Like other whales, the male fin whale has been observed to make long, loud, low-frequency sounds. [19]Most sounds are frequency-modulated (FM) down-swept infrasonic pulses from 16 to 40 hertz frequency (the range of sounds that most humans can hear falls between 20 hertz and 20 kilohertz).
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 ...
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]
It is one of Earth's most haunting sounds - the "singing" of baleen whales like the humpback, heard over vast distances in the watery realm. Baleen whales - a group that includes the blue whale ...
Blue whales produce some of the loudest and lowest frequency vocalizations in the animal kingdom, [26] and their inner ears appear well adapted for detecting low-frequency sounds. [100] The fundamental frequency for blue whale vocalizations ranges from 8 to 25 Hz. [101] Blue whale songs vary between populations. [102]
Before extensive research on whale vocalizations was completed, the low-frequency pulses emitted by some species of whales were often not correctly attributed to them. Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...
And that's true, but this is a blue whale, which is the largest animal to ever live on Earth. Blue whales can grow up to 100 feet long and weigh about 200 tons — that makes them bigger than ...
An underwater photographer who got up close and personal with a massive blue whale says the experience left him feeling awestruck — and incredibly small. Stunning photo shows diver's close ...
