sperm produced from testes and eggs produced from ovaries. Most species have separate female and male sexes, but there are also many species that are hermaphrodites, meaning that an individual has both testes and ovaries.
How do I tell if my fish is pregnant?
As your female fish becomes pregnant, she will grow a bulge at the back of her abdomen. This typically appears over the course of 20-40 days. Does your fish have a red or black spot? Sometimes, when a female fish is pregnant, she will develop a “gravid spot” on the abdomen.
Do goats clitoris?
majora is homologous to the scrotum in males, and it is the visible external portion of the female tract. The clitoris is located in the lower portion of the vulva. It is the excitatory organ of a doe’s reproductive tract.
Do fishes have periods?
Fish do not have periods. They have internal sexual organs and ovaries that produce unfertilized eggs once a year. When the eggs have matured, the female will eject them into the water for external fertilization by the male. This process, called spawning, makes a menstrual cycle in fish unnecessary.
What is the mother fish called?
What is a female fish called? A female fish does not have a specific name, male and female fish are both just called fish. However, around 500 species of fish are able to change their gender during their later life after birth. A species of fish that can change its gender is called a hermaphrodite.
How can you tell if a fish is a boy or a girl?
You can determine the sex of your fish by inspecting its gonads (reproductive organs), which are located towards the top of the gut cavity. Mature female fish will have orange ovaries and male fish will have white testes (see photos above).
Do fish eat their babies?
Yet scientists have repeatedly observed males eating some of the carefully-provided for eggs. Filial cannibalism often occurs in fish species in which males care for the eggs or young.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
Can goldfish get pregnant by themselves?
No. Goldfish cannot actually be pregnant because they cannot carry live babies inside of their bodies. They release unfertilized eggs into the water where the male fertilizes them and they wait to hatch.
Are my goldfish trying to mate?

Do goldfish eat their babies?
A goldfish will likely eat their babies because they end up producing hundreds of eggs when they mate. Goldfish don’t have any paternal instincts, so they don’t recognize their babies. This means they may eat their babies if they are in the same tank.
Why is my goldfish so fat?
Overfeeding – Sometimes a fish may become fat or swollen as a result of his diet. Often, overfeeding or the wrong types of food can cause constipation and other digestive issues. You can try to feed your fish less or healthier types of food, which varies depending on the species of fish.
Do male fish lay eggs?
The female lays the eggs, after which the male fertilizes them. The male fish keeps the eggs inside its mouth until they hatch. This protects the eggs from being eaten up by sea animals. What is a fish?
Do all female fish lay eggs?
Not all fish produce eggs
A few species of fish do not lay eggs but produce live babies, called fry. Some live bearers breed easily in home aquariums, including guppies, swordtail, Endlers fish, mollies, and platies.
Do fish lay unfertilized eggs?
Most fish, including trout and salmon, lay unfertilized eggs. The eggs are fertilized externally by the male. Fish typically release hundred or even millions of eggs, which increases the chance that a few offspring will survive into adulthood.
How do goldfish mate?
Goldfish mate by chasing each other until the female goldfish releases her eggs. The male goldfish then releases his “milt”, which fertilizes the eggs. What is this? Assuming the eggs don’t get eaten, baby goldfish will hatch around a week later.
How do mermaids have babies?
How are mermaids born? Once again, assuming mermaids reproduce the way fish do, mermaid babies would be born by hatching from eggs. Though it is possible for mermaids to get pregnant and give live birth like dolphins.
Do cows and horses have vaginas?
There are two ovaries, two oviducts, two uterine horns, a uterine body, cervix, vagina and vulva.
Can human sperm fertilize a goat?
No, your sperm isn’t compatible with the eggs of a goat or another animal. It’s like attempting to put two different puzzle pieces together – they won’t fit! Female eggs have receptors, and your sperm will not fertilize the eggs of another animal.
Can sharks smell my period?
A shark’s sense of smell is powerful – it allows them to find prey from hundreds of yards away. Menstrual blood in the water could be detected by a shark, just like any urine or other bodily fluids. However, there is no positive evidence that menstruation is a factor in shark attacks.
Do dogs get periods?
Dogs typically go into heat on average every six months, but this varies especially in the beginning. It can take some dogs around 18 to 24 months to develop a regular cycle. Small dogs usually go into heat more often — as much as three to four times a year.
What is a group of fish called?
When fish, shrimp or other aquatic creatures swim together in a loose cluster, this is typically called a shoal. It can be a mix of different species. A school is a group of the same fish species swimming together in synchrony; turning, twisting and forming sweeping, glinting shapes in the water.
What is the name of a female catfish?
A female catfish is called a fish, as is the male, because there are no other names for the female or male of this species. Learn which is a female catfish and which is male through mating behavior and physical clues unique to each catfish species. Plecos are one of the most popular aquarium catfish.
Do fishes fart?
Biologists have linked a mysterious, underwater farting sound to bubbles coming out of a herring’s anus. No fish had been known to emit sound from its anus nor to be capable of producing such a high-pitched noise.
Do monkeys have periods?
Apart from humans, menstruation has only been observed in other primates, e.g. Old World Monkeys and apes (inhabiting mainly Africa and Asia), 3-5 species of bats, and the elephant shrew.

