14 Quiet Animals Who Are Silent or Make No Sound

There 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.

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!

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
