Hi all,
in the following context:

"For most killer whales it's one continuous journey, they spend nearly all of their time searching for prey and to avoid losing the element of surprise – don't hang around in one area too long, they can easily clock up a hundred swimming miles in one day ".

Does "swimming mile" correspond to "nautical mile"? I googled "swimming mile" but couldn't find it.

Thanks in advance.

    It means that the amount of swimming they do in one day is equivalent to swimming from point A to point B where the distance between point A and point B is 100 miles. So it's a measure of effort rather than distance.
