What are the bristles of a whale's mouth called?
Known as baleen, these bristles are made of a strong yet flexible protein called keratin—the same thing human hair and nails are made of—and are arranged in plates like a comb. When feeding, the whale takes a huge gulp of seawater and uses the baleen like a sieve to retain food in its mouth while pushing the water out through the gaps.
What is baleen in a whale's mouth?
Cross-section of jaw showing bone a, gum b, rigid plate c and frayed baleen hairs d and e Baleen is a filter-feeding system inside the mouths of baleen whales. To use baleen, the whale first opens its mouth underwater to take in water.
Do whales have teeth or teeth on top?
Toothed whales, such as sperm whales, have teeth and feed on prey including squid and fish. Meanwhile, baleen whales —such as humpback, blue, gray, and minke whales—have special bristles in their mouths instead of teeth and eat tiny prey such as plankton, krill, and small fish.
How does a whale swallow its prey?
It then partly shuts its mouth and presses its tongue against its upper jaw, forcing the water to pass out sideways through the baleen, thus sieving out the prey, which it then swallows. Whale baleen is the mostly mineralized keratin-based bio-material consisting of parallel plates suspended down the mouth of the whale.
What does a whale have in its mouth?
All baleen whales have baleen instead of teeth which they use to collect shrimp-like krill, plankton and small fish from the sea. These bristly baleen plates filter, sift, sieve or trap the whales' favourite prey from seawater inside their mouths.
What is the hairy stuff in whales mouth?
Baleen is the soft, hair-like structure on the upper mouth of whales, such as the humpback whale in this photo, which allows them to trap prey in their mouth.
Is a whales mouth filled with water?
An adult blue whale takes up to 10,000 gallons of water into her mouth at one time while she's eating. She doesn't drink all that water, though; the baleen in the whale's mouth filters the food and the whale pushes most of the water out.
Can you survive in a whales mouth?
Their mouths are big enough to hold a human. If they dive with you in there, you could suffocate. A lobster diver that found himself in a whale's mouth survived because he had scuba equipment to help him breathe. Two kayakers also ended up in a whale's mouth.
Can a whale swallow a human?
Despite occasional reports of whales scooping people into their mouths, it's incredibly rare—and for all but one species, swallowing a human is physically impossible.
Do whales sleep?
Observations of bottlenose dolphins in aquariums and zoos, and of whales and dolphins in the wild, show two basic methods of sleeping: they either rest quietly in the water, vertically or horizontally, or sleep while swimming slowly next to another animal.
Why do whales explode?
There have been several cases of exploding whale carcasses due to a buildup of gas in the decomposition process. This would occur if a whale decides to strand itself ashore.
Do whales get thirsty?
The answer is: they do not drink water like land animals do, as they don't risk dehydration from the sun. This goes for all the marine mammals like whales, dolphins, seals etc. The way they get water is through their food.
How do whales sleep?
Humpback whales are often found resting motionless on the surface of the ocean while sleeping. They cannot sleep for much longer than 30 minutes without risking lowering their body temperature due to inactivity. A very common assumption is that whales sleep with half of their brain 'shut off' and one eye closed.
Has anyone ever been swallowed by a whale and survived?
James Bartley (1870–1909) is the central figure in a late nineteenth-century story according to which he was swallowed whole by a sperm whale. He was found still living days later in the stomach of the whale, which was dead from harpooning.
Is it possible to live inside a whale for 3 days?
The man who disappeared for several days after he went overboard during bad storm has return to share his survival tale. The 56-year-old fisherman Luigi Marquez claims that a whale swallowed him. According to Marquez he stayed there for three days and nights.
What is the biggest thing a whale can swallow?

But it's all wrong the
Do barnacles hurt whales?
They don't harm the whales or feed on the whales, like true parasites do. Barnacles don't serve any obvious advantage to the whales, but they give helpful lice a place to hang onto the whale without getting washed away by water. Barnacles find the slow-swimming gray whale a good ride through nutrient-rich ocean waters.
