Average size of blue whales
- The average length of blue whales ranges between 80-100 feet.
- The record length for this species is believed to be 110 feet.
- The average weight of blue whales is approximately 200 tons, with the heaviest blue whale on record weighing 330 tons.
Interesting Facts About the Size of Blue Whales
Blue whales, the largest creatures on Earth, possess unique and fascinating physical attributes that distinguish them from other species.
- These majestic marine mammals have a heart so massive that its weight is equivalent to multiple human adults combined.
- Similarly, the weight of their enormous tongue can be likened to that of a small car.
- Apart from their size, blue whales also have the largest brains of any animal on Earth, weighing up to 15 pounds (7 kilograms).
- Their circulatory system is also impressive, as their heart can pump over 330 gallons (1,250 liters) of blood with each beat, and their arteries are large enough for a person to crawl through.
- One of the most notable features of blue whales is their massive mouth, which can engulf up to 90 tons (81 metric tons) of water along with small fish and krill.
- Despite their bulk, blue whales are remarkably agile swimmers, able to reach speeds of up to 30 miles (48 kilometers) per hour.
- In addition to their physical attributes, blue whales are known for their distinctive vocalizations, which are the loudest animal sounds on earth. These calls can be heard for hundreds of miles across the ocean, and it has been suggested that they serve as a means of communication between the whales over long distances.
- Blue whales consume up to 4 tons (3.6 metric tons) of food per day, mainly consisting of tiny krill.
- Blue whale calves are born at a size of up to 25 feet (7.6 meters) and can gain up to 200 pounds (91 kilograms) per day during their first year of life.
- Finally, blue whales are among the longest-living mammals, with a lifespan of up to 100 years or more.
Preserving these magnificent creatures and studying their unique characteristics is crucial for future generations to appreciate and admire.

When comparing the animals, it’s important to note that their sizes and weights can vary significantly based on a number of factors. This table provides a rough comparison of the height and weight of some of the largest animals. It’s worth noting that animals like African Elephants and Brown Bears can have a range of sizes and weights within their species.
Comparison to other whales
- When it comes to whales, Blue Whales are considerably larger than Sperm Whales, measuring up to around 100 feet in length and weighing approximately 200 tons.
- Humpback Whales are also smaller, with an average length of around 50-60 feet and weight of around 40 tons.
- Orcas and Minke Whales are much smaller still, with lengths of around 20-30 feet and weights of around 5-10 tons.
Comparison to other large animals
- Compared to land animals, Blue Whales are truly massive.
- While Elephants are the largest land animals, they still pale in comparison to Blue Whales, with an average length of around 10-13 feet and weight of around 5-14 tons.
- Giraffes, the tallest land animals, are also considerably smaller than Blue Whales, with an average length of around 14-18 feet and weight of around 1-1.9 tons.
- Blue whales are one of the largest creatures to have ever existed on Earth.
- While the Argentinosaurus and the Blue Whale are thought to have weighed approximately 90 tons and 200 tons respectively, the sheer size of blue whales is still awe-inspiring.
- Accounts of blue whales measuring around 80-90 feet in length date back to the early 20th century, highlighting their impressive size throughout history.
Blue whale populations around the world display geographical variation in size, with some groups being smaller or larger than others.
A variety of factors can explain these differences, such as variances in food availability and genetic factors.
Food availability and genetics are both factors that influence the size of blue whale populations. For instance, colder waters with a higher abundance of food are linked to larger blue whale populations. In contrast, warmer waters with less food are associated with smaller blue whale populations.
Changes throughout life cycle
Throughout their lifetime, blue whales continue to grow, with lengths and weights increasing. However, as they age, blue whales eventually reach a maximum size before they start to shrink. This phenomenon can be attributed to food availability, genetics, and other environmental factors.
Overall, blue whales are fascinating creatures that are difficult to fathom in their enormity. By comparing their size to other whales, large animals, and historical context, we gain a better understanding of their place in the natural world. Visual aids such as images and graphs are essential for appreciating their size, and it is vital to continue studying and protecting them for future generations to enjoy.
