Not only are blue whales () the largest animals in the sea, they are also the largest animals ever to live on this planet – even bigger than all known dinosaurs. Blue whales can grow to about 100 feet long, which is a little longer than a basketball court.

With all of that size, the blue whale needs a big heart. In fact, they have the biggest hearts on the planet. The heart of a blue whale weighs more than 1,000 pounds, the weight of an average dairy cow. A blue whale heart pumps about 60 gallons (7,680 ounces) of blood with each beat. In comparison, a human heart pumps merely 2.4 ounces with each beat.

The aorta of a blue whale heart is so big that a human being could crawl through it!
Text Below for Accessibility Between Valentine’s Day and American Heart Month, you probably have hearts on the mind this February. Check out these facts of the heart of the world’s largest creature, the Blue Whale.

A blue whale’s heart is the biggest on the planet, weighing 400 pounds. That’s the weight of about 35 gallon paint cans. A blue whale’s heart is only 1% of its body weight – however the whale’s immense weight is supported by water. Is a blue whale’s heart really the size of a small car? In 2015, a dissection team in Canada extracted and measured a blue whale’s heart from a whale that washed ashore. No, it wasn’t as big as a Volkswagon – more like a small golf cart. (Still big.)A blue whale’s heartbeat slows dramatically during dives to over 1,000 feet. In one study, a diving blue whale’s heart slowed to 4-8 beats a minute, with an extreme low of only two beats, a drastic measure to save oxygen. Amazingly, between those beats, the aortic artery contracted to keep blood moving. When the whale came to the surface to breathe, its heart raced to 25-37 beats a minute. Scientists think that that a whale’s heart works close to physical limits and cannot beat faster, which is why whales have reached their largest size possible.The aorta measures over 9 inches. That’s the size of a dinner plate. Bon Appetit!And the best fact of all: a blue whale’s heartbeat can be detected from 2 MILES AWAY.

How big is the heart of a whale?

How far away can you hear a blue whale’s heartbeat?

Heart Rate –

  • At a rate of 2 – 10 bpm when submerged, the blue whale’s heartbeat can be heard from over 2 miles away.
  • However, when not submerged a surfaced blue whale’s heart rates measure as high as 25 – 37 bpm.
  • Notably, the heart rate is considerably influenced based on whether the blue whale is underwater or floating at the surface.
  • Numerous heart rate recordings also exhibit changing heart rates depending on the particular whale, its size, and its condition.
  • The large heart and slow heart rate help blue whales manage blood/oxygen levels efficiently during long dives.
  • As a result, they’re able to hold their breath longer than other animals not adapted for aquatic life.
  • In comparison to a blue whale, a heart has a heart rate of 35 – 45 beats per minute, and a human’s heart has an average heart rate of around 60 – 100 beats per minute.
  • If you’ve ever seen a ten-story building, it will give you an idea of just how big the blue whale is overall.

Why are blue whales endangered and how to save them?

Download Article Download Article The blue whale helps provide a large amount of oxygen into the earth’s atmosphere. Unfortunately, ocean pollution, boat strikes, and the whaling industry are a constant threat to these endangered animals. To make the world a cleaner, safer, and healthier place for blue whales to take your support to the next level, consider donating money or providing legal support for helpful legislation.

  1. 1 Opt to go on a whale watching tour instead of a marine attraction. If you’d like to spend some time around blue whales, sign up for a whale watching tour, which allows you to see the mammals in their native environment. During the tour, ask the guide questions about the biggest threats to the whales in the area.
    • Many coastal cities like San Francisco, Maui, Boston, and Newport have whale watching tours. If you live near the ocean, check online to see what kinds of whale watching programs are operating near you.
  2. 2 Adopt a whale on a charity site to show your support. Search on the websites of large organizations for blue whale “adoption” opportunities. While you won’t be owning or caring for a physical whale, your gesture will directly serve conservation and protection efforts for blue whales. With some organizations, you can purchase different adoption “tiers,” which give you photos, informational cards, and other rewards for your support. Advertisement
  3. 3 Participate in beach clean-ups to reduce pollution in the ocean. If you live near the coastline, look online for local clean-up events happening in your area. When necessary, register online for the project so you can participate. If there are no beach clean-up projects happening, try organizing one yourself !
    • When you get rid of litter, you help make the ocean a safer and healthier place for Blue Whales.
    • Blue whale adoptions can also be done virtually, and given to friends and family members as gifts.
  4. 4 Give money to a whale sanctuary project. If you live in a coastal region, search online for information on any whale sanctuaries being constructed near you. Regardless of your location, use an online donation option to give money to the development and construction of future buildings. Since these projects cost millions of dollars to complete, any amount can help!
    • Sanctuaries provide blue whales with a safe place to live and reproduce without any threats from shipping and pollution.

