We use our hearing to communicate with those around us and interact with our environment. The average hearing range of a person is between 20 Hz – 20 kHz and we use three muscles during listening. However, many animals have much better hearing than we do. Join Toplist to find out which animals have the best hearing on the planet right now!
Moth
The moth has been dubbed the species with the best hearing in the animal kingdom. They can hear frequencies up to 300 kHz, 15 times higher than the highest-pitched sounds we can hear. This moth is believed to have developed such keen hearing to escape its main predator: bats. Bats use high-frequency echolocation to hunt, but larger wax moths can hear bats' calls, giving them a chance to evade their predators.
Moths are not easy to distinguish from ordinary butterflies. Sometimes the name "Heterocera" is used for this butterfly while the term "Rhopalocera" is used for the butterfly to differentiate, however, it has no subspecies value. Many attempts have been made to subdivide the suborder Lepidoptera into groups such as Microlepidoptera and Macrolepidoptera, Frenatae and Jugatae, or Monotrysia and Ditrysia. The failure of these names to survive in modern classification is because none of the names represent a pair of monophyletic groups.
In fact, there is a small group of butterflies born from "moths" (considered as part of the Ditrysia of Neolepidoptera). And as such, there is no way to group all the remaining species in a monophyletic group, which will always exclude a lineage. Furthermore, even their larvae resemble those of beetles (coleoptera).
Bats
Bats are known for their exceptional hearing, although the idea that they have poor eyesight has been widely denied by scientists. Some species of bats use echolocation, which means they emit calls when they fly and use echoes for positioning and navigation. The acoustic vibrations they emit through hiss will bounce off any nearby surfaces back to the bat, allowing them to know where the object is.
Bats are an animal that looks very similar in flight, but the difference between them is in size. The size of the bat depends on the variation in the individual's appearance. The smallest bat species is the Kitti pig-nosed bat, with an average length of 29-34mm and they are classified as the smallest mammals on the planet. Besides, the largest species of bat is the flying fox family with a wing coverage of up to 1.7 meters and a weight of 1kg or 2.2 pounds.
Bats vary widely in color and texture, and their skin color is not uniform in color. With over 1,200 different species of bats, the variety of colors can be overwhelming. In general, its skin color is still mainly dark colors such as dark gray, or brown with yellow-orange ones and combined with yellow and red spots.
The shape of the face, mainly the ears and the snout, varies in texture between families and mainly between genera. In some families, a main textured feature that is fleshy is called the nasal leaf that surrounds the nostrils. The wing shape of bats is actually their arm, in Ancient Greek bat means arm because bats have four long fingers and a thumb, each of which is connected by a layer. membrane as we often see in the feet of ducks and geese.
The peculiarity of bats is that they feed at night and sleep during the day, when they sleep, they often hang upside down and then cling to walls or cliffs and fold their wings around the body like a cocoon to cover the body. they. Bats love the dark, so their sleeping or hiding places are often cliffs or caves, even our roofs.
Owl
As nocturnal, owls rely on both their keen eyesight and hearing. Most owls have asymmetrically set ears; one will be slightly forward and one is set higher than the other. The difference in the position of their ears allows them to pinpoint where the sound is coming from and helps them catch their small prey in the dark.
Most owls have better hearing than other diurnal birds, possibly because they hunt at night. The Barn Owl will use audio frequencies above 8.5 kHz to locate prey movement in the grass, often pausing mid-flight to reorient with motion sounds before swooping down to strike.
Some species of owls, such as the great gray owl, can hunt alone with their hearing, often finding small mammals scattered in the snow. The barn owl has three times more neurons in the medulla (the part of the brain involved with hearing) than the crow.
Even in the dark, owls can easily locate the exact locations of their prey, thanks to a very sophisticated audio signal processing system in their brain. According to a recent study by Dr. Masakazu Konishi of the California Institute of Technology, USA and colleagues, for example, with the rustling sound of a mouse processed by a two-dimensional sound map, it still allows The owl knows immediately where the bait is. This discovery has important implications for the study of how the brain processes information.
In addition, to find out how owls can catch prey in the dark, the team looked at the responses of 14 owls to pairs of sounds. Cellular stimuli recorded in the brain showed that the owl's auditory system created a two-dimensional sound map of its own, based on the sounds it received. The system then multiplies the sounds to even more accurately pinpoint when and where the sound is coming from.
