Their approximation points, virus and mechanical mines in the sea

Although the size is completely different, the shape is exactly the same, don't you think? I'm comparing corona virus and mechanical mine floating in the sea, the center is round and surface is covered with needle like protrusions. Both of them kills human being, the former naturally exists on Earth and the latter one is artificially fabricated, they are hated because of cheating attack and hostile purpose, before that they look bad. The situation is completely different from the former epidemic of SARS a few years ago, still now we are at a loss and seeking the way to escape from the disaster. We are not so tough to conquer and to overcome the invisible enemy.
