Are you wondering ‘Do sharks make noise?’…Unlike their noisy Whale neighbours, sharks do not have organs that produce sound. Instead, their skin is altered so that they can glide through the water in eerie silence. However, there are reports of sharks in New Zealand barking like big dogs.
What Noise Do Sharks Make?
Sharks don’t make any noise underwater. Unlike their noisy neighbours, they have no sound-producing organs. Their scales are modified so that they can glide through the water in eerie silence. Sharks are so attuned to the great oceanic opera that they are, by and large, the silent hunters par excellence.
The pioneer of underwater exploration Jacques Cousteau called the ocean ‘the realm of silence, the world of truth.’
Whales sing haunting songs, dolphins yawn and click, snapping shrimp crackle and castanet and teleost fish generate all sorts of murmurs, growls, grunts, croaks, buzzes and clicks. Sharks are less attuned to the great oceanic operas.

Do Sharks Bark Like Dogs?
In New Zealand, there are reports of a type of shark barking like a big dog. It is known as the Draughtboard Shark (Cephaloscyllium isabellum) and New Zealand fishermen of this species know it is a noisy creature. Nobody knows exactly how they manage to bark.
A lot of people admire sharks because no matter what they do, they look cool. But no matter how cool they are, sharks are not immune to the occasional loud burp.
Do Sharks Make Noise Out Of Water?
Trapped in a net or hook line and pulled to the surface, the shark is inflated with air and water. The cardiac sphincter makes its stomach airtight. As it relaxes, the trapped air flows explosively through the stomach of the sharks, creating a hoarse bark. The shark relieves gastric pressure through the heart muscle, which works in such a way that the term is no longer quite so refined.
But I think there’s something deeper behind it, too, namely how deep the sound can get.
Like its closest relatives, the balloon shark (Cephaloscyllium sufflans) inflates like a puffer fish when threatened by a potential predator. In an underwater attack, the sharks pump water into the front of their stomach, increasing its diameter by up to three times. This water prevents the escape of the shark stomach by a muscle ring, the heart muscle sphincter. When the danger is over, the inflated shark loosens the spine and lets a sip of water gush from the stomach into the mouth. This sudden increase in size is enough to frighten and intimidate predators.
