Top 12 Animals with Exceptional Hearing Abilities

Moths are renowned for having the best hearing abilities in the animal kingdom. They can hear frequencies up to 300 kHz, which is 15 times higher than the highest pitch sounds we can perceive. It's believed that these moths have developed such keen hearing to escape their main predator: bats. Bats use high-frequency echolocation to hunt, but larger wax moths can detect the bat calls, giving them a chance to evade their foes.

Moths are not easily distinguished from butterflies. Sometimes the term 'Heterocera' is used for these moths, while the term 'Rhopalocera' is used for butterflies to differentiate, however, it lacks taxonomic value. Scientists have made various attempts to divide the order Lepidoptera into groups such as Microlepidoptera and Macrolepidoptera, Frenatae and Jugatae, or Monotrysia and Ditrysia. The failure of these names to persist in modern classification is because no one name represents a pair of monophyletic groups.

Indeed, there is a small group of moths born from 'moths' (considered part of Ditrysia of Neolepidoptera). And thus, there is no way to group all other species into a single monophyletic group, it will always be excluding as a descendant lineage. Furthermore, even their larvae resemble beetle larvae (coleoptera).

Nocturnal by nature, the owl relies on both keen eyesight and hearing. Most owl species have asymmetrical ears, with one positioned slightly forward and one placed higher than the other. The difference in ear position allows them to accurately pinpoint the source of sound, aiding them in capturing their small prey in the darkness.

Most owls have better hearing than other daytime hunting bird species, possibly because they hunt at night. The Barn Owl, for instance, uses sound frequencies above 8.5 kHz to locate the movements of prey in grass, often pausing mid-flight to reorient using sound cues before swooping down for an attack.

Some owl species, like the Great Gray Owl, can hunt solo using their hearing, often detecting small mammals running amok beneath the snow. Barn Owls have three times more nerve cells in their nucleus (the brain area related to hearing) compared to hawks.

Even in pitch-black darkness, the Short-eared Owl can accurately pinpoint positions on prey, thanks to its highly sophisticated sound signal processing system in its brain. According to recent research conducted by Dr. Masakazu Konishi of the California Institute of Technology, USA, and colleagues, even with the rustling noise of a mouse processed by a two-way sound map, the Short-eared Owl can immediately discern the prey's whereabouts. This discovery holds significant implications for the study of brain information processing.

Furthermore, to understand why Short-eared Owls can catch prey in the dead of night, this research group examined the response of 14 Short-eared Owls to pairs of sounds. The recorded cell stimuli in the brain showed that the owl's auditory system spontaneously generated a two-way sound map based on the received sounds. Subsequently, this system multiplicatively enhances the sounds to pinpoint even more accurately the time and location from which the sound is emanating.

Bats are renowned for their exceptional hearing, although claims of their poor eyesight have been widely debunked by scientists. Some bat species utilize echolocation, meaning they emit calls while flying and use the echoes to locate and navigate. The sound vibrations they emit through chirps will bounce back from any nearby surface to the bat, allowing them to discern the location of objects.

Bats are a species of flying mammal that share a strikingly similar appearance in flight, with the primary difference being in size. The size of bats depends on the variation in the physical appearance of each individual. The smallest bat species is the Kitti's hog-nosed bat, with an average length ranging from 29 to 34mm, ranking them among the smallest mammals on the planet. Conversely, the largest bat species is the flying fox family, with wing spans reaching up to 1.7 meters and weighing 1kg equivalent to 2.2 pounds.

Bats vary greatly in color and fur texture, with their skin tones not uniform to a single shade. With over 1,200 different bat species, the diversity in hues is vast. Generally, their predominant skin tone remains dark hues like gray-black, or brown with some individuals displaying shades of yellow and orange, coupled with yellow and red spots.

The facial structure, primarily the ears and snout, varies in texture among bat family and mostly among genera. In some families, a prominent feature with texture is the leaf nose, which contains more flesh surrounding the nostril hole. The wing shape of a bat is essentially their arm, in Ancient Greek, the term for bat translates to 'wing arm' because bats have five elongated fingers and a thumb, each connected by a membrane as we typically see in the feet of ducks and geese.

