YOGYKARTA - Mamalia is known as a group of animals capable of living in various habitats around the world. One of the main characteristics of mammals is the presence of a milk gland, which allows them to breastfeed their cubs. In addition, mammals belong to a group of vertebrates, namely animals that have a spine or vertebra column, extending from neck to tail.
However, there are some mammals that are unique because they do not have a sound band, the organs that other animals usually use to produce sound. So, what mammal does not have a sound band? Here are some examples.
Mamalia Characteristics
Mamalia is a very diverse group of animals, with their own uniqueness that makes them prominent in the animal world. In John Farndon and Jon Kirkwood's book Mini Animal Encyclopedia (2003), it is explained that mammals are hot-blooded vertebrates that can be found on land, air, and water. One unique aspect of some mammals is their inability to produce sound due to the absence of sound bands.
Sound bands, in general, are a pair of mucus membrane folding in the larin that can vibrate and produce sound. Most vertebrates have sound bands to communicate or express themselves. However, it turns out that there are several types of mammals that do not have sound bands, so they use other means of communicating. These are some of them.
1. Dolphin
Dolphins are one of the marine mammals known for its intelligence. These animals have a unique communication system called sonar, or echolocation. By using sonar, dolphins can recognize the surrounding objects and avoid collisions.
Even though it doesn't have a sound band, the dolphins can still produce sound, but in a different way. The sound is generated through the dorsal exchange network on their nose, which allows them to keep in touch even without the sound band.
2. Rabbit
Many people think of rabbits as calm and quiet animals. In fact, rabbits do not have the ability to produce sounds with the sound band. Instead, rabbits make sounds by swiping their teeth, especially when chewing food.
In certain situations, such as when angry or feeling threatened, rabbits can make sounds in the form of anger. However, in general, rabbits are mammals that fall into the "silence" category due to the absence of sound bands.
3. Whale
As the largest mammal in the sea, whales also do not have a sound band. Just like dolphins, whales produce sound through a sonar mechanism. Whales are able to produce low-frequency sound by flowing air through lines or special tissues.
This noise serves for long-range communication between whales, although it does not result from sound band vibrations. The absence of sound bands in whales shows unique adaptation that allows them to communicate in extensive marine conditions.
4. Giraffe
Giraffes are the tallest land mammals known to have long necks, which are useful for reaching leaves at the top of a tree. Many people view giraffes as calm animals because they rarely sound sound.
Apparently, the real reason is because the giraffe does not have a sound band. Its long neck makes it difficult for the air to shake the sound band, so the giraffe cannot make sounds like most other animals. Even without a sound band, giraffes can still communicate through body signals or neck movements.

Why Don't Some Mamalia Have Voice Bands?
The existence or absence of sound bands on mammals relies on their communication needs and environment. Marinely living mammals, such as dolphins and whales, use sonar instead of sound bands, which are effective in underwater communication.
Meanwhile, land mammals such as giraffes and rabbits may not need sound to communicate as intensively as other animals, so evolution does not support the development of sound bands on them.
The Importance Of Understanding The Uniqueness Of Mamalia Without Sound Bands
Knowing what mammals do not have a sound band gives us insight into the diversity of animal adaptations in different environments. These animals have developed unique ways to communicate or express themselves without sound, demonstrating the flexibility of nature in creating solutions for each species. By studying animals such as dolphins, whales, rabbits, and giraffes, we can better understand the extraordinary adaptation that occurs in the animal world.
Talking about Mamalia, it turns out that Platipus, Mamalia is'strange' from Australia who is threatened with Extinction, reportedly her habitat has shrunk by 22 percent, wow!
