How do fishes move effectively through such a dense medium as water?

Expert Solution
To determine

The way in which fishes move through such a dense medium like water.

Explanation of Solution

Seawater appears to be a perfect habitat; however, dwelling in it presents difficulties as well. The density of water is almost 800 times greater than air and its viscosity is around 100 times large than air. This would effectively hinder the motion at low speeds. The fishes are able to cut through this medium, despite their density and viscosity.

Normally, the propulsive efforts are made more effective by the streamlined bodies of active fish. The anterior area, body outline, and surface texture determine the resistance of a fish to movement, or drag. The increase in speed increases the drag geometrically. The fast swimmers among the fishes might be largely modified for reducing the decelerating effects of the denser and comparatively sticky medium in which they reside...
