Are blue whales endangered ?

#1 : What is the blue whale size ?

When it comes to sheer size, the blue whale reigns supreme among all living creatures. Adults can reach astonishing lengths of up to 100 feet (30 meters) or even more, with the largest individuals surpassing even this remarkable measurement. To put this into perspective, a blue whale is longer than the average school bus and even more than most massive dinosaurs in terms of sheer length. Here is a comparison of this beast with a human to give you a clear idea !


In addition to their impressive length, blue whales can weigh an astounding 200 tons or more. Imagine a creature heavier than 33 elephants or roughly the weight of 33 small cars. Their skin color varies from a mottled blue-gray to a deep blue, with patterns unique to each individual. The life longevity of these gentle giants is equally fascinating, with some individuals believed to live for more than 90 years.

#2 : Where do blue whales live ?

Blue whales are well-traveled beings, traversing various oceans across the globe. Their preferred habitats include the North Atlantic, North Pacific, Indian Ocean, and the Southern Ocean. These vast expanses provide the resources necessary for the blue whales' survival, particularly the rich feeding grounds where they find their primary food source.


Despite their widespread distribution, blue whales are known for their migratory behavior. They often embark on journeys covering thousands of miles, seeking optimal conditions for feeding and reproduction. During the summer months, blue whales tend to move towards cooler, nutrient-rich waters to capitalize on seasonal abundance.

#3 : What does blue whale eat ?

While their size is undoubtedly remarkable, their eating habits are equally fascinating. Despite their immense bulk, these marine mammals are filter feeders, relying on a diet almost exclusively composed of small marine organisms known as krill. These tiny shrimp-like creatures are abundant in the oceans and serve as the primary source of nutrition for blue whales.

Blue whales use baleen plates to filter krill from the water. They take massive mouthfuls of water, then close their mouths and use their massive tongues to push the water out while trapping krill against the baleen plates. This process allows the whales to consume large quantities of krill in a single gulp.


To sustain their massive bodies, blue whales need to consume an astonishing amount of krill every day. Estimates suggest that an adult blue whale can consume around 4 tons of krill per day during peak feeding season. This is just impressive! But can this cause disturb their environment...

#4 : Are blue whales endangered ?

Despite their magnificence, blue whales are not exempt from the threats that plague many marine species today. Historically, they faced the harrowing danger of commercial whaling, which decimated their populations. Although there are international bans on whaling, these gentle giants still face challenges such as ship strikes and entanglement in fishing gear. Additionally, the changing climate and its impact on ocean ecosystems could disrupt the availability of their primary food source, krill, potentially leading to a decline in their numbers.
