Raymond WhitneyThere are animals that do not create noises. In any case, they do not produce the kind of sound that can be heard by the human ear.
There are two major kinds of animal sounds. Both vocal and mechanical.
Animals make use of vocal sounds for a variety of reasons. To show dominance, to draw a mate warnings about territory, when threatened, or to communicate with other animals.
Mechanical noises are the sounds animals make when eating, moving, or fighting.
Making sounds is an essential part of the daily routine of the majority of species.
Today, however, we’ll look at animals that are silent. Silent animals who make minimal or no sound out from their mouths.
Which animals make no sounds?
- Jellyfish
- Snails
- Butterflies
- Crabs
- Sharks
- Goldfish
- Sea Urchins
- Worms
- Starfish
- Sea Cucumber
- Sea Anemones
- Sponges
- Clams
- Sea Lilys
- Sea Squirts
- Man O’Wars
- Rabbits
- Snakes
- Giraffes
- Sloths
- Turtles
- Lizards
- Octopus
14. Jellyfish
There’s a valid reason why jellyfish don’t make noises.
It’s likely that you enjoy swimming in the sea. The jellies can be fun to look at but some of them can sting you. Therefore, it is better to have them not totally silent.
However, they are.
Jellyfish are extremely simple creatures and are part of a group of animals that do not have the capacity to produce any type of communication.
They just float around and feed.
13. Worms
Worms don’t communicate with each other using sound.
To communicate, they make use of the senses of touch or tasting. They are able to feel vibrations easily (in the earth) and when they feel the earth shake, they’ll swiftly move up towards the surface. They will do so in order to avoid getting caught by an enemy.
However, Worms spend the majority of their lives in the ground or under rocks and stones therefore why should they be quiet. There’s nobody to talk with under the ground anyway.
12. Sea Urchins
Sea Urchins don’t communicate with their mouths. They do not even have brains as well (just like jellies).
Sea Urchins are very basic animals that only move around and eat.
There is therefore no message that can be heard via its mouth. The only sound you’ll get from the animal is the tiny legs that walk on the small pebbles at depths of the sea (or at the Aquarium).
Sea Urchins eat algae from the rocks and do so in a quiet manner. But you may hear some tiny scratching sounds if you are completely silent around it. This is the result of teeth grinding algae!
11. Gold Fish
You’d think that fish are completely quiet all the time.
However, you could be mistaken.
There is a variety of fish that have the ability to make the sounds of a vocal. Goldfish aren’t one of them. Let’s examine some of the fish’s sounds that are heard in oceans.
According to Marine science researcher, All fish are able to hear, and some are also able to make sounds using the mouth. However, they do not have vocal cords and therefore make bizarre noises!
Fish sounds can best be described as grunts and chirps and they can use these sounds to signal power or fear.
Fish make noises to communicate, mate or warn other fish about predators.
In fact, the first person to write about the vocalizations of fish was Aristotle around 2000 years in the past.
Fish can produce drumming sounds by vibrating their swimming bladder. Another sound it could produce sounds like the sound that you hear from metal rubbing against plastic.
Biologists have managed to capture these sounds using underwater microphones. It’s not easy since many species of fish shy away and remain at bay (or leave) when they encounter divers, so they needed to wait and be patient.
10. Rabbits
Scientific Name: Oryctolagus cuniculus
Class: Mammalia Diet: Herbivore
Rabbits, also known as bunnies, are tiny adorable creatures that reside all over the globe, with Antarctica being the only exception. They are well-liked indoor pets because of their affectionate personalities.
Did you know? Rabbit’s teeth will never stop growing. each year, their teeth increase five inches!
Bunnies don’t have vocal cords. This means that you won’t hear any sounds emanating from their mouths. But this doesn’t mean that the cute pants are totally silent.
If they were stressed or afraid Rabbits can make a variety of sounds. The most popular noises include hissing, growling, and snorting.
In the event that your pet rabbit is the majority of times quiet be assured that it’s completely normal!
9. Snakes
Scientific Name: Serpentes
Class: Reptile Diet: Carnivore
There are over three thousand snakes, and they are seen all over the world. There are many who are attracted to the snakes Their quiet presence is quite terrifying.
Did you know That Snakes are creatures with no external ears They also are able to hear the sound by absorbing earth vibrations!
Like the rabbits, snakes possess a tiny larynx as well as not having vocal cords. Contrary to many other species of animals, snakes aren’t able to produce sounds.
But, reptiles are capable of making certain kinds of sounds. The most well-known sound is a hiss. In addition, snakes could scratch or rattle their scales to create a sound.
However, there is a notable exception: that of the Pine snake. It is the only snake that has vocal cords. It is also a quiet species and uses its vocal abilities only occasionally.
