Cummings and Philippi, who worked on the Navy's marine mammal research program, found that in the right whale, "Low frequency sounds occurred in similar stanzas lasting 11 to 14 minutes...These phonetic components...were so orderly that listeners could predict the appearance of the next type of signal." Carl Sagan noticed that the same phenomenon occurs in the humpback whale...