  1. 1 Sign online petitions that advocate for the blue whales’ protection. Search on different advocacy sites for petitions related to the safety and wellbeing of blue whales. Additionally, check government-sponsored websites for petitions; depending on the website, the petition might be viewed by the government if it gets enough signatures.
    • For instance, a petition that only says “Save the whales!” wouldn’t be very helpful or productive in the long run. Instead, look for a petition that says something like: “We want to push for legislation that reduces pollution by”
  2. 2 Boycott large companies that participate in the whaling industry. Research if the grocery stores, distributors, and brands in your region work with any whaling companies. Even if the companies aren’t actively participating in whaling, make an effort to avoid their products and business until the company’s leadership makes a change in their policy.
    • Be on the lookout for companies that do business with known whaling affiliates, like HB Grandi.
    • On the other hand, look for businesses and brands that actively speak out against whaling, and direct your patronage there.
  3. 3 Contact a local representative in your government to make your opinion heard. Search on the national website of your government to find the contact information for both local and federal officials. When writing a letter for the first time, focus on a mayor, state legislator, or county executive.
    • For instance, try writing something like this: Dear Mr. Johnson, I am contacting you to remind you about an upcoming vote for pollution control. This legislation is extremely important to saving the blue whale species, which is currently endangered.
    • When addressing a letter to an official, be sure to use their full title in the return address (e.g., The Honorable Steve Grant).
  4. 4 Write a letter to a foreign ambassador of a country that supports whaling. Check on your nation’s website to find contact information for specific ambassadors and embassies. Using the email or address provided, draft a short, concise message to the official, stating your intention and disagreement with the whaling practice.
    • For example, try writing something like this: Dear Mr./Madam Ambassador, I am writing to you today to discuss your country’s participation in the whaling industry. With this in mind, I’d like to bring to your attention that hunting the blue whale, in addition to other marine mammals, is an issue of international concern.

    • When you get rid of litter, you help make the ocean a safer and healthier place for blue whales.
    • If you don’t live near the coast, you can still make the environment cleaner by participating in a local litter clean-up.
  2. 2 Recycle and toss out unwanted items properly to reduce ocean pollution. Check on your town or city’s website to see what their trash and recycling policies are. Specifically, memorize your neighborhood’s recycling and trash collection schedules, you can dispose of your waste in a timely and effective manner. If you have a lot of organic waste on hand, try composting it instead.
    • Don’t litter, or toss trash and recyclables into the environment. Although you might not think it’s a big deal, litter is a huge contributing factor to ocean pollution, which has a negative impact on blue whales.
    • Be especially careful when disposing of items like fishing lines, fish hooks, and plastic six-pac rings. If these items wash into the ocean, marine life can get tangled in them.
  3. 3 Throw out hazardous waste in a safe, careful way. Look on your town or city’s website to find the best way to throw out toxic materials, like batteries, chemicals, and old medication. Avoid pouring or dumping any toxic materials down the drain or in an open area, as these substances can pollute the surrounding waterways, including the ocean.
    • Don’t keep your toxic waste in food containers.
    • Although it might seem practical, don’t combine different types of waste into one bottle or container. This could cause the chemicals to ignite or cause a bad chemical reaction.
  4. 4 Check your vehicle for leaks to prevent unwanted runoff into the ocean. After driving your vehicle, check around and beneath the car or truck for any signs of leaking. If notice any oil dripping from your car, take the vehicle to an appropriate mechanic immediately.
    • After after a rainstorm, this oil run-off will flow into storm drains, which eventually lead to major water sources. When lots of unhealthy substances eventually drain into the ocean, it creates an unhealthy environment for whales.
    • Follow your city’s protocols whenever you dispose of used motor oil and other caustic materials.
    • Some places will recycle old car oil free of charge.
  5. 5 Avoid using excess pesticides and fertilizers to prevent toxic run-off in the ocean. While lawn and gardening additives can be helpful in a pinch, you don’t want to saturate your yard with them. Always follow the bag or bottle’s instructions when applying fertilizer and pesticides, so you don’t apply too much product to a single area.
    • After a rainfall, these substances wash away into storm drains, which lead into larger water sources. When lots of these chemicals wash into the ocean, it creates an unhealthy environment for blue whales.
    • Some farms use special, environmentally-friendly method known as integrated pest management (IPM) to get rid of bugs and pests carefully. Look for specifically suggestions here:,
  6. 6 Opt for reusable items to prevent excess pollution. Pay attention to how many plastic, paper, or other disposable items that you use on a weekly basis. Whether you’re eating out or shopping for your own household, opt for straws, cups, and plates that can be washed and reused again.
    • If you choose to use plastic bottles and bags, be sure to recycle them correctly.
  7. 7 Develop careful shopping habits that don’t generate extra waste in the ocean. If you feel tempted to make an unnecessary purchase, give yourself a week to ponder the decision. If you don’t need the product in your daily life, then you probably don’t need to purchase it. When you’re buying necessary items, like groceries and toiletries, use reusable shopping totes instead of plastic bags.
    • Try not to buy food items that are wrapped in plastic wrap. While a piece of wrap may seem small, it can contribute to a much larger pile of waste and ocean pollution once it’s thrown out.
    • Cigarette butts are a huge source of beach pollution.
