The loudest animal in the world is the sperm whale (Physeter macrocephalus). Sperm whales can produce clicks that are louder than any other sound made by an animal, with some clicks reaching 230 decibels. To put that into perspective, a jet engine at takeoff produces around 150 decibels, and prolonged exposure to sounds above 120 decibels can cause hearing damage in humans. Sperm whales use these clicks for echolocation to navigate and find prey in the dark depths of the ocean.

The World’s 10 Loudest Animals

Here are the world’s top 10 loudest animals, ranked by the intensity of their vocalizations:

Sperm Whale

Sperm Whale

The sperm whale is the loudest animal in the world, capable of producing sounds that can reach up to 230 decibels. The sperm whale (Physeter macrocephalus) is the largest of the toothed whales and can grow up to 60 feet long, with males being larger than females. Sperm whales have a distinctive, block-shaped head that makes up about one-third of their body length.

They are found in all the world’s oceans, from the equator to the polar regions, and are capable of diving to depths of over 7,000 feet in search of their preferred prey, giant squid. Sperm whales are known for their powerful clicks, which they use for echolocation to navigate and locate prey. These clicks are the loudest sounds made by any animal, with some clicks reaching up to 230 decibels, making them louder than a jet engine.

Sperm whales also use vocalizations to communicate with each other, with males producing loud, repetitive clicks during mating season.

Unfortunately, sperm whales have been heavily hunted for their oil and meat, and their populations have declined significantly over the past few centuries. Today, they are protected under international law, but they still face threats from pollution, climate change, and entanglement in fishing gear.

Howler Monkey

Howler Monkey
Howler monkeys are known for their loud and deep roars, which can travel over three miles through dense forest canopies. Howler monkeys are a group of New World monkeys that are found in Central and South America. They are known for their distinctive, deep howls, which can be heard for up to three miles through dense rainforest canopies.

Howler monkeys have a specialized hyoid bone in their throat that allows them to amplify their vocalizations. They use their howls to communicate with other members of their troop, as well as to mark their territory and attract mates. In addition to their howls, they also produce grunts, screams, and other vocalizations.

Howler monkeys are arboreal, spending most of their time in trees, and they are primarily herbivorous, feeding on leaves, fruit, and flowers. They are social animals and live in groups of up to 20 individuals, which are led by a dominant male. Females typically remain in the group their entire lives, while males may leave to join another troop as they mature.

Despite being the loudest of all the primates, howler monkeys are not considered to be endangered. However, their populations are threatened by habitat loss and fragmentation, as well as hunting for their meat and pelts.

African Elephant

African Elephant
Elephants use a variety of vocalizations, including low-frequency rumbles that can be heard up to 6 miles away. The African elephant (Loxodonta africana) is the largest land animal in the world and is found in 37 countries in sub-Saharan Africa. Adult males can weigh up to 14,000 pounds and stand over 10 feet tall at the shoulder. They have distinctive tusks, which are elongated incisor teeth, that are used for defense, digging for food and water, and foraging.

African elephants are highly intelligent and social animals, living in family groups led by a matriarch. They use a variety of vocalizations, including low-frequency rumbles that can be heard up to 6 miles away, to communicate with other elephants in their group and to navigate their environment. They also use non-vocal communication, such as body language and touch, to communicate with each other.

Unfortunately, African elephants are facing a number of threats, including habitat loss and fragmentation, poaching for their ivory tusks, and human-elephant conflict. Despite being protected under international law, their populations have declined significantly over the past century, and they are now considered to be vulnerable to extinction. Conservation efforts are underway to protect and conserve African elephant populations and their habitats.


The lion’s roar is a powerful sound that can be heard up to 5 miles away and is used to communicate with other lions. The lion (Panthera leo) is a large, carnivorous mammal that is native to sub-Saharan Africa and a small population in India. Lions are the only truly social cats, living in groups called prides that can include up to three males, a dozen females, and their young.

Lions are famous for their powerful roar, which can be heard up to 5 miles away and is used to communicate with other lions. The roar is produced by the lion’s vocal cords, which are longer and thicker than those of other big cats, and by the air sacs in their chest. In addition to roars, lions use a range of vocalizations, including growls, snarls, and meows, to communicate with each other.

Lions are apex predators, hunting and feeding primarily on large ungulates such as zebras, wildebeest, and buffalo. They are highly adaptable and can thrive in a variety of habitats, including grasslands, savannas, and even forests. However, lion populations have declined significantly in recent years due to habitat loss, human-wildlife conflict, and poaching for their bones, skins, and other body parts. They are currently classified as vulnerable by the IUCN Red List of Threatened Species.

Blue Whale

Blue Whale
The blue whale is the largest animal on earth and can produce a vocalization that reaches up to 188 decibels, which can be heard over 500 miles away. The blue whale (Balaenoptera musculus) is the largest animal on Earth, reaching lengths of up to 100 feet and weighing as much as 200 tons. Blue whales are found in all of the world’s oceans and are known for their distinct blue-grey coloration and mottled appearance.

Blue whales produce some of the loudest sounds made by any animal, including their famous low-frequency vocalizations, known as songs. These songs can last for hours and can be heard over vast distances, up to 1,000 miles away. Blue whales use these songs to communicate with other whales, attract mates, and possibly to navigate their environment.

Blue whales are baleen whales, which means they filter feed on small crustaceans called krill. They have a specialized feeding mechanism that allows them to take in huge volumes of water and then filter out the krill using their baleen plates. Blue whales are migratory, traveling long distances in search of food and breeding grounds.

Unfortunately, blue whales were hunted almost to extinction during the whaling era, and their populations are still recovering. Today, they are protected under international law, and conservation efforts are underway to protect and conserve their populations and habitats.

