Do whales swallow seawater?
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. … Whales (whether they are toothed whales or baleen whales) do not voluntarily ingest water.
Does whale feed milk?
Whales are sea mammals and possess the typical characteristics of all mammals. This means that they have mammary glands and produce milk to feed their young.
How do blue whales feed?
Blue whales are the largest animals ever to live on our planet. They feed almost exclusively on krill straining huge volumes of ocean water through their baleen plates (which hang from the roof of the mouth and work like a sieve). Some of the biggest individuals may eat up to 6 tons of krill a day.
How do whales produce phytoplankton?
In death whales carry the tons of carbon stored in their massive bodies down to rest on the seafloor where it can remain for centuries. Whale excrement fertilizes the ocean producing large phytoplankton blooms that absorb enormous amounts of carbon dioxide.

What do krill feed on?
phytoplanktonAntarctic krill are filter feeders that eat tiny phytoplankton (pelagic algae). They use their small hair-like legs to filter out these microscopic algae that bloom in the nutrient-rich waters around Antarctica. These blooms are densest at the ice edge so Antarctic krill are often also densest near that system.
How Giant Creatures Eat Tiny Meals: 5 Fabulous Filter Feeders
Why do whales consume plankton?
Food webs are often pretty short which confused many scientists for a long time. Ever wonder why such a large whale feeds on such small planktonic organisms such as krill? … However the primary means for determining what marine organisms eat is to study their stomach contents which is exactly what Reilly et al. See also what is found in the mesosphere
How do whales eat krill?
In fact krill – about two inches long –make up the majority of their diet. Blue and humpback and other baleen whales are filter feeders. They take in huge gulps of seawater dense with krill straining out the water though their baleen and then swallowing their catch.
How do blue whales survive on plankton?
In a nutshell whales some of the largest creatures on the planet can survive by eating krill because they eat so many of them.
How do whales act as carbon sinks?
Whales accumulate carbon in their bodies during their long lives. When they die they sink to the bottom of the ocean each great whale sequesters 33 tons of CO2 on average taking that carbon out of the atmosphere for centuries. A tree meanwhile absorbs only up to 48 pounds of CO2 a year.
Can a whale swallow a human?
Whales in general are not capable of swallowing a human being and therefore will not eat you. However there is a species of whales that does pose a legitimate challenge to that general theory: sperm whales. See also what is the importance of estuaries
How do whales eat without swallowing water?
Marine mammals feed entirely underwater. Seals and dolphins can hunt catch and swallow food beneath the water. Marine mammals make sure that they capture their prey and not swim away before swallowing. They do this by sucking the food deeper into the mouth by pulling back their tongue once the prey is in their mouth.
Has a sperm whale ever killed a human?
white as wool”. Legend has it that it killed 30 men and was covered in scars and punctured with spears from previous attempts to harpoon it before eventually being slaughtered in 1838. Sometimes described as Leviathans sperm whales truly are creatures of mythical proportions.
How do whales impact the biosphere?
The way that whales feed poo migrate and dive between the surface and the ocean depths (known as the ‘whale pump’) circulates essential nutrients throughout the ocean. This in turn supports healthy marine ecosystems and the growth of phytoplankton which locks in a massive amount of carbon from the atmosphere.
How many nipples does a whale have?
How Many Nipples Whales Have? Just like humans whales have two nipples. And being the largest animal they also have the largest glands. That is 5 feet long and weighs around 115 kg equivalent to 250 pounds.
How do whale sharks feed?
Whale sharks are filter feeders and can neither bite nor chew. … Although its mouth can stretch to four feet wide a whale shark’s teeth are so tiny that they can only eat small shrimp fish and plankton by using their gill rakers as a suction filter.
Humpback whales have magnetic material in their brains that may help them navigate. Each year whales migrate from Hawaii to the northern Pacific coast and back.
Is a blue whale a sperm whale?
That distinction goes to the blue whale (Balaenoptera musculus) the largest animal on Earth. … The sperm whale (Physeter macrocephalus) on the other hand may not be the biggest whale but it has the biggest brain to have ever existed on Earth . A comparison chart of whale sizes helps put it all in perspective!
