How is fish made?
by
The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage (cartilaginous fish) or bone (bony fish).
“Fish do feel pain. It’s likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
When did fish came to earth?
The first fish appeared around 530 million years ago and then underwent a long period of evolution so that, today, they are by far the most diverse group of vertebrates.
Young fish are generally considered fry during their first few months (during their first few months to just less than one year in some species). Juvenile: The time fish spend developing from fry into reproductively mature adults varies among species. Most fish do not survive to become adults.

How fish are made story?
HOW FISH IS MADE is a short narrative-driven experience about talking to fish and making choices. You are a sardine in a machine, but is life that simple? This place imposes on you and your fellow fish a prophetic choice. Will you help them, or lead them astray?
How can you tell how long a fish is?
Total Length is measured from the most forward point of the head, with the mouth closed, to the farthest tip of the tail with the tail compressed or squeezed, while the fish is lying on its side.
How old do fish get?
The majority of common tropical fish live for an average of three to five years, while goldfish are among those living the longest, potentially up to 20 years. Koi, who are cousins of the goldfish, can live up to 40 years.
What are the 4 stages of a fish?
The life cycle of marine fishes is comprised of four developmental stages: egg (or embryonic), larval (yolk-sac and non-yolk-sac), juvenile and adult.
How long is pregnancy for fish?
Fish pregnancy can last anywhere from 3 weeks to 3.5 years depending on the species. Fish pregnancies usually last between 3 weeks and 10 months. This huge range is due to the differences between various fish species. Aquarium fish like goldfish or guppies are at the lower end of the spectrum.
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.
How are fish born?
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.
How do fish got pregnant?
Most fish spawn by releasing eggs and sperm directly into the water column to achieve fertilization. This can be done on a one-on-one basis or in a group. Many salmonid species take the more intimate and monogamous approach. One of the benefits of this strategy is that only one male’s sperm fertilizes a batch of eggs.
How do fish get sperm?
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. Sometimes the pelvic fins are modified to help transmit the milt to the eggs at the female’s vent or on the substrate where the female has placed them.
Can boy fish get pregnant?
Pipefishes and seahorses are the only species to which the term male pregnancy has been applied. Although paternal care is fairly common in the animal world, few if any species have taken it to the outrageous extremes seen in Syngnathidae.
Male seahorses not only become pregnant and give birth, but do so in ways that take different forms, which make them unique research subjects to understand the evolution of pregnancy, according to Dr Olivia Roth from the Helmholtz Centre for Ocean Research Kiel (GEOMAR) in Germany.
How do boys get pregnant?
People who are born male and living as men cannot get pregnant. A transgender man or nonbinary person may be able to, however. It is only possible for a person to be pregnant if they have a uterus.
