It is perhaps difficult to accept that if this was a whale, that there could have been only one of this kind in this large oceanic expanse, yet in spite of comprehensive, careful monitoring year-round, only one call with these characteristics has been found anywhere, and there has been only one source each season.
(Although this story may have a happier ending – some scientists now believe they've picked up similar signals, meaning the whale might not be alone after all.)
