To this day, humans are trying to study and explore the secrets of the animal world, but the secrets of creation may be a real dilemma for scientists, especially when they try to study some creatures in harsh, incomprehensible and very wide environments that are difficult to quantify in the laboratory, such as the oceans.
Scientists believe that to this day, and despite the great progress in science techniques and tools, they estimate some scientific details, roughly, including but not limited to drunkenness, the weight of the blue whale, as man has not been able to this day to accurately measure the weight of this great creature Because there is no machine that can carry it, but they estimate the weight at about 100 tons, and it may reach 200 tons according to estimated studies.
“Mysterious song” needs to be decoded
But blue whales and some other types of whales have another unique secret, which is the “song of the sea”, where these huge creatures communicate with each other by singing or some sounds, and because the sound is heard in water 4 times faster than air, so it is ideal more than vision or other senses.
Surprisingly, whale songs, such as some types of blue whales, are not easy to notice, because they are slow-tempo songs, as they take the form of a continuous roar in the sea, but after recording this sound for a long time, scientists found when speeding up the recordings, that in total, it forms a continuous song It is continuous and balanced, and not just noise, according to the “dosits” organization, which specializes in the sounds of the sea.
A blue whale’s sapphire “strike” is a “powerful blast” of water almost as thick as a man’s arm and about 6 meters (20 feet) above sea level.
The huge openings on the top of the blue whale’s head are considered the front of the whale’s respiratory system, like the nose for drunkenness, but scientists have linked the whale’s voice or singing to this nose or its respiratory system, not the mouth, as the whale cannot open its mouth “like humans” to bring out the sound through the air. Coming from the vocal cords, the human vocal cords simply restrict airflow like doors, while the vocal cords of whales form more complex structures attached to special sacs at the bottom of their throats.
Scientists have suggested that when the whale is under water, it passes air from the vocal cords connecting these sacs and the lungs, allowing the whales to sing without losing air, which made some say that these whales sing from their noses, that is, from their respiratory system and not from their understanding, but the matter still obscure
A sound stronger than an airplane hears “without ear”
These large animals emit very deep roaring sounds, with some divers reporting that blue whale sounds are more “perceptible” than audible.
According to the “coolantarctica” website, which specializes in the whale world, blue whales emit deep, low-pitched sounds that were recorded at 188 decibels (about one meter from the whale), which is much louder than the loudest sound issued by any animal on Earth. Suffice it to say; A large airliner makes a noise or roar of 120 decibels on takeoff.
According to the source, blue whales can hear the sound at a distance of more than 500 miles (800 km), although they do not have an external ear, that is, they do not have large, circular-shaped openings. Rather, they have an ear buried inside their skulls, but they are connected with the world. The outer part is through an arm that reaches the whale’s skin, and scientists believe that this arm picks up the frequencies received by the whale’s body.
