article_snippet.sent: Scientists may have captured Song.
article_snippet.sent: Song can’t be identified and doesn’t fit the pattern of noise generated by the few known species of beaked whale, raising hopes that Song could be coming from a completely new species.
article_snippet.sent: Experts are sure the noise isn’t made by Arnoux's beaked whales or Cuvier's beaked whales (stock image), because the signal doesn’t match .
article_snippet.sent: But the song belong to a strap-toothed whale, a southern bottlenosed whale or a Gray’s beaked whale (pictured), according to the study, despite the sound being the wrong frequency for a Gray’s beaked whale .
article_snippet.sent: Whale sounds are used by whales for different kinds of communication.
article_snippet.sent: The word 'song' is used to describe the pattern of regular and predictable sounds made by some species of whales.
article_snippet.sent: While the complex sounds of a Gray’s beaked whale and some blue whales are believed to be primarily used in sexual selection, some blue whales use simpler sounds all year round to communicate.
article_snippet.sent: Whales occupying the same geographical areas, which can be vast, tend to sing similar songs with only small variations.
article_snippet.sent: Male humpback whales have been described as 'inveterate composers' of songs and experts have said that Male humpback whales songs are similar to human music in many ways.
article_snippet.sent: Experts are sure the noise isn’t made by Arnoux's beaked whales or Cuvier's beaked whales, because the signal doesn’t match Arnoux's beaked whales or Cuvier's beaked whales songs.
article_snippet.sent: But the signal could belong to a strap-toothed whale, a southern bottlenosed whale or a Gray’s beaked whale, according to the study, published in the Journal of Marine Mammal Science.
article_snippet.sent: It is very rare for strap-toothed wakes to be sighted as far south as the noises have been heard, while the noise is the wrong frequency for a Gray’s beaked whale, leaving the southern bottlenosed whale as the most likely match.
article_snippet.sent: But again there’s a problem, because the whale’s relative, the northern bottlenose whale, makes very different calls, leading experts to think that the southern species probably vocalises in a similar way
article_snippet.sent: Because frequency is usually linked to a whale’s size, there is a theory that the Antarctic BW29 song may be made by a southern bottlenose whale, while the higher pitched Antarctic BW37 song could be made by a smaller Gray’s beaked whale.
article_snippet.sent: There’s also a chance that new species of whale could sing at different frequencies, but this ability would be unique among beaked whale species.
highlights_snippet.sent: Song doesn't fit the pattern of noise made by beaked whales .
  
highlights_snippet.sent: Song could hint at a new species or could be made by a southern bottlenosed whale, although experts have experts reservations .
