In theory, no. Goldfish are aquatic animals meaning they live in the water. They cannot be out of water for long periods of time without dieing due to lack of water. With that said, Goldfish cannot fly through air. If you threw a goldfish in air itd might be considered "flying" but in reality its most likely to die. Goldfish do not have the natural ability and talent to fly through air. If you built a tank that can support water and fish in the air and fly it then they can fly using that device, as we fly using a helicopter,jet,plane, etc.
A fly can live without an abdomen due to the anatomy of the fly. A fly feeds constantly and passes feces regularly.
No, the air is what allows for lift. The only way an airplane can "fly" without air is if the downward force of gravity didn't exist.
A raven can fly for long distances without landing, sometimes up to 40 miles without stopping.
Research suggests that flies can stay in the air for about one to two miles without rest. The average speed of a fly is about five miles per hour.
i think it takes a long time for a hot air balloon to fly
No... planes stay airborne because the air flowing on the underside of the wing is moving faster than the air flowing over the top of the wing. Without air movements - the plane cannot fly.
Hot air balloons can pick up and fly from just about anywhere. As long as the surface is flat a hot air balloon can fly from it.
As long as they live/work ofcourse.
they can live to be at least 6 weeks on its own
A crane fly lives just long enough to mate...a few days
They wouldn't be able to fly there at all, without air.
