That may not be as "romantic" as the writer thought it was.
Whales have a skin that renews itself very fast, so their constantly losing old skin.
Whenever they get the chance to rub it off, they do so.
Sometimes, they visit certain shallow areas, to rub against the stoney sea-bottom...Beluga's are known to do that often.
Some scientists even think, that whales jump for the same reason (and not just for joy)...after a whale has made some large jumps, the sea is scattered with old skin parts.