Can you drown a fish?
Because oxygen levels in the water aren’t anywhere close to what they are in the air, fish need to move a lot of water to stay alive. The large surface area of the gills helps them collect as much oxygen as possible. If they’re unable to do this, they can drown (although we know it’s technically more like suffocating).
Do fish get thirsty?
They don’t ever get thirsty. Marine fish are what’s called hypertonic to the seawater. So essentially, they lose water through their gills to the seawater. The seawater is saltier than their blood.
Do fish go pee?
A lot of fish get rid of the pee through an tiny opening, called a pore, that’s near their rear ends—and in some fish, waste also goes out through the skin or the gills. When a fish pees in a coral reef, the corals wave their tentacles around like tiny arms to grab nutrients from the pee and absorb them.
Why are goldfish white?
Why Is My Goldfish Turning White? Goldfish have pigment in their skin that reacts to light. When their skin is deprived of light or they have less exposure, this impacts their skin. Over time, they can lose their color and turn white.
Can fish change sexes?
Researchers have identified more than 500 fish species that regularly change sex as adults. Clown fish begin life as males, then change into females, and kobudai do the opposite. Some species, including gobies, can change sex back and forth. The transformation may be triggered by age, size, or social status.
Why do fish eat their poop?
Some animals, such as rabbits, may eat faeces as a “2nd round” of nutrition and it’s entirely possible that a fish might ingest some poop that they mistook for other foods – but this isn’t necessary for their nutrition and isn’t likely to help out with your tank health (we’ll talk more about this soon).
Why do female fish eat their eggs?
Sometimes, fish eat their own eggs to compensate for their own lack of food and energy. While angelfish do remove some eggs during the process of cleaning and caring for them, some angelfish may eat all eggs as a response to certain stress factors.
What color is fish poop?
For instance, if you feed your fish flake food then their fish will come out as brown or red. However, if they eat shrimp or meat then their poop will come out pink and if they eat peas or algae then their fish will turn green.
Can goldfish see you?
Eyesight is a highly developed sense in goldfish. In fact, they have vision superior to that of a human in some respects. We humans are air based creatures and evolution has graced us with seeing long distances with excellent resolution of up to a mile. The goldfish sees clearly only for about 15 feet.
Will my goldfish lay eggs?
Do goldfish lay eggs? Yes, they do! And female goldfish don’t just lay one or two goldfish eggs at a time… It’s one of our favorite goldfish facts that a female goldfish can lay several thousand goldfish eggs in one spawning!
Does a goldfish sleep?
Unlike people, goldfish do not lie down when they sleep. Rather, they become less active, staying in one place and moving slowly to keep themselves stable. They look like they are hovering in the tank or pond, usually low in the water, an inch or so off the bottom, with their heads pointed slightly downward.
How do you tell if my fish are mating?
Mating Ritual
Signs that your goldfish are ready to mate include white spots along the gills of the males, and the female will become fatter and more rounded. The male will then chase the female around the tank to encourage her to release her eggs.
Are goldfish asexual?
Most goldfish breed in captivity, particularly in pond settings. Breeding usually happens after a significant temperature change, often in spring. Males chase gravid female goldfish (females carrying eggs), and prompt them to release their eggs by bumping and nudging them.
How old is a 1 inch goldfish?
Age | Slim-Bodied Goldfish | Fancy Goldfish |
---|---|---|
1 month | 0.9 inches | 0.9 inches |
6 months | 2 inches | 1.5 inches |
12 months | 3.25 inches | 2.75 inches |

Are goldfish born black?
All metallic Goldfish start off silver gray, turn black, then slowly fade to a light yellow before their colour deepens to orange or red, sometimes with patches of white. Metallic Goldfish can start changing colour within 3 months of hatching. Goldfish change colour at different rates.
Do goldfish have genders?
Male goldfish and female goldfish have visible differences in their pectoral, or front, fins. These differences can be difficult to spot if you have particularly active goldfish. Males have longer, narrower fins than females, while female goldfish tend to have thicker, shorter fins.
Will goldfish lay eggs without a male?
Goldfish are egg-laying animals. They have the ability to reproduce asexually without mating. Therefore, they are technically both females and males.
Can goldfish explode?
Dropsy is an extremely serious and often fatal condition affecting goldfish. If you notice your goldfish looking fat, swollen or “about to explode” then the problem is probably dropsy.
Can goldfish lose weight?
Goldfish are naturally ravenous creatures and will eat just about anything if given the chance. So a goldfish refusing to eat or showing noticeable signs of weight loss should be a warning sign that there’s a problem that needs closer looking into.
How old do goldfish live?
Goldfish have a lifespan averaging about 10-15 years, with some varieties living up to 30 years when provided with proper care. Unfortunately, many goldfish do not reach their lifespan potential due to inadequate housing conditions. Housing needs to meet both their behavioural and physiological needs.
How do fish get pregnant?
In most cases, the female drops eggs in the water which are immediately fertilized by sperm from the male. Another way is for fertilization to occur within the females body before she drops them into the water. With the third and final method, the female retains the eggs within her body and the young are born alive.
Are dolphins lay eggs?
Other characteristics of dolphins that make them mammals rather than fish are that they give birth to live young rather than laying eggs and they feed their young with milk.
Does frog lay egg?
Most frogs and toads begin life as eggs floating in the water. A female may release up to 30,000 eggs at once. Each species of toad and frog lays eggs at different times. Some lay eggs as early as March.
