Whales swim forward by flexing their tails up and down, instead of side to side as with most fish. To change direction, they move their flippers, similar to the way an airplane steers (read How Sharks Work for details). The dorsal fins, if present, serve to stabilize the whale’s body as it swims.
How do whales propel themselves through the water?
All whales propel themselves with up-down undulations of their large tails, an economical motion equivalent to the side-to-side oscillations of fish. The swimming mechanics of dolphins and smaller toothed whales have been observed in captive animals, but the largest whales cannot be studied in tanks.
How do whales not drown?
To avoid drowning during sleep, it is crucial that marine mammals retain control of their blowhole. The blowhole is a flap of skin that is thought to open and close under the voluntary control of the animal.
How do whales not choke on water?
When the whales lunge feed, the “oral plug” blocks the channel between a whale’s mouth and its pharynx—the entrance to the respiratory and digestive tracts—so the animal doesn’t swallow or aspirate any water.
Do whales ever drown?
Whales do not purposely drown themselves. However, if they get caught in a net and are unable to surface, they will drown. Beached whales may face a similar predicament. As tides rise, water may cover and enter the whale’s blowhole, causing it to drown before the water becomes deep enough for it to swim away.
Why do whales like to jump out of the water?
The simplest explanation for a whale jumping out of the water appears to be sociality or alertness. Which one of those, depends on the context. Killer Whales are highly social animals, and are composed of multiple family groups, so when related groups meet up this makes breaching more likely.
Can blue whales jump out of the water?
For mammals that can weigh anywhere between 12,000 to 400,000 pounds (depending on species), it can be quite a shock to learn that whales can jump. As their notably long and large bodies make their way to the surface of the water, they propel themselves up and above it, almost hanging in midair for a split second.
Do whales sleep underwater?
If asked, do whales sleep underwater? The answer is simple, YES they do. Their bodies shut down but only half of their mind stays at rest so that they conscientiously remember to breathe. Breathing near the surface where whales sleep allows them to breathe more conscientiously, meaning each and every breath counts.
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?
Do whales drown when they get old?
Yes, whales die of old age. Whales live a lot longer than most mammals, but each species of whale lives for a different amount of time. Some of them even have longer lifespans than humans.
Can a whale swallow a human?
Though a humpback could easily fit a human inside its huge mouth—which can reach around 10 feet—it’s scientifically impossible for the whale to swallow a human once inside, according to Nicola Hodgins of the Whale and Dolphin Conservation, a U.K. nonprofit.
Do whales swallow the water?
But then, how can whales get their water? Baleen whales do swallow a bit of water when they feed because they engulf large quantities of food (krill or fish) at a time and end up ingesting some seawater in the process.
Do whales ever get water in their lungs?
This is how water and pollutants can enter the animals’ respiratory tracts, scientists conclude. A humpback whale spouts water from its blowhole. New research shows the blowhole isn’t as protective as scientists had thought, and water and pollutants may be getting into whales’ lungs.
How many whales drown per day?
Over 800 slow deaths each day These animals — more than 800 every day of the year — died horrible deaths.
What do whales do at night?
Sleep. Many whales and dolphins sleep during the night. Whales, unlike humans who are involuntary breathers, must decide to take each breath. Accordingly, whales cannot spend long periods underwater without surfacing.
How many whales drown a day?
“Almost one thousand whales, dolphins, and porpoises die every day in nets and fishing gear,” said Karen Baragona, of the WWF species-conservation program. The new report will be submitted to the International Whaling Commission (IWC) at its annual meeting next week in South Korea.
How do whales see humans?
How do whales see humans? To them, everything is bright,” explained Fasick. This means that anything that looks blue or green to the human eye is invisible in the water to whales. The one color that whales can see as a dark shape in their bright, watery environment is red.
Why do whales hit their tails on the water?
Whales slap their tails as a means of communication, to warn away predators or other males, and to impress a potential mate. Different species of whale lobtail differently. Humpback whales will lobtail repeatedly. They will raise their tail back and forth many times to slap the water.
Why do whales come to the surface?
Whales are mammals, so they need to come up to the surface to breathe air. They breathe through “nostrils” on top of their heads called blowholes. When a whale surfaces to fill its lungs with fresh air, warm air escapes from its blowhole.
