To cover the greatest horizontal distance, the animal should jump at a 45 degree angle. The animal can do nothing in mid-flight to extend its jump. The zero g-roll has the same shape as the dolphin bows, called a parabola. The dolphins will also feel weightless during their bows. On the zero g-roll, the weightlessness lasts for several seconds.
Fish often have the same density as water and neither sink nor float.
Blubber is less dense than water, and a large amount of blubber would insure floating. Air trapped in feathers or air in the swim bladder of a fish also help in floating. The boats on the water rides float much higher in the water than do the animals. All Rights Reserved.
