Why do many animals evolve into axisymmetric shapes and asymmetrical internal organs?

Symmetrical shape is generally for the convenience of balance, and symmetrical shape can better maintain the balance between gravity field and fluid resistance. Internal evolution is more like an engineer's design of a car, which needs to consider the failure rate, material consumption, overall efficiency and so on brought by different designs, and is the result of comprehensive consideration. Your preference for symmetry may be due to your lack of careful observation of nature, because there is almost no absolute symmetry in nature. If you read more, you will naturally find the universality and beauty of asymmetry, and you will not be so persistent about symmetry.
