There are many interesting parts in a goldfish. There are lots of fins in the gold fish. The anal fin is the fin just before the tail, and the tail is called the caudal fin too. Another one is the dorsal fin which is the single fin on top of the back, the pectoral fin which is the first forward pair of wings, and the pelvic fins which are the second ventral pair of wings. The top of the head is called the cranial. The scale is the skin of the goldfish. The fish has eyes, mouth, and nostrils also.
Goldfish live in environments which oxygen is in relatively found than us. The density of water makes it difficult for us to move fluid back in forth in the respiratory organs like we do with our lungs. That is why goldfish and other aquatic animals have special adaptations to solve these types of problems. Gills are the respiratory organ of most aquatic animals that breathe water to obtain oxygen, consisting of a filamentous structure of vascular membranes across which dissolved gases are exchanged. Instead of pumping water into and out, the animals pump water in one opening out to another making something like a stream in the organ but the animals don't use their energy to make it stop flowing then starting it on the opposite direction. Then, to make more gasses between the blood and water, it has an exchange system that exchanges gas.

Every animal has adapted over time.
goldfish are not always one color because they have different species. Also, goldfish can change colors over time. They won't always be gold or maybe they won't always be white or whatever color your goldfish is.
Any breed of Goldfish can eat it but onlygoldfish.A female goldfish can lay many thousands of eggs every springtime for up to and over 40 years or so. She can also grow to over 20 inches long in this time.
no answer avalible
because they have adapted to it over time
over time it will evolve depending on its environment
A palaeoeconomy is a term used for the way economy has adapted over time.
Not a goldfish anymore.
The goldfish did not evolve naturally and in nature. Goldfish did however evolve with the assistance of man who selectively bred and developed them to have the different colours and shapes they now have.
No Goldfish do not normally die after they spawn. Goldfish can live and spawn regularly for over 50 Years.
In late spring of early summer is the best time to breed goldfish.
there are three basic breeds: fantail goldfish, comet goldfish, and common goldfish. if you are getting goldfish for the first time, i would recommend common goldfish as they need the least care.
