How Much Does a Blue Whale Tongue Weigh?


The blue whale, or Balaenoptera musculus, is the largest animal on Earth and has fascinated scientists and nature enthusiasts for centuries. One of the most intriguing aspects of this magnificent creature is its massive tongue. In this article, we will delve into the world of blue whale tongues, exploring their size, weight, and other interesting facts.

The Size of a Blue Whale Tongue

The blue whale tongue is an astonishing anatomical feature that sets it apart from all other creatures. It is estimated that the tongue of an adult blue whale can reach a length of up to 30 feet (9 meters). This incredible length is necessary for the blue whale to consume its primary diet of krill, a small shrimp-like creature found in large numbers in the ocean.

The Weight of a Blue Whale Tongue

Now, let’s get to the heart of the matter – how much does a blue whale tongue weigh? The weight of a blue whale tongue varies depending on its size and age. On average, an adult blue whale tongue can weigh around 2.7 metric tons (2,700 kilograms or 5,952 pounds). To put this into perspective, this is roughly the weight of two small cars!

Factors Influencing the Weight

Several factors contribute to the weight of a blue whale tongue. These include:

  • Length: As mentioned earlier, the length of a blue whale tongue can range up to 30 feet, which adds to its overall weight.
  • Thickness: The tongue of a blue whale is not only long but also quite thick. The thickness adds to its mass and weight.
  • Tissue Density: The density of the tongue tissue also plays a role in determining its weight. The tongue is composed of a combination of muscles, connective tissues, and blood vessels.
  • Water Content: The water content within the tongue also contributes to its weight. The tongue is kept moist to aid in the swallowing of food.
Comparison with Other Animal Tongues

When comparing the weight of a blue whale tongue to other animal tongues, it becomes evident just how impressive it truly is. For instance, the tongue of an adult elephant, one of the largest land animals, weighs around 12-14 pounds (5.4-6.3 kilograms). In contrast, the blue whale’s tongue weighs thousands of times more!

FAQs (Frequently Asked Questions)

Q1: How does the weight of a blue whale tongue compare to its body weight?

A1: The weight of a blue whale tongue is relatively small compared to its entire body weight. An adult blue whale can weigh around 170 metric tons (170,000 kilograms or 374,785 pounds), making the tongue less than 2% of its total weight.

Q2: How is the tongue of a blue whale used for feeding?

A2: The massive tongue of a blue whale is crucial for its feeding process. When a blue whale opens its mouth, water rushes in along with the tiny krill. The whale then pushes the water out through baleen plates, which act like a filter, trapping the krill inside its mouth. The tongue pushes against the baleen, squeezing the water out and allowing the whale to swallow the krill.

Q3: Are blue whale tongues ever weighed in captivity?

A3: Due to the immense size of blue whales and the challenges of captivity, it is extremely rare to have the opportunity to weigh a blue whale tongue directly. Most information about their weight comes from estimates based on other factors, such as the weight of the entire whale or measuring tissue samples.

Q4: How does the size and weight of a blue whale tongue impact its movement?

A4: The large size and weight of a blue whale tongue do not hinder its movement. The tongue is incredibly flexible and muscular, allowing the whale to manipulate it easily. The whale’s tongue movements are vital for capturing and consuming vast amounts of krill efficiently.

Q5: Can a blue whale’s tongue grow even larger as it ages?

A5: The size of a blue whale’s tongue is primarily determined by its genetics and overall body size. While the tongue may grow slightly as the whale ages, its growth is generally proportional to the rest of the body’s growth. Therefore, it is unlikely for the tongue to undergo significant changes in size throughout its lifetime.

Q6: Are there any conservation concerns related to blue whale tongues?

A6: Blue whale populations have faced significant threats due to commercial whaling in the past. However, there are no specific conservation concerns directly related to their tongues. Conservation efforts focus on protecting the entire species and their habitats to ensure the survival and well-being of these magnificent creatures.


The weight of a blue whale tongue is an awe-inspiring characteristic of this magnificent creature. We have explored the size, weight, and various factors that contribute to the remarkable weight of a blue whale tongue. From its length and thickness to the density and water content, each element plays a role in making it one of the most extraordinary anatomical features in the animal kingdom. The tongue’s weight, though relatively small compared to its total body weight, is essential for the blue whale’s feeding process. As we continue to learn more about these gentle giants, let us appreciate the wonders of nature and strive to protect their fragile existence.
