Can whales bark? What is the cry of narwhals?

Whales can call, and each animal has its own unique sound. So far, scientists have found at least 30 kinds of whale calls, each with its own characteristics and characteristics, which is very interesting.

First of all, the sounds of some whales

There are many whales in nature, and their calls are very surprising and unbelievable. For example, the well-known blue whale has a very loud voice, sometimes its cry can last for a long time, and its voice is louder than the engine of a jet plane. Is it really worthy of being in the animal kingdom? Giant? Ah. And Moby Dick, who is also well known, is also famous in the whale world? A ventriloquist? Scientists recorded the sound of beluga whales in their gathering places and found that the sound of beluga whales can be like the roar of wild animals such as tigers, the cry of hungry children, and the painful gasp of people who have been ill in bed for a long time, which really makes people admire the wonder and magic of nature.

Second, the reason why all whales can't hear.

Some whales are inaudible to humans. This is because the sound that humans can hear is only 20Hz to 20000Hz, and the range is very small. Even if infrasound waves below 20Hz and ultrasonic waves above 20000Hz enter people's ears, people can't hear them. That's why humans can't hear all the whales.

Third, the call of narwhals.

Narwhals sound a bit like electric drills. Will it shine? Buzzing? The sound is very interesting, and it will change with the distance from food. Narwhals live in the Arctic Ocean, where the climate is cold, covered with snow all year round and sparsely populated, which also makes it difficult for people to hear the voice of narwhals. But the Inuit who also live in the Arctic Ocean mainly feed on narwhals, so they often deal with narwhals. Thanks to the joint efforts of scientists and Inuit, the precious audio of narwhal calls has been obtained.