Do whales eat plankton or krill?
Food Preferences and Resources Right whales eat zooplankton (animal plankton). Their finely fringed baleen is able to strain from the water copepods (a type of small crustacean) and other small zooplankton. Krill (a family of small shrimplike crustaceans) and copepods are major components of a right whale’s diet.
Do all whales eat plankton?
As it turns out most whales don’t eat large prey. … They feed on small plankton and krill which drift with the nutrient rich waters where the whales live. Not all whales feed on plankton however. Sperm whales for instance feed on animals like giant squid in the deep waters of the ocean.

Why do whales feed on krill?
This range seems to reflect the energy density of the food—whales need to eat more krill to get the same energy as they would from a smaller amount of fish. “As large baleen whales get bigger the anatomical machinery that allows them to eat also gets relatively bigger ” Goldbogen said.
Half a million calories in a mouthful – filter feeding
What do whales provide for plankton?
Because whales can’t “poop” under pressure they take their bathroom breaks at the ocean’s surface and by doing so supply phytoplankton with life giving nutrients like iron nitrogen and phosphorus. Whales are the ocean’s gardeners tending the forest of phytoplankton on which we all depend.
How do whales help produce oxygen?
Whales accumulate carbon in their bodies during their long lives some of which stretch to 200 years. … Wherever whales are found so are phytoplankton. These tiny creatures produce every second breath we take by contributing to at least 50 per cent of all the oxygen in our atmosphere.
How do Humpbacks feed?
Humpback whales filter-feed on small crustaceans (mostly krill) and small fish. They use several techniques to help them herd corral and disorient prey and that can include using bubbles sounds the seafloor and even their pectoral fins.
How do whales filter plankton?
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.
Do men have breasts?
The truth is that boys and girls men and women all have breast tissue. The various hormones in girls’ and women’s bodies stimulate the breast tissue to grow into full breasts. Boys’ and men’s bodies normally don’t make much of the breast-stimulating hormones.
Do whales Bellow?
One whale blows a ring of bubbles below the fish to contain them. Another whale dives deep and bellows a loud feeding call. Then all the whales surface within the bubble “net ” mouths agape and teeming with fish!
What do sperm whales feed on?
Behavior and Diet Because sperm whales spend most of their time in deep waters their diet consists of species such as squid sharks skates and fish that also occupy deep ocean waters. Sperm whales can consume about 3 to 3.5 percent of their body weight per day.
Do whales fart?
Yes whales do fart. … 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. That’s where the whale bum is — the smellier blowhole.
How Does A Whale Feed On Zooplankton?
A right whale “grazes” by swimming slowly through swarms of small zooplankton (animal plankton) with its mouth open. At the surface this has been termed “skim-feeding” but right whales also feed under water. Water–and zooplankton–enter a right whale’s mouth through a gap in the front baleen plates.
Are Whale sperm bigger than human sperm?
Amazing whales have some of the smallest sperm of all mammals. They vary from 50-75 microns whereas human sperm are 40-90 microns long. It is thought that whales have such small sperm because the female reproductive tract is so large that having longer sperm doesn’t give a male any extra advantage.
Who eats killer whales?
Killer whales are apex predators which means they have no natural predators. They hunt in packs much like wolves which are also at the top of their food chain.
Do krill eat zooplankton?
Krill are considered an important trophic level connection – near the bottom of the food chain. They feed on phytoplankton and (to a lesser extent) zooplankton yet also are the main source of food for many larger animals.
How do minke whales feed?
Minke whales feed by side-lunging into schools of prey and gulping large amounts of water. Sea birds attracted to the concentrated prey just below the surface are sometimes associated with minke whale feeding and foraging. See also What Is Political Boundaries?
How do whales feed?
They are carnivores that love to eat fish. Their teeth are not used for chewing only for capturing and holding on to the food. Baleen whales feed by filtering or straining food from the water. … They then push the water out past their baleen plates and the food gets trapped inside to then swallow.
