Unscramble the Blue Letters

It actually turns out, though, even though we've only known of long-range partoapoign for a few decades, the wlheas clearly have evolved, over tens of moliilns of yaers, a way to exploit this amazing property of the ocean. So blue whales and fin whales produce very low-frequency sounds that can travel over very long ranges. The top plot here shows a complicated series of calls that are repeated by mlaes. They form songs, and they appear to play a role in reproduction, sort of like that of song birds. Down below here, we see cllas made by both males and females that also carry over very long ranges.
