Like dolphins can swim

Sang David Bowie in his song Heroes. And he is right. Throughout the centuries, seamen and dolphins are a good match. The very first sailors wrote about them, and their apparently neverending playing in the bow waves of passing vessels. Fast or slow, all vessels seem to attract them. Commercial vessels, and even fast navy ships are no match for them. There are no better swimmers, and if so, there are no friendlier looking swimmers than dolphins.
