The density of the liquid water is rho = 1,000 kg/m3 or 1,0 g/cm3.
SI standard for density rho = mass m / volume V in kg/m3.
A fish should have a very similar density to the water it swims in. Archimedes' principle states that the buoyant force on an object is equal to the weight of the water it displaces. The total vertical force on a fish is that of gravity, the buoyant force, and any reaction force generated by swimming. If the fish were much denser than water or saltwater, as the case may be, the weight of the displaced water would be much less than the fish's weight, and the fish would sink. If the fish were much less dense, then the fish would float to the surface. To keep at a desired depth, perhaps with a little help from swimming, the fish should be about as dense as the water it swims in.
Many fish have a swim bladder, also called a "gas bladder", which fills with a gas, usually oxygen, and which helps regulate the fish's average density. The rest of the fish then is a bit denser on average than water.

However the volume changes. The water is the most dense at 3.98 degrees C.

What does gravity spicific mean?
Perhaps you mean "specific gravity". That refers to an object's density, compared to the density of a reference subtance (usually water). For example, if iron has 8 times the density of water, then its specific gravity is said to be 8.
Why do ships sink more in fresh water than in salt water in respect to freeboard?
It is because the fresh water has less density compared to that of salt water.
What is the density of water vapor in relation to the air's density?
I sugest you look up "steam tables". Since convection currents are caused solely by diferences in density ... yes, it is assumed that tempreture diferences CAUSED the density gradiant - but that is not always true.
An object less dense than water will in water?
The "average" density of the object must be less than that of the water displaced.
How is the density of a fish controlled?
Fish control their density with a gas-filled organ called a swim bladder. The average density of a particular fish's tissues, not including gas in the , is 1070 kg/m^3.
What is styrofoam density compared to water?
The density of styrofoam is lower: about 0.028 to 0.045 times that of water.
Does Alcohol have a high density?
Well that depends, do you think 0.79 grams is high? Compared to water, which has a density of 1.0 grams.. so does alcohol have a high density compared to water? No. :P
What is the density method?
mass / volume = density relative density is that compared to water ( 1g / cm3)
How do fish use density in order to move in the water?
Fish use density in order to move in the water since they do not have lungs. When the density of water keeps changing, fish use it to move and thereby using less energy.
What is compared to water that allows ice to float?
Density.
What is the effect of sugar compared to water on density?
Sugar has a greater density than water. This is obvious from the fact that it sinks in water. If you add sugar to water, the water's density increases.
What is the method?
mass / volume = density relative density is that compared to water ( 1g / cm3)
A piece of ice floats on water. what does this tell you about the density of ice compared to the density of water?
It tells you that the ice is less dense than the water.
What defines the ratio of the density of a substance compared to the density of water at 4 celsius?
specific gravity
What is the property of that makes something sink or float?
More or less density of the material compared to the density of the water.
What is the density of water in the solid state compared to that in the gas state?
Much higher.
What does density tell you about salt water?
The density of a salt water solution compared against the densities of "pure" water and salt provides an approximate value of the ratio of water to salt in the mixture.
