Animals Without Ears (With Pictures & Hearing Facts)

For the majority of animals, hearing is one of their most crucial inherent capacities. Hearing is a universal warning of danger, and without it, wildlife would be impossible. Now here comes the question of whether there are animals without ears.

But what about animals without ears? Numerous species of animals exist that don’t have ears but can nevertheless hear sounds. For example, not all fish and birds have external structures. Still, they can hear.

However, in this article, we are going to talk about animals without ears. We will see what different techniques these animals use to gather the sounds around them and which ones have the greatest sense of hearing.

Animals Without Ears

Salamander

Salamanders are first on the list of animals without ears. Salamanders are slender-bodied, short-legged, nocturnal amphibians typically found in moist habitats. There are more than 500 different species, some entirely aquatic, others occasionally moving into the water.

These lizard-like animals do not have ears, but they can still detect wind sounds. However, salamanders respond more to ground vibrations than to airborne sounds.

According to Wikipedia, salamanders pick up sounds from the ground with their limbs. These vibrations are then transmitted to their inner ears, allowing salamanders to pick up sounds.

Turtles

Many people believe that turtles cannot hear because they lack an external ear. Although turtles rely primarily on other senses, they can hear sounds.

If we compare the hearing of turtles with humans, they have very less hearing ability. Actually, turtles only react to loud noises.

Turtles are almost unable to detect low-frequency sounds. However, they can hear much better sounds that contain higher frequency tones.

When we talk about underwater hearing, the hearing capacity of turtles is much higher than on the surface.

Snake

When we talk about animals without ears, snakes must be mentioned. These legless animals have good hearing despite having no external ears.

Snakes can hear sounds through vibrations on the ground. Snakes have eardrums attached to their jaws that allow them to pick up sounds from the ground.

However, snakes cannot hear high-frequency sounds because these sounds come from the air. As a result, sounds from the ground are what snakes primarily rely on.

Recent studies show that most snake species can hear sounds in the range of 80 to 600 Hz. For comparison, we humans can hear frequencies in the range of 20 to 20,000 Hz.

Frog

Frogs are known to make a variety of vocalizations during courtship. But how well can these amphibians hear without ears?

Frogs have eardrums and inner ears despite not having external ears. Not only can they hear sounds, but they can hear up to 38 kHz (the highest of any amphibian).

Humans converse typically at 2 to 3 kHz and have a hearing range of up to 20 kHz.

A frog’s eardrums are connected to its lungs. Because of this, frogs can produce so much sound without damaging their eardrums.

Spiders

Another animal without ears that can hear is the spider. Recent studies have shown that these arachnids also lack eardrums. So how well can they hear?

Spiders use hair receptors on their legs to pick up sounds.

Until recently, scientists believed that spiders were unable to pick up sounds that travel through the air. However, further studies have confirmed that spiders can hear more than just surface sounds.

Although spiders can hear lower frequency sounds more accurately than higher frequencies.

Worms

Despite having no ears, insects can detect sounds through their bodies. They pick up sounds by sensing ground vibrations near them.

Insects are able to detect vibrational sounds from within the soil surface or directly from the ground. These vibrational sounds are usually warning signs of potential predators lurking nearby.

Even insects do not have eyes. But instead, have light receptors, which help them distinguish between day and night.

Harp Seals

Despite lacking external ears, harp seals are animals with a well-developed sense of hearing. Especially underwater.

When submerged, the seals’ hearing abilities are astounding, with frequencies exceeding 60,000 Hz. On the other hand, when seals are beached, they have heard similar to ours.

Although their hearing is more developed for underwater use, harp seals have an excellent directional hearing in both water and air.

Crabs

Crabs are one of these animals without ears that don’t have very good hearing. They can only hear low- to mid-frequency sounds, and only at close range.

When detecting sounds, crabs use antennae and sensory hairs on their legs to pick up vibrations.

In general, crabs rely mainly on their sense of smell and are not very sensitive to sounds. In fact, crabs probably do not hear high-frequency sounds and can only react to low frequencies.

Crocodiles

Speaking of animals without ears, the last species of crocodiles must be mentioned. These fearsome predators possess keen hearing despite having no external ears.

Crocodiles have slits just above their eyes. These openings lead to the inner ear. The inner ear is responsible for the great hearing of crocs.

However, when submerged, these holes close to prevent water from entering the ears. As a result, while underwater, crocodiles rely more on water vibrations than actual sounds, as on land.

Alligator hearing is most responsive to sounds in the 100 to 3000 Hz range. However, some species can detect sounds with frequencies above 8000 Hz!

According to LiveScience, a crocodile’s hearing is so sharp that it can hear its baby’s voice from inside its egg.

Last words on animals without ears

Everyone on the planet can hear. We have seen that even animals without ears somehow find a way to hear sounds.

However, hearing thresholds (frequency) can vary significantly between animals depending on the importance of hearing for survival.

Either way, hearing is an important survival sense, and without it, the world would be a different place.
