Question

Whales have ______ that help in swimming.​

Answer 1

Answer:

Whales swim forward by flexing their tails up and down, instead of side to side as with most fish. To change direction, they move their flippers, similar to the way an airplane steers (read How Sharks Work for details). The dorsal fins, if present, serve to stabilize the whale's body as it swims.
