These sounds are known as whale songs.
Both male and female whales can vocalize but only the males produce these loud, long and complex melodies.
Unfortunately researchers don’t have a clear understanding of what these sounds mean and aren’t able to interpret what exactly is being communicated or said between the male and female whales.
They have however been able to point out some interesting facts and have come up with some information regarding the possible meaning of these songs.
It is also believed that these songs may communicate youthfulness, strength and vitality to potential partners.
Male humpbacks can be seen singing either alone or in a group and when together will sing in tune with one another.
Whats more interesting is that even males that are separated over long distances can be found singing the same melody at the same time.
These songs can last anywhere from 5 minutes to a half hour or so and then repeat over the course several hours or days.
Over time these melodies and notes may change but the males will continue to sing these songs in harmony as they continually change.
Whale songs have often been refered to as haunting, beautiful and sad by the people who have heard them.
