Answer #1 by Poke bro With their tail. Answer #2 by Ginezumi A narwhal [Monodon monoceros] swims with the upturned tips of its flippers, its tusk and head, and its tail. The flipper tips and the tail help the narwhal steer. The flipper tips also help the narwhal stop. The tusk and head help the narwhal to move by echolocation. The tusk detects differences in water temperature, salinity and pressure that may affect swimming conditions. The mouth emits sounds that come back as sound waves. The sound waves are processed by the head, and possibly also by the tusks, to swim around upcoming obstacles in the sea.
