What animal can swim and fly?

Many species of animals can swim and fly. It must be remembered that the animal kingdom consists of many groups. These are insects, birds, animals, fish and others. Mostly birds fly. Many of them can swim. These are ducks, swans, geese and many others. They have swim bladders. For immersion under water, they free the bubbles from the air, since they cannot submerge with the inflated air bladder. These birds are capable of landing and taking off directly from the surface of the water. In the reservoir, they often look for food or thus hide from natural enemies.
