Question

dolphin movement what​

Answer 1

Answer:

Bottlenose dolphins sometimes "porpoise" at the surface; they swim fast enough to break free of the water, flying up and out and then back under in one continuous movement, which they generally repeat. Porpoising uses less energy than swimming fast at the surface.

Answer 2

Answer:

"Dolphins generate a lift force that is directed forward, on both the upstroke and downstroke." This produces the thrust that pushes the dolphin through the water. The flukes are also flexible, which is key to enabling the dolphin to maintain a highly efficient way of swimming over a broad range of speeds.