A peculiar trait of bats is their nocturnal feeding habits and daytime roosting, where they often hang upside down suspended and cling to walls or cliffs, folding their wings snugly around their bodies like a cocoon. Bats are highly fond of darkness, hence their sleeping or hiding spots are often on cliffs or caves, even our roof eaves.

When you come home and your dog is thrilled to see you, you might think it's because they heard you walk through the front door. But a dog's hearing is so keen that they can pick up frequencies higher than what humans can hear (and often respond better to these frequencies than lower ones). A dog's hearing is so acute that they can often hear you being at home even before you've opened the door.

No doubt anymore, one of the senses that dogs have developed better is hearing, enabling them to perceive sounds at frequencies that humans cannot discern. So, while you have an idea as a human, we can hear sounds created from a distance of about 6 meters quite clearly, but in the case of our canine friend, this increases significantly, allowing them to hear perfectly at heights of 25 meters or perhaps a little more.

But how do a dog's ears work to enable this acute 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 an impressive sound wave hits your dog, it's immediately detected by your ear's most contact part, the pinna, from which this sound is transmitted. The ear flap is a highly functional part that allows for good movement, thanks to its 17 muscles.

From there, the sound waves pass through the ear canal to the eardrum, which has an L-shaped joint designed to protect it. There, they cause vibrations of the eardrum and make the small bones expand them further so that when they enter the inner ear, the dog can determine the type of sound. It's worth noting that the middle ear serves the function of maintaining balance for the dog's body. This is why when there's an anomaly at this point, it may manifest as irregular movements or a decrease.

Elephants utilize their hearing, with their ears being crucial for several reasons. Besides their excellent hearing ability, with an average frequency range of 16 Hz – 12 kHz, elephants use their large ears to help regulate body temperature, keeping them cooler for longer in hot climates. With their gigantic ears, elephants can hear the sound of distant thunderstorms before the rain arrives. They can even hear infrasound, which are low-frequency sounds that humans cannot detect. Additionally, elephants can hear through their feet thanks to sensory nerve endings that detect ground vibrations. Some animals have receptors on body parts that transmit vibrations and sound waves to the nervous system.

An elephant's ear has a thick base but thin edges. Beneath the ear flaps, or outer ears, lie numerous blood vessels. Warm blood flows into these blood vessels, allowing excess body heat to be released into the environment. This process occurs when the ear flaps are held still and the elephant flaps its ears to enhance the effect. The larger the ear surface area, the more efficiently heat can be dissipated. Among all elephant species, African savanna elephants living in the hottest climates have the largest ear flaps.

Elephants are the largest land animals. African savanna elephants are the largest among elephant species, with males standing between 304–336 cm at the shoulder, with body masses ranging from 5.2–6.9 tons, while females can stand between 247–273 cm at the shoulder, with body masses ranging from 2.6–3.5 tons. Asian elephants have males standing around 261–289 cm at the shoulder and weighing about 3.5–4.6 tons, while females stand around 228–252 cm at the shoulder and weigh about 2.3–3.1 tons. African forest elephants are the smallest species, with males standing only about 209–231 cm at the shoulder and weighing 1.7–2.3 tons. African forest elephant males are typically 23% taller than females, whereas Asian elephant males are only about 15% taller than females.

An elephant's skeleton consists of 326–351 individual bones. African savanna elephants have 21 pairs of ribs, while Asian elephants have only 19 or 20 pairs. The elephant skull is elastic enough to withstand the stress of tusk impacts and absorb direct collisions. The back of the skull is very flat and wide, providing a protective vault for the brain in all directions. The elephant skull has honeycomb-like sinuses that contain air, reducing the weight of the skull while still maintaining overall strength. The elephant skull is very large, providing surface area for muscles to attach and support the head. The lower jaw of an elephant is robust and very heavy. Due to the size of the head, an elephant's neck is relatively short to better support the weight.