Greater Bulldog Bat

Greater Bulldog Bat
The Greater Bulldog Bat can produce echolocation calls that are over 140 decibels, making it the loudest bat in the world.
The greater bulldog bat (Noctilio leporinus) is a species of bat found in Central and South America, including parts of Mexico, Brazil, and Argentina. It is known for its unique hunting technique, which involves using echolocation to locate prey and then capturing it with its large, powerful jaws.

Greater bulldog bats are relatively large, with a wingspan of up to 2 feet, and are typically brown or gray in color. They are nocturnal, and feed primarily on fish, which they capture by skimming the water’s surface with their large, specially adapted feet. When they detect a fish with echolocation, they use their strong jaws and sharp teeth to capture and eat it.

While greater bulldog bats are not particularly loud compared to some other bat species, they are capable of producing high-frequency echolocation calls that help them locate prey in the dark. They also use social calls to communicate with other bats, particularly during mating season.

Like many other bat species, the greater bulldog bat faces a number of threats, including habitat loss, hunting, and the spread of diseases like white-nose syndrome. Conservation efforts are underway to protect and conserve bat populations and their habitats, including efforts to reduce human disturbance and improve the availability of roosting and foraging sites.

Tiger Pistol Shrimp

Tiger Pistol Shrimp
The snapping sound produced by the Tiger Pistol Shrimp can reach up to 200 decibels, which is louder than a gunshot.
The tiger pistol shrimp (Alpheus bellulus) is a small marine crustacean found in the tropical waters of the Indo-Pacific region, including the Great Barrier Reef. It is known for its unique ability to produce a loud popping sound by snapping its oversized claw shut, which creates a shockwave that stuns and kills small prey.

The snapping sound of the tiger pistol shrimp is one of the loudest sounds produced by any marine animal, reaching up to 218 decibels at close range. The sound is so loud that it can stun or even kill small fish and invertebrates, allowing the shrimp to easily catch and consume them.

In addition to its powerful snapping ability, the tiger pistol shrimp has a symbiotic relationship with goby fish. The shrimp creates and maintains a burrow in the sand, which the goby fish shares. The goby fish keeps watch for predators while the shrimp works on expanding the burrow. If a predator approaches, the goby fish will warn the shrimp by touching it with its body, and the shrimp will retreat into the safety of its burrow.

Tiger pistol shrimp are popular in the aquarium trade because of their fascinating behavior and unique abilities, but they are also important members of the marine ecosystem, helping to control populations of small invertebrates and contributing to the overall health of coral reefs.


The Kakapo is a flightless parrot from New Zealand that can produce a loud booming call that can be heard up to 3 miles away. The kakapo (Strigops habroptilus) is a flightless, nocturnal parrot native to New Zealand. It is one of the rarest and heaviest parrots in the world, with only around 200 individuals remaining in the wild.

The kakapo is known for its distinctive appearance, which includes a mossy-green plumage, a rounded body, and large, expressive eyes. It is also known for its unusual behavior, which includes a lek mating system in which males gather in specific locations to attract females with their distinctive booming calls.

While the kakapo is not necessarily loud, it is known for its unusual vocalizations, which include screeches, whistles, and growls. These vocalizations are used for a variety of purposes, including communication, mating, and territorial defense.

The kakapo is critically endangered due to habitat loss, introduced predators, and other threats. Conservation efforts are underway to protect and conserve remaining populations, including habitat restoration, predator control, and a captive breeding program.

American Alligator

American Alligator

Alligators produce low-frequency roars that can travel great distances through water, allowing them to communicate with other alligators. The American alligator (Alligator mississippiensis) is a large, semi-aquatic reptile that is native to the southeastern United States. It is one of the largest reptiles in North America, with males reaching lengths of up to 14 feet and weighing up to 1,000 pounds.

Alligators are known for their distinctive, booming roar, which is produced by males during the breeding season. The roar is made by air being expelled from the lungs through the vocal cords and into an expandable pouch in the throat called a bellowing chamber. The bellowing chamber amplifies the sound, producing a deep, resonant roar that can be heard for long distances.

In addition to their impressive vocal abilities, alligators are apex predators that play an important role in their ecosystems. They primarily feed on fish, turtles, birds, and small mammals, and help to control populations of these animals. Alligators also create and maintain wetland habitats by digging burrows and creating channels, which provide important habitat for a variety of other species.

While the American alligator was once listed as endangered due to overhunting and habitat loss, conservation efforts have been successful in bringing the species back from the brink of extinction. Today, alligator populations are considered to be stable, and hunting is closely regulated to ensure that populations remain healthy.

Humpback Whale

The Humpback Whale produces complex songs that can last up to 20 minutes and can be heard over long distances. The humpback whale (Megaptera novaeangliae) is a large marine mammal that is found in oceans around the world. They are known for their impressive acrobatic displays, including breaching, tail slapping, and spy-hopping, as well as for their haunting and complex vocalizations, known as songs.

Humpback whales are famous for their songs, which are some of the most complex vocalizations made by any animal. The songs are made up of a series of moans, cries, and other sounds, which are repeated in a specific pattern. These songs can last for up to 20 minutes and can be heard by other humpback whales for distances of up to 20 miles.

Humpback whales are migratory animals, traveling long distances each year between their feeding and breeding grounds. They feed primarily on small fish and krill, and are known for their unique feeding behavior, called bubble net feeding, in which they work together to create a “net” of bubbles that traps their prey.

Despite their large size and strength, humpback whales were heavily hunted during the whaling era, and their populations were severely depleted. Today, humpback whales are protected under international law, and conservation efforts are underway to protect and conserve their populations and habitats.