As opposed to vocal communication, snakes gather chemical signals from their environment to recognize the presence of snakes.
8. Giraffes
Scientific Name: Giraffa
Class: Mammalia Diet: Herbivore
The Giraffes are mythical giants who are indigenous to the open grasslands and woodlands of Africa. They are the most extinct land animal and the biggest of ruminants.
Did you know Because of their enormous necks and legs giraffes are animals that can’t swim!
Giraffes might appear to be completely silent creatures However their sounds are not high enough for human ears to discern.
In addition to infrasonic communication Giraffes occasionally make grunts and hiss sounds in response to threats. In addition to the vocal signal, they utilize various forms of non-verbal communication.
The mates would also utilize their long necks to engage in a fight.
7. Snails
Scientific Name: Gastropoda
Class: Mollusca Diet: Herbivore, Carnivore, Herbivore
Snails have shelled gastropod species that can be found in a vast variety of ecosystems. Snails are night-eaters and prefer organic matter that is decaying.
Snails have up to 20,000 teeth, most than any other animal species!
We’ve all heard the phrase “slow as a snail” However, we’d like to include another meaning “silent as a snail”
Snails are not equipped with vocal cords and are completely silent. They will only sound only when eating or they are retracted into their shells.
But, the sounds are produced when doing mechanical activities, and not by producing sound intentionally.
6. Sloths
Scientific Name: Folivora
Class: Mammal Diet: Herbivore and Omnivore
Sloths are unusual animals that originate from rainforests of tropical Central as well as South America.
The diet of the three-toed sloth is entirely based on plants as do two-toed sloths, who eat insects and fruits, leaves, or even tiny mammals.
Have You known that Sloths are one of the slowest crawling animals in the world (1 foot per minute)!
Apart from being extremely slow creatures, They are also extremely quiet creatures too.
But, babies sloths can make loud squeaking sounds that are high-frequency when they are terrified or left alone.
Adults produce low-pitched sounds, however, it is also a sign that animals are scared or stressed.
5. Turtles
Scientific Name: Testudines
Class: Reptile Diet: Omnivore
Another peaceful animal that is distinguished in its shell, is the turtle. It is a native of a variety of oceans and continents, these animals traveled the globe in 220 million years.
Did You know Although they are widely regarded as mixed by people both tortoises and turtles are not the same animals!
Although they do not have vocal cords, certain turtle species have been known to produce high-pitched sounds.
But the sounds they make come from their lungs. These include grunts, hisses and moans, and honks.
When it comes to communication between each other, turtles usually use non-verbal communication, such as bitting, water splashing, and blinking.
4. Lizards
Scientific Name: Lacertilia
Class: Reptile Diet: Omnivore
There are over 6,000 lizard species, and they are found all over the globe, except for Antarctica. They range in size from a few inches to over 10 feet.
Did you know: Some lizard species have the ability to detach and regrow their tails!
Acoustic communication among lizards is uncommon. The most well-known sound is hissing. sound in all species, and typically, it is displayed as a warning signal.
But, geckos as well as some Iguanas have more sophisticated communication relating to courtship and territorial defense. The vocals can include barks, growls, and clicks.
3. Crabs
Scientific Name: Brachyura
Class: Phylum arthropods Diet: Omnivore
Crabs are ten-legged creatures that are distinguished by just a couple of claws. They are found in oceans but can be found in the land and in the water.
Do You Know? The biggest crab in the world is The Japanese crab (12 feet)!
Crabs are quiet animals but they have developed a unique method of communicating.
The method is known as stridulation It is a unique method of communicating. It involves pressing the claws against the legs to create sound.
2. Sharks
Scientific Name: Selachimorpha
Class: Chondrichthyes Diet: Carnivore
Sharks are among the most deadly fish species that are encountered in all water habitats all the way from the shallows to the deepest ocean areas.
There are about 500 different shark species, and none can produce any sound.
Do You Know? The largest fish on the planet is known as the Whale Shark!
Sharks are silent killers of the ocean. Equipped with special scales sharks can swim in total silence. This is among the main reasons that sharks are among the most formidable predators in the oceans.
The communication between sharks occurs by touching, smelling gaping, and electromagnetism.
1. Octopus
Scientific Name: Octopoda
Class: Cephalopods Diet: Carnivore
The last of our list of quiet animals are the octopuses.
They are unique and bizarre marine creatures that are distinguished by the bulbs in their heads and eight limbs.
Baby crabs eat sea stars, larval crabs, and copepods. The eating habits of adult octopuses are based upon crabs, snails, fish, and even claims.
Have You know: Octopus has a brain in each arm; in total, they have 9 brains
They are silent hunters and do not make any sounds.
In order to communicate with one another, octopuses use a diverse range of communication signals.
They’ll utilize their arms, body posture, and color changes as a way of interacting with others.
