Sound is one of the most important wayscommunications. Virtually all living organisms make sounds in order to communicate with each other, warn of danger, attract the attention of the opposite sex, and even for orientation in space. And these sounds are different, but one of the most important characteristics of a sound is its volume. Which animal is the loudest on land? And in the ocean? The answer to this question is not as obvious as it seems.
If we consider the class of mammals, thenthe blue whale will be the owner of the loudest voice (it will also be concurrently the loudest inhabitant of the ocean). But if we proportionally compare the volume of the sound with the size of the body, the whale will be far from the first place.
In this case, you can give as an examplewell-known analogy: an elephant can lift and carry a load of a much larger mass than an ant. Moreover, if we consider the transferred weight from the point of view of the ant and the elephant, then the first one can easily drag from place to place a load that exceeds its own body weight. In turn, the elephant can not boast. About the same whale happened to the blue whale and it “lost” in loudness ... to a sea worm.
What is the loudest animal in the ocean
According to the editors of Current Biology,recently discovered off the east coast of the Japanese island of Honshu, the multischeck worm Leocratides kimuraorum, capable of producing a sound volume of up to 157 decibels. The already mentioned blue whale “screams” at a volume of 188 decibels. This is, of course, more, but the whale is a huge multi-meter mammal, and Leocratides kimuraorum has a body length of only 3 centimeters.
In the process of studying individuals, scientists madeunusual discovery. Having placed two Leocratides kimuraorum worms nearby, the scientists noted that they are beginning to fight, scaring the enemy with a very loud sound, like a clatter. The volume of these sounds and scientists measured.
This is interesting: Who lives in a huge dead zone in the middle of the Pacific Ocean?

Experts suggest that in this way wormsprotect their territory and can learn about other individuals that are nearby. In addition, scientists argue that this is the first time in the history of biology, when such small animals can make such loud sounds.
