Males are also known for performing very song-like sounds that are more regularly used during mating season to try to impress a female humpback.
While you may not be familiar with the sounds made underwater by the humpback whales, the sounds you are able to hear are the ones created by surface behaviour. The sound this creates can be heard above and below the water. Lobtailing is when a humpback whale will hold their tail above the water and swing it around before slapping it on top of the surface of the sea. This is an action that also creates a sound that is heard, once again, both above and below the ocean.
While research is still underway to understand the reasoning of the surface behaviour sounds, it is clear that these sounds do signify something important to the whales.
It is believed that these slapping sounds may be a vital way of one whale communicating a warning to the rest of the pod. Looking for more things to do and see? Pop into one of the region's Accredited Visitor Information Centres.

James Nestor, an avid ocean-adventurer, author, and speaker, relates the experience of swimming alongside a pod of sperm whales and feeling the clicks vibrate inside his body. Loud sounds carry even more punch when traveling through water, since the water is much denser than air. Sperm whale clicks are far more amplified in the ocean than they would be on land. Watch this short video for a glimpse into the world of sperm whales, complete with the sound of their clicks.
Most of the toothed whales use echolocation to find their prey, often in the pitch black of the deep ocean. Echolocation consists of a series of clicks that the animal aims forward from its snout, with the ability to receive even the faintest of echoes as the sound waves bounce off objects, plants and animals and return to the originator of the clicks.
According to the Smithsonian Museum, sperm whales can use echolocation to detect a small squid less than a foot long more than a mile away, and schools of squid from even farther away. We can see how the whale uses echolocation like an acoustic flashlight. Whales and dolphins have ears, but their ear canals do not open to the outside. Whales and dolphins generally hear sounds through special structures in their jawbones, with fatty lobes near the jaw being connected to the inner ear.
Take the bottlenose dolphin, for example. Scientists have found that each bottlenose dolphin develops a its own distinctive signature whistle Tyack, Each unique whistle appears to serve as a means of individual identification.
Just as we refer to one another by name, each dolphin identifies itself by using its own unique whistle and copying the whistles of other individuals, as if calling them by name. Dolphins will often whistle to another dolphin, with the other dolphin moving toward the whistler. Dolphins also whistle when separated from their family group. If they become separated, a young calf and its mother will whistle repeatedly until reunited. Not only do these dolphins call each other by name, they can remember the whistles of other dolphins after 20 years of separation.
Research from the University of Chicago shows that dolphins have the longest memory of any species other than humans that we know about. In some species, notably the humpback whale, males can repeat long, complicated songs. The standard hypothesis is that these songs appear to play a role in reproduction, by helping to attract mates and by sending signals to potential rivals. The latest science, however, is not so clear cut.
Some scientists, Dr. Jim Darling, Whale Trust, for example, postulate that whales sing to convince other whales that they have certain characteristics that they want project. Take the killer whale Orcinus orca , for example. There are certain clans of orca known as transients that specialize in hunting marine mammals, including seals, sea lions, and other whales. In marked contrast to the hunting style of most toothed whales that hunt using echolocation, including clans of fish-eating orcas, the transient orcas have developed the ability to hunt cooperatively in silence.
Silent hunting allows these killer whales to sneak up and ambush their prey, but it also means that they must be using visual signals to coordinate the hunt. Since whales and dolphins live in an acoustic environment with greater dependence on sound processing, this is reflected in the structure of the brain.
In a cetacean brain the neural area devoted to visual imaging is only about one-tenth the comparative size of that in the human brain. Conversely, the area of the brain devoted to acoustical imaging is about 10 times as large.
Whales and primates both show dramatic growth in the same two regions of the brain: the cerebellum and neocortex. Both regions are important for the higher cognitive functions involved in communication. After analyzing the brains of both toothed and baleen whales, the Mount Sinai researchers found concentrations of spindle cells associated with higher cognitive functions. In humans, these types of brain cells are involved with self-awareness, a sense of compassion, and use of language.
One of the amazing things is that whales evolved these highly specialized neurons millions of years before we humans did! This is a good example of parallel evolution, whereby physical traits that perform a similar function evolve independently in different species. Another good example of parallel evolution is the eye of the octopus, with the same complicated structure as the human eye.
Smart Suckers! Yes — these amazing animals have 3 hearts and 9 brains! Take killer whales, for example. Even though the clans can share the same waters, their vocalizations are as different as English and Greek.
The three main types of sounds made by whales are clicks, whistles, and pulsed calls. Clicks are believed to be for navigation and identifying physical surroundings. When the sound waves bounce off of an object, they return to the whale, allowing the whale to identify the shape of the object. Clicks can even help to differentiate between friendly creatures and predators.
