Man Vs Wild

These are the types of animals that do not communicate through their vocal cords or mouths.

Here’s a look at some truly amazing facts!

Let’s get down to it and see how and why these animals get through the day without making a sound.

We also have some types of animals that are super-quiet hunters and predators. They have the ability to surprise any animal because they are sneaky quiet.

But let’s start with some animals that don’t make a sound through their mouths.

These are the animals that don’t make a sound.






Let’s start by explaining that we’re talking about sounds an animal makes with its mouth.

I think all animals can make sounds when talking about the mechanical sounds they make when they move, eat or fight.

But we are talking strictly about calls and other sounds made by the mouth to communicate with other animals or express pain. We are talking about sounds made by the mouth.

Let’s look at some silent animals that do not or cannot make sounds.

The Jellyfish is completely silent


There is a good reason why jellyfish do not make sounds.

You probably know that you like swimming in the ocean. Jellyfish can be fun to watch, but some of them may tickle you. So it would be better if they weren’t completely silent. But they are %100 no sound.

Jellyfish are very simple and amazing sea creatures, and they belong to the list of animals that don’t even have a brain. This also means that they are incapable of generating any form of communication.

They just float around and feed.

Earthworms are also silent.

Earthworms do not communicate with each other by sounds.

So they usually use touch and taste to communicate. They are very good at sensing vibrations (in the ground), and when they feel the ground shake, they move upwards quickly. They do this to avoid getting caught by the enemy.

But after all, worms live most of their lives underground or under rocks and stones, so why wouldn’t they be quiet anyway. There’s no one to talk to underground anyway.


Sea urchins do not make any noise!

Sea urchins do not communicate with their mouths. In fact, they don’t even have a brain (like jellies).

Sea urchins are very simple animals that can only move and feed.

So there is no communication through its mouth. The only sound you hear from this animal is its tiny feet walking on small rocks at the bottom of the ocean (or in an aquarium).

Sea urchins eat algae off the rocks, and they can do this very quietly. But you may hear small scratching sounds if you are completely silent around it. This is what algae grinding teeth can do!


Do Fish Make Sounds?

most fish are quiet but some can make a few sounds

You might think that fish are generally completely silent.

But you would be wrong.

In fact, there are many species of fish that can make vocalizations. Your goldfish isn’t one of them, but let’s take a look at some of the fish in the ocean.

According to Shahriman Ghazal, a marine scientist at the University of Auckland, all fish can hear, and some can make vocalizations with their mouths. But they don’t have vocal cords, so they make strange sounds!

Fish calls are best described as squeaks and grunts, and they make these sounds to communicate and express dominance, fear, or pain.

Fish make noises to communicate, to mate, or to warn other fish of predators.

In fact, fish calls were first described by Aristotle more than 2000 years ago. A fish can make a drumming-like buzzing sound by vibrating its flipper.

The other sound fish can also make sounds more like plastic rubbing against iron or metal steel.

Biologists have also been able to record these sounds with underwater microphones. This is difficult to do because many fish are shy and go silent (or swim away) when they see divers, so they have to be patient and wait.

The vocal Pine Snake

Snakes are another category of animals that did not process vocal cords.

As you probably know, snakes make hissing and also produce a rattling sound to let you know they are approaching. The vocal cords do not produce this hissing sound.

But as with many rules, there are exceptions.

The Pine snake has local chords so that it can make several calls. But in most cases, they do not. They are quiet and silent like other snakes, and they don’t use their special abilities.
