How are fish and mammals the same?

Fish are cold-blooded, have scales over their skin, have laterally flattened bodied, are finned, require immersion in water to survive, and reproduce by laying eggs.

Mammals are warm-blooded,have hair over their skin, are mostly four-limbed in the body forms, breath air but some live in water, and reproduce by carrying their young inside the female body until they are born alive.

Most mammals care for their young, while most fish do not.

How do you know if salmon is bad?

If it smells bad, it is bad. The fishmonger will rarely try to peddle Salmon as fresh caught to a regular customer for fear of losing repeat business. Check the eye of the fish for clarity, cloudiness indicates poor quality. In the supermarket where things are pre-packaged look for a cut that appears silky smooth like a gemstone and has that type of color. In many countries Food Safety laws require labeling if color is added so the customer should always read the label for full disclosure. Do not hesitate to ask the market manager for a smell sample even if you are making a small purchase. If the Fish Smells Fishy reject it. If, god forbid, the question refers to a canned product that smells even slightly off, then toss it and order in a pizza. Trust your nose because if it smells bad, it is.

How does the salmon attract its prey?

Sockeye salmon have very short lives. They have many different behaviors that help them survive, such as going around in schools, where they trade places so they can all eat and avoid predators, taking turns at the safer places and the places with the most food. They also take the schools to different places depending on the time of day to avoid predators and to find the best food. They can live up to 3 years in freshwater before they migrate to the ocean. Then they spend 1-4 years there, and come back to freshwater to spawn. After spawning, they die.

How many eggs can Siamese fighting fish lay at one time?

The number of eggs a fish lays at a time varies widely among different species and sizes of fish. Some fish lay only a few; others lay millions. Usually this has something to do with how the fish care for their eggs. With the species that simply leave their eggs' survival to chance and just swim away, more eggs are produced. If a species sticks around and looks after the eggs until they hatch, and even watches over the baby fish, usually less eggs are laid.

For example, Cod lay up to 9 million eggs, but these are left to drift where they will, and so many don't survive even to hatch. Herrings, which lay around 50,000 eggs, also abandon them, but the eggs stick to the bottom and are less likely to be eaten by predators.

Species such as bass, salmon, some sticklebacks, and trout stay and watch over their eggs, which often sink and stick to the bottom like herring eggs. But these species lay far fewer eggs than herrings, because the extra protection gives the eggs much better chance of survival.

If you had a certain category or species of fish in mind, asking more specifically about it would result in a better answer.

Anyway, I hope this helped.