Elephants do not have tear ducts and rely on the Harderian gland to keep their eyes moist. A tough conjunctival membrane protects the eyeballs of elephants. The visual field of elephants is not great due to the position of their eyes. Elephants are dichromatic, meaning they can see clearly in dim light but not in bright light.

A herd of horses will always have at least one keeping watch, to alert the others to potential dangers that may arise around them. The horse's hearing is crucial for herd protection. The main functions of a horse's hearing are to detect sounds, determine their source, identify the sound, and know when it's time to alert the herd or not. Horses also use their ears to convey their mood. A horse's ear has up to 16 muscles on each side, allowing them to flick and rotate them at a 180-degree angle.

Depending on the breed, management, environment, diet, water intake, etc., horses today have a lifespan of about 25 to 30 years. The longest-lived horse on record is 'Old Billy,' a horse that lived in the 19th century and reached the age of 62. Currently, Sugar Puff, a horse listed in the Guinness World Records as the oldest living pony, died on May 25, 2007, at the age of 56.

A mare's gestation period lasts approximately 335-340 days. Horses typically give birth to one foal. Foals are capable of standing and running for a short time after birth. A four-year-old horse is considered mature, although they continue to develop normally until the age of six. The time it takes for a horse to complete its development also depends on the size of the horse, breed, gender, and quality of care.

Unlike what's often depicted in movies, in reality, this animal loves to eat food with a sweet taste, and they won't touch anything bitter or sour. If you plan to keep a horse, you should know that their favorite foods include oats, apples, and carrots.

Not only is the hearing of cats impressive, with an average range from 45Hz to 64,000Hz, but their ears are also mechanically remarkable. A human ear consists of three muscles and three of the smallest bones in the body, while a cat's ear is controlled by about three dozen muscles per ear, allowing them to rotate their ears 180 degrees.

A cat is an incredibly sensitive animal capable of detecting sounds up to 50,000Hz, whereas humans can only perceive a maximum of 20,000Hz. This difference is so significant that while they can hear a mouse from as far as 7 meters away, our hearing often has to be combined with our vision to understand what someone is saying when conversing on a busy street.

Furthermore, a cat's ear can be oriented towards the center of sound thanks to the 27 muscles found within, allowing them to pivot each one individually.

Cats' hearing is particularly superior to humans. While humans and cats have a similar range of hearing at the lower end of the scale, cats can hear sounds much higher, as discussed earlier.

This means that cats can hear sounds that humans cannot at both ends of the spectrum, but especially at the higher end. Cats not only surpass the range of humans but also far exceed that of dogs, at least by an octave.

Mouse are particularly adept at accurately pinpointing the source of sounds due to their ears being too close together. The range of a mouse falls into the ultrasonic category, sounds too high for humans to hear. Mice can hear within a wide frequency range. They can sense sounds ranging from 80 Hz to 100 kHz (meaning within the ultrasonic range), but are most sensitive in the range of 15–20 kHz and about 50 kHz. They communicate by squeaking within the range of human perception (for distant warnings) and in ultrasonic range (for close communication).

Being primarily nocturnal animals, house mice have little to no ability to discern colors. The visual system of this mouse species is essentially similar to humans. The “belly” region of the mouse's retina has a much higher density of cone-shaped cells sensitive to ultraviolet (UV) rays than other areas of the retina, although the biological significance of this structure is not well understood.

House mice also use pheromones as communication signals within their society. Tears and urine of male mice also contain pheromones. Mice detect pheromones primarily through the vomeronasal organ located beneath the nose. The urine of house mice, especially males, has a strong and distinctive odor. In mouse urine, at least ten different compounds such as alkanes, alcohols, etc., have been detected.

The odor of mature males or from pregnant or lactating females can accelerate or decelerate sexual maturity in adolescent females and synchronize reproductive cycles in mature females (known as the Whitten effect). The odor of strange male mice can terminate pregnancies, which is known as the Bruce effect.

Dolphins possess exceptional hearing as well as vision and also employ echolocation to “hear” where they're about to go (similarly to bats). In this case, a dolphin emits a sound, a squeak, that bounces off surfaces and returns to the dolphin's lower jaw. The rebounding sound vibrations provide a sound map of what may lie ahead. The detail of this sound map is impressive and allows dolphins not only to hunt prey efficiently but also to avoid any dangers.

