At a weight of nearly 330,000 pounds, blue whales are indeed the biggest animal species to have ever walked the globe. Even newborn blue whales are enormous creatures, weighing close to 6,000 pounds. That's like giving birth to a rhinoceros adult-sized baby! Blue whales are gentle giants that inhabit almost all of the world's oceans, with the exception of the Arctic. 10 amazing blue whale facts can help you understand more about these wonderful animals.
1 - A row of plates inside the blue whale's mouth are bordered with "baleen," which resembles bristles.

The bristles are employed by the whale to filter food out of the water it swallows when feeding. For a blue whale, a mouthful of water contains roughly 5,000 kg of liquid and plankton. These bristles serve to catch and trap the food as the whale pushes water out of its mouth. The whale then uses its enormous tongue to lick the bristles clean, allowing it to consume the plankton.
2 - Every blue whale has a distinct marking of its own.
Prior to the advent of modern whaling in the late 19th century, little was understood about blue whales. But today's researchers have used photo-identification to discover that each whale's speckled pigmentation pattern is distinctive and a feature of the species. In sharp images, blue whales can be clearly identified by their distinctive mottling. In fact, the markings are so intricately detailed that perfect copies are incredibly unusual. Researchers have been able to learn more concerning the life spans and migration paths of blue whales because of this method of identification.
3 - The capacity of a blue whale's lungs is astounding.
Its expiration speed can reach about 372 miles per hour, and their lungs can carry about 5,000 liters of air (compared to humans' 6 liters) at 600 kph. The whales' capacity for storing oxygen in their red blood cells allows them to stay submerged for as long as an hour.
4 - The loudest creature in the world is the blue whale.
Blue whales have great hearing and use lower-frequency pulses, deep groans, whistling, rumbling noises, and groans to communicate with one another. At up to 188 dB, these whale calls are louder than just a jet engine. These noises are used by blue whales to communicate across great distances. About 500 kilometers away, their magnificent whale sounds have been captured on tape.
5 - Blue whales usually swim by themselves.
Blue whales can be found in all of the waters on our globe, excluding the Arctic. They typically swim by themselves or in bunches of 2–4. When there is enough available food, they may congregate in groups of up to fifty people.

6 - Blue whales aid in the battle against climate change.
Not only are blue whales crucial to the food chain of marine life, but they are also essential for preserving robust marine ecosystems and addressing the climate issue. The marine habitats are genuinely enriched by blue whales. In its lifetime, a single whale can often absorb the same quantity of carbon as 1,000 trees. Moreover, the excrement of blue whales fertilizes microscopic phytoplankton, which in turn produces approximately 50% of the oxygen on the planet and absorbs carbon. So, blue whales are essentially battling climate change. They are also crucial for the world!
7 - Milk from blue whales is fatty.
A blue whale's milk has a milk fat content of 35 to 50 percent, allowing the calf to gain weight. The calf consumes between 200 and 600 liters of milk per day to maintain dynamic growth. The expanding calf's average length will reach over 52 feet in just six months.
8 - For whale oil, the blue whale was once hunted.
The widespread hunting of blue whales during the 1900s had a negative effect on their population. For whale oil, which is extracted from their blubber, tens of thousands of them have been slaughtered. In the past, whale oil was commonly used to manufacture soap, margarine, and oil lamps.
9 - Blue whales are toothless.
These animals possess baleen, a filter-feeding mechanism inside their mouths, in place of teeth. The whale lets a lot of water and krill into its mouth when it eats. The krill gets imprisoned inside as soon as it passes through more than 300 baleen plates.
10 - There are just two predators of blue whales.
10 - There are just two predators of blue whales.
Due to its enormous size, the blue whale has few predators besides people and the killer whale family of oceanic dolphins. Only killer whales have ever been known to attempt to kill a blue whale. But a blue whale is roughly five to six times larger than a killer whale.
