Biology/How dense are fishes?


How dense are fish? Are they as dense as humans at around 1 gram per cubic centimeter?

Hi mika
The density of fishes is about the same as that of humans or the water is swims in. Salt water has a greater density then 1 and so the fish has a density  the same. Most fishes have a swim bladder that they use to change the density so they can change levels