Can you remove barnacles from whales?
As barnacles do not seem to cause any lasting damage to whales, it is not necessary to remove them. The only situation in which they must be removed is if there are too many barnacles clinging to whales, which can cause skin irritation.
Why do whales have bristles for teeth?
The bristles effectively keep the animals from escaping while allowing water to flow through them. Some scientists call baleen whales “filter feeders” because of the way they capture their prey and filter out the unwanted seawater and sediment. With the absence of teeth, baleen whales do not chew their prey.
Do whales fart?
Yes, whales do fart. Can you imagine the size and bubbles of a fart from the world's biggest animal, the blue whale? I'm yet to experience this, but I know of some lucky scientists who have seen a humpback whale fart. They tell me it looks like bubbles coming out underneath its body near the tail.
What is a whale's hair called?
Its hairy fringes are called baleen hair or whalebone hair. They are also called baleen bristles, which in sei whales are highly calcified, with calcification functioning to increase their stiffness. Baleen plates are broader at the gumline (base). The plates have been compared to sieves or Venetian blinds .
How do whales use baleen?
To use baleen, the whale first opens its mouth underwater to take in water. The whale then pushes the water out , and animals such as krill are filtered by the baleen and remain as a food source for the whale. Baleen is similar to bristles and consists of keratin, the same substance found in human fingernails, skin and hair.
What is the role of baleen plates in whales?
A whale's baleen plates play the most important role in its filter-feeding process. To feed, a baleen whale opens its mouth widely and scoops in dense shoals of prey (such as krill, copepods, small fish, and sometimes birds that happen to be near the shoals), together with large volumes of water.
What is whale baleen?
Whale baleen is the mostly mineralized keratin-based bio-material consisting of parallel plates suspended down the mouth of the whale. Baleen's mechanical properties being strong and flexible made it a popular material for numerous applications requiring such a property (see Human uses section). The basic structure of the whale baleen was characterized to be a tubular structure with a medulla hollow core enclosed by a tubular layer with a diameter varying from 60 to 900 microns, which had approximately 2.7 times higher calcium content. The elastic module in the longitudinal direction and the transverse direction are 270MPa and 200MPa, respectively. This difference in elastic module could be attributed to packing of the sandwiched tubular structure.
Why did the current change from teeth to baleen?
This occurred because the current kept warm ocean waters away from the area that is now Antarctica, producing steep gradients in temperature, salinity, light, and nutrients, where the warm water meets the cold . The transition from teeth to baleen is proposed to have occurred stepwise, from teeth to a hybrid to baleen.
Which whale has the longest baleen?
Some whales, such as the bowhead whale, have longer baleen than others. Other whales, such as the gray whale, only use one side of their baleen. These baleen bristles are arranged in plates across the upper jaw of whales.
Do mysticetes have teeth?
It is known that modern mysticetes have teeth initially and then develop baleen plate germs in utero, but lose their dentition and have only baleen during their juvenile years and adulthood. However, developing mysticetes do not produce tooth enamel because at some point this trait evolved to become a pseudogene.
What is special about a whale shark mouth?
Whale sharks are filter feeders with a diet mostly consisting of krill, plankton, and algae.
How do their “teeth” work?
Whale sharks have teeth, but they are vestigial and they don’t use them.
What is the only whale that can swallow a human?
Of the 90 known whale species on Earth, sperm whales are the only species with throats large enough to technically swallow a human.
What do whales eat?
Toothed whales, such as sperm whales, have teeth and feed on prey including squid and fish. Meanwhile, baleen whales —such as humpback, blue, gray, and minke whales—have special bristles in their mouths instead of teeth and eat tiny prey such as plankton, krill, and small fish.
Where do sperm whales live?
While sperm whales are widely distributed around the world, these deep-diving animals live mostly in the open ocean , and regularly spend time at depths of over 10,000 feet.