Elephants
Elephants use their hearing and most importantly their ears for many reasons. In addition to excellent hearing, with an average frequency range of 16 Hz – 12 kHz, elephants will use their ears to help them stay cool. In the hot climates where they live, the large surface area and thinness of the ears help regulate body temperature, keeping them cooler for longer. With huge ears, elephants can hear the sound of clouds gathering together before it rains. Elephants can also hear infrasound, which is low frequencies that humans cannot hear. They can also hear with their feet thanks to nerve endings that sense vibrations of the ground. Some animals have receptors on body parts that transmit vibrations and sound waves to the nervous system.
Elephant ears have thick stalks but thin edges. Below the auricle, or outer ear, there are many capillaries. Warm blood flows into the capillaries, helping to release excess body heat to the environment. This process takes place when the ear lobe is stationary and the elephant claps the ear to enhance the effect. The larger the ear area, the more efficiently heat can be eliminated. Of all the elephant species, the African forest elephant lives in the hottest climates and has the largest ear lobes.
Elephants are the largest land animals. The African prairie elephant is the largest of the elephant species; males can be 304–336 cm tall at the shoulder, with a body mass of 5.2–6.9 tons; Females can be 247–273 cm tall at the shoulder, with a body mass of 2.6–3.5 tons. Male Asian elephants have a shoulder height of 261–289 cm and weigh about 3.5–4.6 tons, female Asian elephants are 228–252 cm tall and weigh about 2.3–3 ,1 ton. African forest elephants are the smallest, their males only about 209–231 cm at shoulder height and weighing 1.7–2.3 tons. Male African forest elephants are usually 23% taller than females, while Asian male elephants are only about 15% taller than females.
The elephant skeleton is made up of 326–351 individual bones. African elephants have 21 pairs of ribs, while Asian elephants have only 19 or 20 pairs. The elephant's skull is resilient enough to withstand the stress of the tusks and face head impacts. The back of the skull is very flat and spread out, creating a dome that protects the brain in all directions. Elephant skulls have air-filled honeycomb sinuses, reducing the weight of the skull but maintaining overall strength. The elephant's skull is very large, providing space for the muscles to attach to and support the head. The elephant's lower jaw is sturdy and very heavy. Due to the size of the head, the elephant's neck is relatively short to better support the weight.
Elephants do not have lacrimal glands, and must rely on Harder's glands to keep their eyes moist. A very durable membrane protects the elephant's eyeball. The elephant's field of vision is not good due to the position of the eyes. Elephants are dichroic, they can see well in dim light but not in bright light.
Dog
When you come home and your dog is happy to see you, you might think it's because they heard you coming through the front door. But dogs' hearing is very sensitive and can hear frequencies higher than humans can hear (and generally responds better to these frequencies than lower ones). Dogs' hearing is so sensitive that they can often hear you at home even before you open the door.
Undoubtedly, one of the senses that dogs have developed better is hearing, through which they can perceive sounds at frequencies that are imperceptible to humans. So you have a good idea as humans, we can hear the sound produced from 6 meters away quite clearly, but in the case of our canine friend this increases dramatically. tell, making them perfectly audible at 25 meters or maybe a little more.
But how does a dog's ear work, possibly allowing for this keen hearing? Well, let's start by saying that this organ consists of three parts: the outer ear, the middle ear, and the inner ear. When a sound wave originates on the dog, it is immediately detected by the most exposed part of your ear, the ear, from which the sound is transmitted. The pinna is a very functional organ that allows for good movement, thanks to its 17 muscles.
From there the sound waves travel through the ear canal to the eardrum, which has an L-shaped joint designed to protect it. There, they create vibrations of the eardrum and they cause the small bones to expand them further so that when entering the inner ear the dog can identify the type of sound. It is worth remembering that the middle ear functions to balance our dog's bodyThis is why when there is an abnormality at this time, it can show erratic or reduced movements.
Cat
Not only are cats' hearing very impressive, with an average frequency range of 45Hz - 64,000Hz, but their ears are also mechanically respectable. The human ear consists of three muscles and the three smallest bones in the body; Cats' ears are controlled by about three dozen muscles on each ear that allow them to rotate their ears 180 degrees.
The cat is a very sensitive animal capable of perceiving sounds up to 50,000Hz while humans can only perceive up to 20,000Hz. This difference is so great that even though he can hear the sound of a mouse from 7 meters away, our hearing usually has to combine with our sight to understand what a person is doing. talking while talking on a busy street.
