Ducks are strong swimmers and can typically swim for several miles without getting tired. They are adapted for water with webbed feet and waterproof feathers, allowing them to cover long distances in search of food or shelter.
It is believed that they can dive to a depth of 50 feet to capture prey and will swim under water for short distances when pursuing their prey.
This Is From The Smithsonian Narwhals have inspired myth and wonder but are still little known to science. "Narwhals are hopelessly hard to see, never come when you want them to, swimming far offshore and underwater the whole time," she says. "You think you'll catch a whale in three weeks, you probably won't. Whole field seasons go by and you don't even see a narwhal. There are so many disappointments.

Polar bears can swim for hundreds of miles without stopping as they have been spotted out at sea hundreds of miles awat from any ice or land.
A sighting of narwhal has occurred at about 85° North latitude, and they very rarely go south of 65°N.

they can swim as far as 50 km an hour and faster than a cheetah
It really depends on what kind of a swimmer you are. If you can swim really well, you can probably swim really far. If you can't swim at all, you won't swim very far. I hope this answers your question.
Narwhals have thus far been unable to be kept in captivity. For whatever reason, they die very shortly after capture. For this reason, no aquarium, no matter how large, will have narwhals. Not even Sea World.
