there are other less helpful justifications. It's possible that the second whale was attempting to establish his superiority over a lesser male or that he was attempting to appear bigger and more physically fit in comparison. The first whale was often observed to assume a possib...
Humpback whalesongs comprise units that are the shortest audible sounds. A series of units make up a phrase. A series of words make up a theme, and finally, a series of themes make up the song. One song can last up to 30 minutes and may be repeated for up to 24 hours. Mind-boggli...
Thehumpback whalewas very nearly extinguished from the planet during the 18thand 19thcenturies due to humans hunting—prior research has suggested that population levels dropped to 10 percent of pre-hunting days. But over the past half-century, laws protecting them have boosted survival. Those that...

Humpback whales (Megaptera novaeangliae) are a cosmopolitan baleen whale species with geographically isolated lineages. Despite last sharing an ancestor ~ 2–3 million years ago, Atlantic and Pacific foraging populations share five call types. Whet
Humpback whale songs from the ASSO shared phrase types with all the breeding and migration route/mid-latitude feeding ground songs included in the comparative analyses (Ecuador, Chile, Brazil, South Africa, and Namibia). The comparison of phrase repertoires revealed a high overlap (> 80%) betw...
(as perceived by human observers) is effectively a single song on any given day, variety is only “eventual” across a singer’s lifespan. Furthermore, the core assumptions that led researchers to hypothesize that humpback whale songs function as reproductive displays are becoming increasingly ...
while humans tend to use small components such as words or short phrases when learning language41. This further parallels other structural similarities between humpback whale song and both bird song and human communication, such as the underlying small-world structure found in all three taxa which ...