In addition, a cat's ears can be oriented towards the center of the sound thanks to the 27 muscles found in them, allowing them to rotate one by one.
Cats' hearing is exceptionally superior to human hearing. While humans and cats have similar hearing ranges at the lower end of the scale, cats can hear sounds that are much higher in pitch, as we discussed in the previous point.
This means that cats can hear sounds that humans cannot hear at both ends of the spectrum, but especially at the higher end. Cats are not only above the human range, but also far beyond the range of dogs, by at least an octave.
Horse
A herd will always have at least one on watch, to warn the others of potential dangers around them. A horse's hearing is essential to protecting the herd. The primary functions of horse hearing are to detect sounds, determine where it's coming from, determine what the sound is, and know if it's time to warn the herd. Horses also use their ears to communicate their moods. Horse ears have up to 16 muscles on each side, which allows them to shake their ears and rotate them 180 degrees.
Depending on breed, management and environment, food, water etc today horses have a lifespan of about 25 to 30 years. The oldest verifiable horse is "Old Billy", a 19th century horse with a lifespan of 62 years. Currently, Sugar Puff, the horse listed in the Guinness Book of Records as the oldest living pony in the world, died on May 25, 2007 at the age of 56.
Mare pregnancy lasts about 335-340 days. Horses usually give birth to one. Ponies are able to stand and run shortly after birth. Four-year-old horses are considered mature horses, although they continue to develop normally until the age of six, the time to complete the horse's development also depends on the size of the horse, breed, sex and quality take care of.
Much different from the movie, the fact that this animal loves to eat food with sugar essence, if the food is bitter or sour, they will not touch it. If you plan to raise a horse, you should know that their favorite foods are oats, apples, and carrots.
Dolphin
Dolphins have exceptional hearing and vision and also use echolocation to “hear” where they are going (similar to bats). In this case, a dolphin will make a sound, a hiss, which will bounce off the surface and back into the dolphin's lower jaw. The reverberation of sound vibrations provides a sound map of what may lie ahead. The detail of the sound map is impressive and allows the dolphins to not only hunt effectively, but also avoid any danger.
Dolphins are known for their exceptional hearing. But did you know that they have no sense of smell? Dolphins have olfactory regions, but no olfactory nerves. In case you're wondering: "If dolphins can't smell, can they taste?" Indeed, they have taste, but can only perceive salt.
Most dolphins have keen eyesight both in the lips and in the water and can perceive frequencies 10 times higher than humans can hear. Although dolphins have small ears on either side of their heads, it is thought that in water, fish hear with their lower jaws and conduct sound to the middle ear through openings in the jawbone. Hearing is also used to broadcast biological radar, an ability all dolphins have. It is thought that dolphin teeth are used as receptors, they receive incoming sounds and pinpoint the exact position of the subject.
Dolphin's sense of touch is also well-developed, with nerve endings densely distributed over the skin, especially in the nose, pectoral fins and genital area. However, dolphins do not have smell receptors and so they are believed to have no sense of smell. Dolphins also have taste buds and show a preference for certain fish foods. Dolphins spend most of their time under water, sensing the taste of water can help dolphins smell in the same way that the taste of water can tell fish the presence of objects beyond their mouth.
Although dolphins have no hair, they still have hair follicles that help perform some tactile functions. It is believed that the tiny hairs on the Boto river dolphin's beak act as a tactile system to compensate for the species' poor eyesight.
Mouse
Rats are especially good at pinpointing where sounds are coming from because their ears are so close together. The range of a mouse is of the ultrasonic type, which are sounds too high for humans to hear. The mouse can hear with a wide frequency range. They can sense sounds at frequencies from 80 Hz to 100 kHz (i.e. in the ultrasonic range), but are most sensitive in the 15–20 kHz range and about 50 kHz. They communicate by squeaking in the audible range perceived by humans (for remote alarms) and in the ultrasonic range (for close communication).
Because they are primarily nocturnal animals, house mice have little or no ability to perceive colors. The visual apparatus of this rat is basically similar to that of a human. The "tummy" region of the mouse retina has a much higher density of ultraviolet (UV)-sensitive cones than other areas of the retina, although the biological significance of this structure is unknown. .
House mice also use pheromones as social communication signals. The tears and urine of male rats also contain pheromones. Rats detect pheromones mainly by the cane leaf bone located below the nose. The urine of domestic rats, especially male rats, has a strong and characteristic odor. In the urine of rats, at least ten different compounds such as alkanes, alcohols were detected.