Why are whales so fearful of humans?
Instead, Deaville says, it’s whales that should be more fearful of us because of the “wide variety of man-made pressures and threats out there.”
How do humans harm whales?
Humans can harm whales through hunting, pollution, habitat destruction, entanglement in fishing nets, ship strikes, and more. Irresponsible tourist behaviors—such as getting too close—can also be distressing for whales.
Did the whale swallow the packard?
In Packard’s case, she says, he was likely “engulfed as opposed to swallowed” before the whale realized its mistake and immediately spat him out—likely a traumatic experience for both Packard and the whale, which was just trying to eat some fish.
Did humans end up in whales?
It’s not the first time that humans have purportedly ended up in a whale’s mouth: In 2020, kayakers were caught in the mouth of a feeding humpback in California, as was a tour operator in South Africa’s Port Elizabeth Harbour in 2019. Most famously, the Bible tells the story of Jonah, who was swallowed by a whale to save him from drowning. Even Pinocchio’s father Geppetto is swallowed by a whale in the classic children’s story.
What happens when a whale surfaces?
When a whale surfaces the first thing it does is expel all the remaining air to breathe in fresh oxygen. The whale has a nasal plug a little under the opening of the blowhole. This prevents water from getting into the trachea. So what comes out actually contains very little water. Mostly, what comes out it hot air.
What comes out of a whale's blowhole?
Picture yourself on a whale watching tour. Imagine the excitement and exhilaration of a whale surfacing right by your boat. You lean over to take a picture or give it a gentle pat, and it blasts your whole boat with a fountain from its blowhole.
Why do whales have a blowhole?
Unlike a human, a whale’s nose (blowhole) isn’t directly connected to the mouth. They have evolved a laryngeal plug that blocks the contents of the mouth from entering the lungs. This is important since it lets them eat without water entering their lungs and drowning them.
How to breathe in a person with a respiratory system similar to ours?
Since their respiratory system is so similar to ours you can basically try it out for yourself. Take a deep breath and hold it tightly. When you need to breathe exhale sharply through your nose, emptying your lungs in a quick blast. What comes out? Probably not just hot air.
What comes out of the nose?
Mostly, what comes out it hot air. The water at the top mostly turns into a mist, and some of the mucous lining from the nose comes out as well.
Where did the Hector's dolphin breathe?
A team in New Zealand observed a Hector’s dolphin that appeared to be breathing exclusively through its mouth. Upon closer inspection, they could hear the breathing sounds coming from its open mouth. Over the next few years, the same dolphin was witnessed practicing this behaviour by other teams in the area.
Is whale air bad for you?
Next to that, a little whale air isn’t so bad. The whale’s not going to give you a cold, and you won’t be coated in boogers (just a light misting). If you get up close to a whale, don’t worry about what’s coming out of the blowhole.

Etymology
The word "baleen" derives from the Latin bālaena, related to the Greek phalaina – both of which mean "whale".
Evolution
The oldest true fossils of baleen are only 15 million years old because baleen rarely fossilizes, but scientists believe it originated considerably earlier than that. This is indicated by baleen-related skull modifications being found in fossils from considerably earlier, including a buttress of bone in the upper jaw beneath the eyes, and loose lower jaw bones at the chin. Baleen is believed to have evolve…

Human uses
People formerly used baleen (usually referred to as "whalebone") for making numerous items where flexibility and strength were required, including traditional baskets, backscratchers, collar stiffeners, buggy whips, parasol ribs, switches, crinoline petticoats, and corset stays. It was commonly used to crease paper; its flexibility kept it from damaging the paper. It was also occasionally used in cable-backed bows. Synthetic materials are now usually used for similar purposes, especially p…
As a habitat
Baleen serves as a habitat for some species from the gastropod families Pyropeltidae, Cocculinidae, Osteopeltidae, and Neolepetopsidae.
