[7] [8] [9] Because the calls have also been recorded from blue whale trios from in a putative reproductive context, it has been recently suggested that this call has different functions. [10] The blue whale call recorded off Sri Lanka is a three‐unit phrase. The first unit is a pulsive call ranging 19.8 to 43.5 Hz, lasting 17.9 ± 5.2 s.
There are at least nine separate blue whale acoustic populations worldwide. [41] Over the last 50 years blue whales have changed the way they are singing. Calls are progressively getting lower in frequency. For example, the Australian pygmy blue whales are decreasing their mean call frequency rate at approximately 0.35 Hz/year. [42]
Blue whale calls recorded off Sri Lanka have a three-unit phrase. The first unit is a 19.8 to 43.5 Hz pulsive call, and is normally 17.9 ± 5.2 seconds long. The second unit is a 55.9 to 72.4 Hz FM upsweep that is 13.8 ± 1.1 seconds long. The final unit is 28.5 ± 1.6 seconds long with a tone of 108 to 104.7 Hz. [110]
A mega-pod of dolphins put on a special show when it appeared next to Evan Donadt's San Diego whale watching boat. While passengers were hoping to spot a blue whale during the height of the whale ...
Still, uncovering the scope of whales’ vocal exchanges is an important step toward linking whale calls to specific messages or social behaviors, the scientists reported May 7 in the journal ...
The blue whale is the largest animal on Earth and likely the largest animal ever to have lived. While this ocean mammoth is dubbed “blue,” its color is more a reflection of the water it swims ...
The 52-hertz whale, colloquially referred to as 52 Blue, is an individual whale of unidentified species that calls at the unusual frequency of 52 hertz. This pitch is at a higher frequency than that of the other whale species with migration patterns most closely resembling the 52-hertz whale's [ 1 ] – the blue whale (10 to 39 Hz) [ 2 ] and ...
