People aren't the only ones who raise their voices at each other; fish can shout, too. After catching some blacktail shiners—little minnows characterized by a big black splotch on their tail fin—fishery biologists placed them in tanks equipped with underwater speakers to see if noisy conditions affect communication.
Mudskippers scream at each other when they are out of the water, according to a study published in a recent issue of the online journal PLoS ONE.
We may think of them as silent, but fish make many sounds that are rarely appreciated by the human ear. Clownfish chirp and pop by gnashing their teeth together. Oyster toadfish hum and blare like foghorns by quickly contracting muscles attached to their swim bladders.
Another way fish can make noise is called "stridulation". This is a sound made by rubbing bones, armour plates or teeth together. Examples of this are seahorses, which can produce popping sounds by rubbing the edges of their skull together, or some marine catfish which can "squeak" using specialised rays in their fins.
For a fish to scream it would need to feel pain, and they don't have the same pain system as humans.
The wild wriggling and squirming fish do when they're hooked and pulled from the water during catch-and-release fishing isn't just an automatic response—it's a conscious reaction to the pain they feel when a hook pierces their lips, jaws, or body.
“Fish do feel pain. It's likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
Fish don't have specialized vocal cords, larynxes or vocal folds. So one of the most common ways they make sound is through tribulation — rubbing two pieces of bony structure together, “like clicking their teeth or rubbing their pectoral fins against other structures to make cricket[-like] sounds,” says Looby.
For fish, whales and other marine animals, intense underwater noises from blasts can cause acoustic trauma and even death.
Yes, fish can hear you talk!
Sounds that are created above water typically do not carry enough force to penetrate the surface tension of the water, so talking on the boat or loud noise may not affect fish as much as your fellow anglers may want you to think. Your voice is unlikely to spook or scare fish away.
Scientists differ on the degree to which fish can have consciousness. Some researchers argue that they cannot have consciousness as their brain is simple, lacking a cerebral cortex, and they have little capacity for learning and memory, a very simple behavioral repertoire, and no ability to experience suffering.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
Yes, fish experience both physical and emotional pain. Scientists say that it's likely a different type than what humans experience, but it's pain nonetheless. Fish have nerve cell endings called nociceptors, which alert their bodies to potential harm such as high temperatures, intense pressure, and harmful chemicals.
Gulf corvina are able to produce such a powerful noise because their swim bladder, a gas-filled organ in the abdomen, is surrounded by “sonic muscles,” Rowell tells Guarino of the Post. The muscles drum against the bladder when the fish contract their abdomens, resulting in the beehive-like sound heard by researchers.
Gulf corvina have air sacs called swim bladders tucked within their bellies. "Sonic muscles," Rowell said, encircle the swim bladders. Marine biologists described Gulf corvina as the "loudest fish ever documented".
Anglerfish
Commonly known as “Sea Devils,” Anglerfish are the archetypal horror of the deep. They lurk on the bottom, waiting for unsuspecting prey to come their way. Their mouths are so big they can eat fish almost as big as they are. Anglerfish inhale their meals whole.
Exposure to intense sounds can cause a permanent or temporary hearing loss. Some anthropogenic sounds may cause temporary threshold shift (TTS), depending on a number of variables including the frequency and intensity of the sound, duration of exposure, etc.
Researchers from Keio University in Japan have studied the effects of playing music for fish kept in indoor glass tanks and outdoor koi ponds, and one of the conclusions was that fish can not only hear music but also react to harmonious sounds.
Goldfish are very sensitive to vibrations in the water. Tapping on the side of the tank – or making a loud noise near your goldfish tank – will cause strong vibrations and startle your fish.
A new Cornell study finds that fish are far more likely to communicate with sound than generally thought – and some fish have been doing this for at least 155 million years. “We've known for a long time that some fish make sounds,” said lead author Aaron Rice, a researcher at the K.
Fish aren't known for their impressive singing ability, although some can grunt and hum, yet singing originated in lungfish, according to new research that also determined how songbirds consistently produce melodious, sweet tunes.
The sing-off begins when the sun goes down. Every night off the coast of Bocas del Toro, Panama, Bocon toadfish start calling from their burrows, trying to win over females by showing off their vocal talents and drowning out the competition. If you've never heard of the singing toadfish, you're not alone.
Here is a news article I found on the topic: Worms on a Hook Don't Suffer? OSLO (Reuters) - Worms squirming on a fishhook feel no pain -- nor do lobsters and crabs cooked in boiling water, a scientific study funded by the Norwegian government has found.
Fish have gills that allow them to “breathe” oxygen dissolved in the water. Water enters the mouth, passes over the gills, and exits the body through a special opening. This keeps an adequate amount of water in their bodies and they don't feel thirsty.
Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.
