How do aquatic life and birds hear sound?

Some aquatic birds possess auditory adaptations for hearing underwater. For example, murres and auks have a special structure that creates a barrier over the external ear opening (birds do not have external flaps, or pinna). Penguins have active muscular control of their ear opening.

How do birds hear sounds?

Birds do have ears, but not in the conventional sense. ... Instead, they have funnel-shaped ear openings located on both sides of their heads that are usually positioned just behind and slightly below the eyes, according to BirdNote. These openings are covered with specialized soft feathers known as auriculars.

How do aquatic animals hear?

Changes in rate, pitch, and/or structure of sounds communicate different messages. ... By emitting clicks, or short pulses of sound, these marine mammals can listen for echoes and detect objects underwater. This is called echolocation. Some whales and dolphins use echolocation to locate food.

Can animals hear underwater?

Hearing is the detection of sound. Both modern land mammals, including humans, and marine mammals evolved from ancestors that had air-adapted ears. ... Some marine mammals that live exclusively in water, like whales and manatees, hear very well in water but hear poorly, if at all, in air.

How do animals use sound?

Sound can be used for more than just communication. Many animals such as bats, whales, and even some shrews and birds use sound for navigation and hunting, as well as communication. They do this by using echolocation, which is a technique that uses reflected sound to determine where objects are.

How do birds hear answer?

How do birds hear? Ans- Birds have tiny holes on both sides of their head covered with feathers. They help the bird to hear. ... Ans- Lizard has tiny holes on both sides of head to hear.

How do fish hear underwater?

As such, aquatic animals such as fish have a more specialized hearing apparatus that is effective underwater. Fish can sense sound through their lateral lines and their otoliths (ears). Some fishes, such as some species of carp and herring, hear through their swim bladders, which function rather like a hearing aid.

How do dolphins hear underwater?

Dolphins use small ear openings on both sides of their heads to listen to or hear sounds. ... To hear sounds underwater, they make use of their lower jawbone, that conducts sounds to their middle ear.

How do seals hear underwater?

Seals have a well-developed sense of hearing that is specialized for underwater acoustics. ... Seals are able to respond to sounds from 1 to 180 kHz when underwater. In the air, hearing ability is only from 1 to 22.5 kHz.

How do aquatic animals communicate in water?

Marine animals aren't big on body language. Instead, they use sound to communicate. Some use sound to hunt, engaging echolocation to find and sometimes to stun their prey. Sound travels differently through water than it does through air, but water serves as an effective sound-carrying medium.

How do animals produce sound?

Mammalian vocalizations are produced by the actions of the larynx, a set of tissues located in the throat. The larynx contains folds of tissue called the vocal cords (also called vocal folds), which vibrate as air passes from the lungs into the oral cavity (also called the mouth).

Do dolphins make sounds underwater?

Dolphins produce sounds differently in air and underwater. Wild dolphins mainly make sounds underwater, although they have been known to emit high-pitched whistles both under the water and above the surface when in distress.

How do bats hear?

They produce sound waves at frequencies above human hearing, called ultrasound. The sound waves emitted by bats bounce off objects in their environment. Then, the sounds return to the bats' ears, which are finely tuned to recognize their own unique calls.

How do whales hear underwater?

How do whales and dolphins hear? Whales and dolphins do have ears but they don't have external sticky out ears like ours to funnel sound as they need to be streamlined for life in the water. Their ear canals are not open to the outside. Instead, they generally hear sounds through special structures in their jawbones.

How can animals hear without having ears?

Invertebrates don't have ears; they use other organs to recognize sound waves. Insects may not have ears, but they have tympanal organs that give them superior hearing to humans. Hair helps bugs detect sound; spiders and cockroaches have "hearing hairs" on their legs and the caterpillar has them the length of his body.
