A bird flies. If it was not semetrical, it would fly crooked. If birds flew crooked, there would be a bunch of birds flying around in circles. Sponges do not fly or even move, so they do not need to be semetrical.
The only bird that can fly backwards is the humming bird'
Yes, birds with long legs can fly. The only bird with long legs that cant fly is the Ostrich. The only problem is that because of their long legs they are so used to walking, so they don't fly as well as other birds.