Dolphins are known for their exceptional hearing. But did you know that they lack a sense of smell? Dolphins have olfactory areas, but they lack olfactory nerves. If you're wondering, “If dolphins can't smell, do they have taste?” Indeed, they do have taste but can only sense the taste of salt.

Most dolphins have keen eyesight both in and out of the aquatic environment and can perceive high frequencies ten times those audible to humans. Although dolphins have small ear openings on either side of their heads, it is believed that in the aquatic environment, they hear through the lower jaw and conduct sound to the middle ear through open slots in the jawbone. Hearing is also utilized for bio-sonar, a capability all dolphin species possess. It is believed that dolphin teeth are used as sensory organs, picking up sounds and accurately pinpointing the location of objects.

The sense of touch in dolphins is also well-developed, with densely distributed nerve endings on the skin, especially in the nose, chest fins, and genital region. However, dolphins lack smell-sensitive nerve cells and are therefore believed to lack a sense of smell. Dolphins also have taste and exhibit preferences for certain fish foods. Most of a dolphin's time is spent underwater, and the taste of water may help dolphins to smell in a way, as the taste of water can inform the dolphin of the presence of objects outside its mouth.

Despite dolphins not having fur, they still have hair follicles that serve some tactile functions. It is believed that the small hairs on the snout of the Amazon River dolphin act as a tactile system to compensate for this species' poor vision.

Rabbits orient their ears straight towards sounds emitted. Ear movements help rabbits escape from predators. Additionally, the ear movements of rabbits provide insights into their behavior. Upright ears mean they are attentively listening.

Rabbits are small mammals classified in the family Leporidae within the order Lagomorpha, inhabiting various regions worldwide. Rabbits are categorized into seven types,[citation needed] such as European hares, cottontail rabbits (genus Sylvilagus, 13 species), and Amami rabbits. There are many other rabbit species worldwide, including cottontails, hares, and European rabbits, classified under the Lagomorpha order. The lifespan of a rabbit ranges from 4 to 10 years, with a gestation period of about 30 days.

The rabbit species was first recognized by humans around 1000 years BC in Europe. The European hare is the only rabbit species to be domesticated. Rabbits are known as pets, food sources, fur providers, and also as garden pests. Domestic rabbits are bred from wild European rabbits. In the Western world, a domesticated rabbit is called a bunny or bunny rabbit, referring to a domesticated young rabbit.

When beetles, crickets, and moths hear the ultrasonic waves of predatory meat-eating species, they will flee or fly in a zigzag or circular pattern to escape the hunt. Some species of crickets and beetles emit sound bursts to drive away predators.

Moreover, many insects are quite famous for the sounds they produce. For example: Cicadas, crickets, grasshoppers, and American katydids all sing their own songs. Many beetle species also produce sounds, although not as melodious as their counterparts in the Order Orthoptera. For example, woodworms create a 'creaky' sound for many hours...

Cicadas, also known as the tree cricket, are a superfamily of insects with large heads and wings with numerous veins. There are about 2,500 species of cicadas worldwide, in both temperate and tropical regions. Cicadas are the most well-known insect species due to their large size, distinctive appearance with a large head, and the ability to create buzzing, whining sounds throughout the summer. In the Appalachian region, Americans call cicadas 'jarflies' because their bodies remain intact and dry after molting.

Crickets are found in various habitats, from grasslands, shrubs, and forests to marshes, beaches, and caves. Most cricket species are nocturnal, with males producing loud, sustained chirping to attract females, although a few species do not chirp. Interestingly, this resonant sound is not emitted from the cricket's mouth but is generated through friction between the wings. Adult crickets typically have two pairs of wings. The front wings are relatively stiff, serving to produce chirping sounds and protect the body, while the hind wings are membranous and aid in flight. When a male cricket chirps, the file of the right forewing and the scraper of the left forewing continuously rub against each other to produce sound.
