Humans and many other animals have stomachs to digest food, but goldfish don’t. Instead of a stomach, they have different parts of their intestines that have to break down food into simpler sugars and acids.
Goldfish have a unique digestive system that allows them to eat a wide variety of foods. They also have the ability to absorb nutrients from their environment, which is why they are able to survive in the harsh environment of the deep sea.

Do the fish has stomach?
The mouth, teeth and gill rakers are just some of the structural components of a fish’s digestive system. Some components are not present in all fish species. The mouth is the largest organ in the body and is responsible for swallowing, chewing, swallowing food and swallowing water. It is also the most important organ for digestion and absorption of nutrients.
The mouth also plays an important role in digestion of fats, proteins, carbohydrates, vitamins, minerals, amino acids and vitamins A, B, C, D, E, K, M, N, P, Q, R, S, T, U, V, W, X, Y, Z, and Zn.
In addition, it is a major source of bile acids, lipids, cholesterol, triglycerides, sodium, potassium, calcium, magnesium, phosphorus, iron, manganese, copper, zinc, chromium, cobalt, boron, nickel, molybdenum, selenium and copper. Taste buds are located at the back of the tongue and are used to detect the taste of different foods.
What animal has no stomach?
Around 450 million years ago, the stomach was the first part of the gut to evolve. “It’s the only animal that doesn’t have a stomach,” said study co-author and University of California, Berkeley, paleontologist Mark Norell, who was not involved with the study.
“It has a very small intestine, which is very different from the stomach of any other animal. This animal has very little fat and very few muscle fibers.” [See Photos of Platypuses and Other Dinosaurs] Platyphlops, a new species of plesiosaur discovered in China.

Why does my goldfish have a big belly?
Grossly Swollen Belly This happens as fluid accumulates in the tissues and cavities of the abdomen to create the swelling of the area. The kidneys and spleen are swollen because they are shutting down and can’t eliminate the water build-up from the body. Diarrhea This is a common symptom of dehydration.
It can be caused by a number of things, such as not drinking enough water, not eating enough food, or not getting enough exercise. If you have diarrhea, you may be dehydrated because your body doesn’t have enough fluids to keep you hydrated. You may also have an infection in your intestines that is causing the diarrhea.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. According to research, fish may be less active and less alert to danger. Some fish float in place, others wedge themselves into a secure spot in the mud or coral, and some even locate their food by smelling the water.
In the wild, fish are usually found in groups of two or three, but in captivity they can be as large as 20 or 30 individuals. They are also often fed a high-fat diet, which can cause them to lose weight.
Do goldfish have hearts?
The circulatory system of fish consists of a heart, blood and lungs. The lungs are the largest part of the fish’s body. They are filled with air, which is used to breathe. In addition to breathing, fish also use their fins and gills to move around in the water.
What do goldfish do for fun?
Goldfish like exploring their environment. Giving them wide spaces, a varied diet, and other goldfish to swim with helps them enjoy their daily lives. You can use food to interact with them once they are used to you. If you can hold food over one side of the tank, you can move it to the other side. This will cause the fish to eat the food on the side it is on.
You can also use a food dispenser to give them a variety of foods to choose from. When you are done feeding them, it’s time to put them to sleep. To do this, simply place them in a corner of their tank and close the lid. The fish will sleep for a few minutes and then wake up. When they do, they will be ready to play again.
Do fishes poop?
Well most of them will expel their feces through an anal vent (also called a cloaca), which is simply an opening for all wastes to leave the body. This also includes feces, urine, reproduction, and sometimes eggs or sperm. In the case of a female fish, she will use her anus to expel her eggs, which will then be deposited in the water column.
The eggs will hatch in a few days and the fish will continue to produce eggs until they are large enough to be released into the environment. Once released, the eggs can live for up to a year or more, depending on the species of fish and how long it takes for them to mature.
