Their aural abilities are at their best when they’re swimming underwater. But the intriguing fact about these creatures is that even though they don’t have any external ear flap, they have excellent hearing abilities. They belong to the family of pinnipeds, and they’re excellent hunters. ![]() The harp seals or ‘true seal’ found in the frigid waters of the Russia, Norway, Greenland, and Canada fall into the category of animals that don’t have external ears. The only difference is that they aren’t as well developed as other creatures without ears. These are sounds that the creature usually makes to ward off predators.īut if it can’t hear the sounds, then how is it making the sound? Thus, snakes do hear specific frequencies of sounds, and this is done with the help of their middle ear bone. Hence, it would be entirely wrong to say that snakes are deaf and can’t hear anything.įor example, a study carried out by experts found that a few different pythons can listen to sounds of frequency ranging from 80 and 160 Hertz.īut you do know that snakes make hissing sounds. It’s common knowledge that snakes respond to vibrations, and it’s the vibrations that these creatures use to ‘hear.’īut the existence of a middle ear bone allows snakes to listen to a narrow range of frequencies. These creatures don’t have any ear-like structure that can be considered outer ear or middle ear and if you observe snakes closely, you’ll find no breaks in their scales.īut they do have something like a middle ear bone that connects the middle ear to the jaw bone. Snakes are another category of creatures belonging to the reptilian family that doesn’t have ears. So yes, a tortoise doesn’t have ears like other animals, especially mammals, but that doesn’t compromise its hearing. If a tortoise feels a threatening or dangerous vibration, it’ll quickly recede into its shell and stay there until it’s sure there is no danger. If its sense of smell helps a tortoise forage for food, its excellent hearing through vibrations helps the tortoise defend itself from predators. They use vibrations to protect themselves against potential dangers. In reality, both turtles and tortoises are pretty sensitive to sound. However, don’t think that the lack of an external ear will prevent the tortoise from hearing sounds. Tortoises don’t have ears primarily because the external outgrowth, which can be termed as the ‘ear of a tortoise,’ is entirely hidden by a scale. Tortoises don’t have ears and if you observe closely, you won’t see any organ for hearing on a tortoise because the exact location of the ears is behind its eyes and just above the jaws. Tortoises can be distinguished from other reptiles thanks to the shells on their backs but do they have ears? Have you noticed the quick movements of the head of a bird? This is when they’re trying to identify a sound and develop their response to it.īirds can use their heads to screen the sound coming from one angle, while sound waves traveling from the other direction can also elicit a reaction from the bird. Instead, birds without external ears listen to sounds that are coming from different directions through their head since this action allows them to transform sound waves in a manner that they can hear as if they had external ears. ![]() ![]() But without any external ears, birds can’t do this. In mammals, the external ears will divert the sound waves to the middle ears, translated to mechanical vibrations. If you compare the hearing capacity of mammals and birds, the first difference you’ll come across is that mammals have external ears. This means they can identify whether the sound is coming from above or below them. However, that doesn’t mean birds can’t ‘hear.’ Avian creatures like birds can distinguish sounds through a tiny opening on the sides of their head. BirdsĪ good majority of bird species don’t have external ears and you’ll never come across a bird that has ears as mammals do. ![]() FAQ Roundup Here are seven animals that don’t have ears.Here are seven animals that don’t have ears.
