Concerning the Species – The blue whale is the biggest mammal that has ever been known to have existed on our planet. They obtain practically all of their nutrition from krill, which they extract from the water by forcing it through the baleen plates on their jaws (which hang from the roof of the mouth and work like a sieve).
It’s possible that the largest people consume as much as six tons of krill in a single day. There are blue whales in every ocean on the planet with the exception of the Arctic Ocean. There are now five different subspecies of blue whales that are recognized. Blue whale populations are growing over the world, despite the fact that their numbers are only a small fraction of what they were before contemporary commercial whaling dramatically cut their numbers in the early 1900s.
At this time, the two most significant dangers that blue whales face are being hit by ships and being entangled in fishing gear. Blue whale populations all throughout the world need to be preserved and rebuilt, and NOAA Fisheries and its partners are committed to doing just that.
How does the whale feeding?
What kind of food do baleen whales consume? – Baleen whales, in contrast to toothed whales, do not have any teeth in their mouths. Instead, they are equipped with bristles that, much like the bristles on a comb, may be used to create a net that can be used to catch animals.
- It is well known that baleen whales engage in filter feeding, which is a distinctive way of hunting.
- In the process of filter feeding, a baleen whale would approach its meal while swimming with its mouth open.
- After the whales have successfully captured their prey, they will next seal their lips and use their tongues to expel any surplus water.
Their bristles prevent the whale food from falling out of the mouth of the whale. After this, the prey is consumed in its entirety. When feeding, baleen whales may either swim through schools of fish and other kinds of whale food, or they will skim the surface of the water with their mouths open in order to collect anything that is floating near the surface.
- Some baleen whales use a feeding strategy known as bubble netting in addition to the more common filter feeding approach.
- The method known as bubble netting involves many whales surrounding a school of prey fish and blowing bubbles around them in order to herd the fish into a ball that can be brought to the surface.
Once the fish have been rounded up, the whales will take turns feasting on the defenseless prey they have captured. The humpback whale is recognized as being one of the whale species that feeds through the use of bubble nets. In a behavior that is often referred to as lunge netting, humpback whales will typically pursue prey such as herring while blowing bubbles to crowd the prey into a group.
- The fish will be frightened by the loud noises made by the other participating whales, which will cause them to swim closer to the surface.
- After breaking the surface, the humpback whales would charge the school of fish with their jaws wide open in an effort to consume as many fish as possible.
- When it comes to the process of searching for prey, baleen whales will, for the most part, engage in activities that are solitary.
On the other hand, certain species or pods of baleen whales will cooperate with one another in order to discover and secure food sources.
Does a blue whale eat meat?
Diets of blue whales Blue whales are the biggest animals that have ever existed, and their diets reflect this fact. These enormous cetaceans may grow to be 30 meters long and weigh up to 180 tons, which means that they require a substantial diet in order to maintain their ability to swim.
- But in spite of their gigantic size, blue whales get practically all of their nutrition from krill, which are shrimp-like crustaceans that only reach a maximum size of around six centimeters.
- These little creatures may be observed swimming in large swarms across the waters of the planet, which can number more than 30,000 individuals at a time.
The blue whale has one of the most voracious appetites of any known mammal, and it may consume up to four tons of krill in a single day. When feeding, blue whales, which have baleen plates, take enormous mouthfuls of water and food at the same time. They use the plates of their baleen to act as a sieve and then force the water back out of their mouths while keeping the food in their lips.
The right whale, the minke whale, the fin whale, and the sei whale all have baleen plates. All of them consume krill, but in addition to that, their diets may also contain other marine organisms, such as copepods, crabs, and fish of a smaller size. Herring and anchovies are two examples of schooling fish that can be aggressively hunted for by humpback whales and Bryde’s whales respectively.

Can blue whales swallow a human?
The blue whale’s neck is just too tiny to allow it to consume human flesh, which is the second reason why these whales are unable to consume human beings. The throat of a blue whale is less than one foot wide, which means that even if the whale wanted to try to swallow a person, it would be impossible for it to do so and it would not be able to. Phew!
Can blue whale swallow a car?
Science Message Delivered on January 3, 2017 – What is the largest object that a blue whale is able to consume? You had better consider that it is capable of consuming even tiny ships, automobiles, and even humans! In all candor, though, a blue whale’s neck is only around the size of a small salad plate, which means that the largest thing it can actually consume is a grapefruit.
How do whales filter food?
Each baleen plate has a hair of the baleen connected to it.

- Inside the mouths of baleen whales is a specialized filter-feeding system known as baleen.
- When a whale wants to use its baleen, it must first open its mouth underwater in order to drink water.
- The water is subsequently forced out of the whale’s body, and while it does so, creatures like krill are sifted through the baleen and preserved as a source of food for the whale.
The structure of the baleen is comparable to that of bristles, and it is made up of keratin, the same protein that is present in human fingernails, skin, and hair. Baleen is a skin derivative. Some whales, like the bowhead whale, have baleen that is far longer than that of other whales.
Some whales, like the gray whale, only use one side of their baleen, whereas others use both sides. The whale’s upper jaw has plates of baleen bristles organized in a pattern similar to that of a comb. A baleen plate’s length and weight can range anywhere from 0.5 to 3.5 meters (1.6 to 11.5 feet) and up to 90 kilograms (kg), depending on the species (200 lb).
Baleen hair, often known as whalebone hair, is the name given to its hairy edges. They are also referred to as baleen bristles, and in sei whales, the baleen bristles are strongly calcified. This calcification serves to improve the bristles’ rigidity. At the gumline, the plates of the baleen are wider (base).
