Fish anatomy is primarily governed by the physical characteristics of water, which is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does.
Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. Fish anatomy is partially shaped by the physical characteristics of water, the medium in which fish live.