The smell of adult males or from pregnant or lactating females can speed up or delay sexual maturation in adolescent females and synchronize the reproductive cycle in adult females. (known as the Whitten effect). The smell of strange male rats can terminate pregnancy, this is the Bruce effect.
Dove
Pigeons can hear infrasound, sounds much lower than humans can hear. With the average pigeon able to hear sounds as low as 0.5 Hz, they can detect distant storms, earthquakes, and even volcanoes. With their exceptional hearing and navigational skills, they are often considered the best navigators in the animal kingdom.
Pigeon's body temperature is stable under changing ambient temperature; Pigeons are endothermic animals. The diamond-shaped body of the bird reduces air resistance in flight. Dry skin covered with feathers. Feathers covering the whole body are tubular feathers, with wide feathers forming wings, the tail of the bird (as a rudder). Feathers that grow close to the body are down. Fluff has only a bunch of thin hairs that form a foam layer that retains heat and makes the bird's body light.
When the bird's wings are spread, they form a large fan, when folded, they are compactly pressed against the body. The hind limbs have long paws with three front toes and one hind toe, all with claws, which help the bird cling to the branches when the bird perches or straighten, spread the toe when the bird lands. The horn beak encloses the toothless jaw, making the bird's head light. Long neck, flexible bird head, promoting the effects of senses (eyes, ears), convenient when catching prey, preening feathers. The buoyancy gland secretes mucus when the bird is preening to make the feathers smooth and waterproof.
Pigeons build relatively flimsy nests, often using sticks and other debris, which can be placed on tree branches, on ledges or on the ground, depending on the species. They lay one or (usually) two white eggs at a time, and both parents take care of the young. They leave the nest after 25 to 32 days. Featherless pigeons are usually able to fly by the time they are 5 weeks old. Unlike most birds, both sexes of pigeons produce "tree milk" to feed their young, which is secreted by shedding fluid-filled cells from their linings.
Rabbit
The rabbits pointed their ears straight in the direction of the sound. Ear movements help rabbits run away from predators. In addition, rabbit ear movements tell us a lot about their behavior. Bunny ears standing up means they are listening attentively.
Rabbits are small mammals in the family Leporidae of the order Lagomorpha, found in many parts of the world. Rabbits are classified into seven categories,[citation needed] such as European hares, cottontail rabbits (genus Sylvilagus; 13 species), Amami rabbits. There are many other rabbit species in the world; cottontails, bobcats and hares are classified in the order Lagomorpha. The lifespan of rabbits is from 4 to 10 years, the gestation period is about 30 days.
Rabbits were first known to humans around 1000 BC in Europe. The European hare is the only domesticated rabbit species. Rabbits are considered pets, for food, for fur and also as destroyers of fields. Domestic rabbits were domesticated from wild hares. In the West, house-raised rabbits are called bunny or bunny rabbits that refer to domesticated baby rabbits.
Winged Insects
When beetles, crickets and moths hear the sonar of their predators, they run away or fly in zigzags or circles to escape the hunt. Some species of crickets and beetles make clicking sounds to scare away predators.
Also, many insects are quite famous for the sounds they make. Examples: Cicadas, crickets, grasshoppers and American grasshoppers all sing their own songs. Many beetles also make sounds, though not as gracefully as their straight-winged cousins. For example, woodworms make "creaking" sounds for many hours…
Cicadas, also known as needles of meditation, are a super family of insects with large heads, two wings with many veins. There are about 2,500 species of cicadas in the world, in both temperate and tropical regions. Cicadas are the most well-known insects because of their larger size, distinctive shape with large heads and ability to make a loud, rustling sound, throughout the summer. In the Appalachian Mountains, Americans call cicadas dry flies because the carcass of the tick remains intact and dry after peeling.
Crickets occur in a variety of environments, from grasslands, scrublands, and forests to swamps, beaches, and caves. Crickets are mostly nocturnal, and males have a loud, persistent crowing to attract females, although some species cannot. Interestingly, this chirping is not coming from the cricket's mouth, but rather is generated through the friction between the wings. Adult crickets are usually seen with two pairs of wings. The front wings are relatively stiff, have the effect of vocalizing and protecting the body; The soft hind wings have the effect of flying. When the male crickets chirp, the vocal teeth of the right front wing and the transverse tendon of the left front wing constantly friction make sounds.