How big is a human compared to a blue whale?
Weight. The blue mammal is also incredibly heavy: 170+ tonnes, in fact. This is over 4 times larger than a sperm whale, and over 2,400+ the size of a human. Some blue whales are estimated to be as large as 190 tonnes.
Which whales breach the most?
Breaching is when most or all of the whale’s body leaves the water. Humpback whales can use their powerful fluke (or tail fin) to launch themselves out of the water. And while many other whale species breach, humpback whales seem to breach more frequently.
Why do whales sleep upright?
But Why Do Sperm Whales Sleep Vertically? Sperm whales sleep vertically to replenish their oxygen supply when needed and to stay alert to potential threats.
Can dolphins fall in love humans?
Dolphins in Love
In several surprising instances, dolphins have also shown loving emotions towards humans. The most fascinating of these examples is that of Margaret Howe and the bottlenose dolphin Peter. In the 1970s, Howe was conducting research with Peter in an attempt to teach the dolphin to communicate in English.
Do whales eat sharks?
These marine mammals have been known to attack and eat everything from small fish and turtles to squid, seals, sea lions, and even large whales. Killer whales also hunt, attack, and eat sharks.
How does a sperm whale sleep?
According to Nature, sperm whales likely choose between two types of sleep: full sleep while drifting at the surface, and half-sleep, depending on their needs.
Can spiders fart?
Since the stercoral sac contains bacteria, which helps break down the spider’s food, it seems likely that gas is produced during this process, and therefore there is certainly the possibility that spiders do fart.
Where are the nipples on a whale?
Whales and dolphins do not have external nipples, instead their nipples are enclosed within mammary slits. Upon stimulation of the calves nudging, the nipple is exposed and the calf positions itself such that the nipple is at the gape of the calf’s jaw for feeding.
Do whales pee in the ocean?
How Much of the Ocean is Whale Pee (And Worse)? – YouTube
Why do whales explode?
A decomposing whale carcass generates gases which build up inside their stomach and large internal organs. This then causes them to expand, but whale skin and blubber are tough so the gases become trapped inside, according to National Geographic.
Can a whale survive on land?
Whales can only survive a few hours on land. They breathe the air just fine. The problem is that their fat holds in too much heat. When the water is not there to absorb the heat, they die.
How do whales give birth?
Because whales are mammals, their calves grow inside their mothers and are born through live births. During the whale birth process, calves will emerge fins first. The size of a whale calf will depend on the size of the mother, but generally speaking you can expect it to be about ¼ the length of the mother.
Was Pinocchio in a whale?
In the 1940 Walt Disney film Pinocchio, the Dogfish is named Monstro (which is Portuguese, Esperanto, and archaic Italian for “monster”) and is portrayed as a terrible sperm whale with massive jaws, both of which have sharp teeth, and a grooved underside like a rorqual.

Why is it called a sperm whale?
They are named after the waxy substance—spermaceti—found in their heads. The spermaceti is an oil sac that helps the whales focus sound. Spermaceti was used in oil lamps, lubricants, and candles.
Would a whale spit you out?
The esophagus on nontoothed whales is too small to actually swallow a human but they could wrap their mouth around a large object and then spit it out.
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 get rid of salt?
Many marine mammals have specialized organs called reniculate kidneys with multiple lobes, increasing their urine-concentrating efficiency beyond that of humans. These animals can handle high concentrations of salt in seawater without becoming dehydrated by salt buildup, as humans would.
Do whales poop and pee?
Humpback, gray and blue whales can travel halfway around the world from their feeding to their calving grounds, the longest migrations of any mammal. By peeing, pooping and giving birth near the surface, whales transport literal tons of nutrients across huge distances and depths, Roman said.
How does a whale breath under water?
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. They breathe through nostrils, called a blowhole, located right on top of their heads.
Can dolphins drown?
Can Dolphins Drown? It is actually rare for a marine mammal to “drown,” as they won’t inhale underwater, but they do suffocate from the lack of air.
How long can whales hold their breath underwater?
The average whale can hold its breath for about 60 minutes. The Sperm whale can hold its breath longer than the average whale, for about 90 minutes. The whale that can hold its breath the longest, however, is the Curved Beak Whale, who can take long dives underwater for about 138 minutes!
