Whales are social creatures that use a variety of sounds to communicate and socialize with each other. 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
Marine mammals, including whales, dolphins, and porpoises, are much more dependent on sound than land mammals due to the limited effectiveness of other senses in water.
Communication with extraterrestrial intelligence (CETI) is a branch of the search for extraterrestrial intelligence (SETI) that focuses on composing and deciphering interstellar messages
Communicating between species isn’t something that only has to take place between space-faring civilizations. There are plenty of species here on our home planet that communicate using a variety of sights, sounds, and smells
Researchers at the SETI Institute think that doing so might be a good test for whether we’ll be able to communicate with extraterrestrials if we ever get the chance to
Luckily, there are plenty of opportunities to practice. One of the most fascinating creatures with clearly discernible communication is the humpback whale
Humpback whales are known for their complex communication, which includes both songs and social calls. They are also known for their affinity for humans and their songs that can travel up to 10,000 miles.
Here are some details about humpback whale communication:
- Vocalizations Humpback whales produce a number of vocalizations, including moans, grunts, blasts, shrieks, and groans. They can also create melodic sounds similar to human music.
- Songs Male humpback whales can sing a 30-minute long song and sing that song repeatedly for hours. The whale songs are loud, complex, and change over time. They sing during courtship and also while feeding and migrating.
- Social sounds Humpback whales also make a range of other social sounds to communicate such as “grunts”, “groans”, “thwops”, “snorts”, and “barks”.
- Social systems Humpback whales are extremely intelligent, have complex social systems, and make tools.
Studying them has been a focal point of the Whale-SETI team from the Search for Extraterrestrial Intelligence (SETI) Institute,
The Whale-SETI team from the Search for Extraterrestrial Intelligence (SETI) Institute has been studying humpback whale communication systems. The team’s goal is to develop intelligence filters to help search for extraterrestrial intelligence.
SETI is a scientific effort to detect electromagnetic signals that may indicate the existence of intelligent life. SETI projects use techniques such as radio transmissions and optical signals to look for signs of technological activity from other planets
In a flurry of exchanged messages, the scientists sent a “contact” call that drew Twain’s attention and had him circling their boat for around 20 minutes.
He responded to every burst of sound from the scientists and matched the intervals of delay between sounds in what they called in a press release a “conversational style.”
While the scientists understood they were saying some equivalent of “hello” to Twain when he arrived, that’s about as far as their understanding went. Luckily, there’s a theory for that – in this case, a mathematical one called “information theory.
Information theory is a mathematical study of how information is quantified, stored, and communicated. It’s also known as the mathematical theory of communication
Humpback whales are known for their complex social structures and communication methods. They use whistles and other vocal communication. Calves develop unique “signature whistles” that they use throughout their lives
The Whale-SETI team aims to apply lessons learned from this research to develop intelligence filters. These filters could be applied to any extraterrestrial signals that scientists might pick up. Using the mathematics of information theory, scientists could spot rule structures that could help them translate the message.
SETI is an effort to answer the question of whether we are alone in the Universe. SETI projects use various techniques to look for signs of technological activity coming from other planets, such as radio transmissions and optical signals.
Humpback whales are considered highly intelligent animals. They have complex social structures and can learn from each other. They also have strong communication abilities and can show emotion
Here are some other characteristics of humpback whales that demonstrate their intelligence:
- Brains Humpback whales have brains that can weigh up to a ton. Their brains contain specialized brain cells called spindle neurons, which are associated with advanced abilities such as recognizing, remembering, reasoning, communicating, perceiving, adapting to change, problem-solving, and understanding.
- Social systems Humpback whales have complex social systems and make tools, such as nets out of bubbles, to catch fish. They also communicate extensively with both songs and social calls.
- Migrations Humpback whales have some of the longest migrations of any mammal, with some populations swimming 5,000 miles (8,047 km) between breeding and feeding grounds.
- Protecting other species Humpback whales have been known to play with and protect other species such as dolphins, seals, smaller whales, and humans.
