Do blue whales have predators?
Orcas take down a blue whale, proving they're the apex predators of the ocean. While killer whales are known to attack blue whales, John Totterdell and his colleagues are the first to ever document a successful takedown. And they've done it more than once, publishing their findings in the journal Marine Mammal Science.
How do whales protect the ocean?
They play a vital role in the health of the oceans where they help provide up to 50% of our oxygen, combat climate change and sustain fish stocks. 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.
Why do blue whales have no predators?
Because of their size, power and speed, adult blue whales have virtually no natural ocean predators. The only sea creature known to attack blue whales is the orca whale (scientific name: Orcinus orca) also known as the “killer whale”. They have been known to work in groups to attack blue whales.
What has helped protect blue whales?
Blue whales are protected under both the Endangered Species Act and the Marine Mammal Protection Act. NOAA Fisheries is working to protect this species in many ways.
Are blue whales friendly?
In a nutshell, yes, blue whales are friendly animals. These animals feed almost exclusively in krill, so have no interest in humans and are not a threat to us.
What are 5 facts about blue whales?
Consider the following.
- Blue Whales Can Grow More Than 100 Feet Long.
- They Can Weigh as Much as 30 Elephants.
- They Have Big Hearts.
- They Have Big Tongues, Too.
- They Have the Biggest Babies on Earth.
- They're Unusually Loud.

- They're Pretty Fast.
Can a blue whale defend itself?
Well, whales protect their young similarly to how they'd protect themselves – by traveling in pods. Again, by traveling in numbers, whales make it harder for sharks or orcas to target a specific member. If they feel threatened, though, whales will form a circle with their head facing inward, tail facing out.
How do whales save the planet?
Whale excrement fertilizes the ocean, producing large phytoplankton blooms that absorb enormous amounts of carbon dioxide. Scientists point out that helping whale populations recover from past overharvesting can help reduce greenhouse gas levels in the atmosphere.
How do blue whales escape predators?
However, the blue whale has one formidable weapon: its tail, which can be as wide as a soccer net. It can scare off or even injure a predator with a powerful flick of its tail.
How does a blue whale survive?
Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth …
Do whales fart?
The short answer is yes; whales do fart, flatus, or pass gas, depending on how you like to phrase it. In fact, whales, dolphins, and porpoises are all marine mammals belonging to the cetacean species, and they are all known to fart.
Do whales love humans?
From a historical perspective, whales do appear to be non-aggressive. Their relatives, the dolphin's species, tend to be very friendly and curious towards humans, often displaying a desire to greet and meet people.
Who would win killer whale or blue whale?
With all of this in mind, a blue whale would win in a one-on-one fight against an orca, though a pod of orcas could likely take down a single blue whale.
Are blue whales violent?
What is this? As a species, whales are generally non-violent and do not display aggressive behaviors towards humans; however, in situations where a whale may feel threatened or frightened, it may defend itself by attacking what it thinks is a potential threat.
How do whales help with oxygen?
The whale pump These microscopic creatures not only contribute at least 50 percent of all oxygen to our atmosphere, they do so by capturing about 37 billion metric tons of CO2, an estimated 40 percent of all CO2 produced.
How do whales prevent global warming?
Protecting whales can have climate benefits “Whales accumulate carbon in their bodies during their long lives. When they die, they sink to the bottom of the ocean, locking that carbon away for hundreds of years – a literal carbon sink. Each great whale sequesters 33 tons of CO2 on average.
What defense do whales have?
The primary defense mechanism of a whale is its tail. A humpback whale can scare or injure a predator with the tail. Like dolphins, whales can also use their head to scare away predators and other marine enemies.
What helps whales survive?
When present, the dorsal fin is helpful for stability and has no support in the way of bones. Whales are able to survive in deep or freezing polar water because of a layer of fat, called blubber , covering their entire body underneath the skin. Blubber is much thicker than the fat found in other mammals.
Do girls fart?
Yes, girls fart. Whether the passing of intestinal gas is odorless or smelly, silent or loud, in public or in private, everybody farts!
Do 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.
Do whales cry?
Whales, do however vocalize their emotions and may moan, whine or produce crying sounds or sad whale songs when they feel sad, alone or upset, which allows other whales and marine mammals to know how they feel and gives them the ability to express their emotions whether they are alone or around other whales.
Who is the king of the ocean?
Great white sharks, to be exact. But the true ruler of the sea is the killer whale. 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.
What are orcas afraid of?

Why are whales so friendly to humans?
From a historical perspective, whales do appear to be non-aggressive. Their relatives, the dolphin's species, tend to be very friendly and curious towards humans, often displaying a desire to greet and meet people.
How do blue whales breathe?
They breathe through nostrils, called a blowhole, located right on top of their heads. This allows them to take breaths by exposing just the top of their heads to the air while they are swimming or resting under the water.
How are whales saving the planet?
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. They also capture about 37 billion tonnes of carbon dioxide or four Amazon forests' worth.
How do blue whales survive?
Among these adaptations are: streamlined bodies for efficient movement through water; forelimbs modified into flippers to aid in steering; hind limbs internalized remnants reducing drag; tail positioned horizontally to achieve a powerful up and down propulsion; hair replaced with under-skin blubber to provide warmth …
How do blue whales survive the cold?
Whales are warm blooded marine mammals that can tolerate cold water temperatures. Whales use blubber as an insulation layer to help maintain the energy and warmth when they dive to cool depths or travel to cold waters such as in Alaska. The blubber layer is a thick (6 inches) layer of fat that is found under the skin.
How do blue whales survive in cold water?
Whales are warm-blooded mammals that can survive in water temperatures as frigid as the low 40s F. How do they manage to stay warm, even in the ice-cold waters of the Atlantic? By wearing a thick layer of fat, called blubber, just beneath the skin.
Can you taste a fart?
You won't be able to taste a fart that escapes through your mouth. Flatulence is made up of swallowed air and gas produced by bacteria in the colon from undigested carbohydrates. It smells bad due to the breakdown of various foods into certain gases, primarily sulfur-containing gases.
