There are many amazing facts about blue whales, as they surely are some incredible animals. Blue whales are the largest existing animals, their dimensions being quite shocking. Blue whales also are very rare and this is the main reason why there are so few facts known today about these animals. Anyway, here are some very interesting facts about blue whales that you should definitely know.

Blue whales can grow up to 100 feet (30 m). The weigh of blue whales can reach 200 tones, and to really understand the huge dimensions of a blue whale, you should know that the heart of the animal weigh about 2000 pounds (907 kg). Having under consideration the impressive dimensions of the blue whale, the animal will eat about 4 tones of food a day. The heart of blue whales is actually considered to be weigh just as much as a car, while only its tongue is as long as an elephant. Blue whales are some of the most interesting creatures that exist today. The average weigh and the quantity of food they eat a day, are just two of the elements that shock when it comes to blue whales.

Measuring a blue whale is not something easy, as the whole process supposes cutting the animal into pieces. Specialists which study blue whales have actually been able to share facts about the animals only after performing this procedure, and there is no shock in that, as blue whales are considered to be larger than dinosaurs. Still, despite their huge dimensions, blue whales are capable of moving very quickly. Blue whales can actually cover five miles an hour, but they can also move much quicker when needed, being able to cover up to twenty miles in a single hour. Blue whales have an average lifespan of 60 to 70 years, although they can also live up to 110 years. Blue whales usually sleep in the middle of the day. Female blue whales stay pregnant for about twelve months and give birth to one calf at every two or three years. Anyway, the unfortunate reality is that blue whales are endangered species and it has been estimated that there only are 1300 to 2000 blue whales left.

Since 1964, when the Scottish physician and antiquary Sir Robert Sibbald described the blue whales for the first time, people have grown a significant interest in these creatures, because they are unique, one-of-a-kind and fascinating animals. Researchers have tried to find out as many things as they could about blue whales, so many documentaries and books were made about them. Blue whales rule the oceans all over the world and they are truly unique. They are nothing like anything we have ever seen before, precisely because they have unique features, that differences them from other animals, and which have set records.

Blue whales are so special because they are among the few mammal species who live exclusively in the water. They are also called aquatic mammals, because they give birth to baby blue whales, but their natural environment is aquatic. Then, another record set by blue whales is regarding their size. Blue whales are the largest animals that have ever lived on Earth. With a maximum length of 100 feet and an average weight of 120 tones, blue whales are even bigger than any dinosaur that has ever lived on this planet. Another impressive thing about the unique blue whales is the fact that they are not only the larger animals on Earth, but also the loudest ones. Their call reaches levels of up to 188 decibels and they can be heard for hundreds of miles. Blue whales are even louder than jets!

Other records held by blue whales involve the gestation period and the life expectancy. Blue whales have a gestation period of 11-12 months, which is longer even than the human pregnancy time. Then, blue whales can live up to 40 years, which is amazing considering the life expectancy of other animals. Unfortunately, the blue whales population has decreased dramatically, because they are heavily haunted. Today, it is estimated that about 10.000 to 14.000 blue whales are still alive, and they mostly live on the west coast of North America. As you can see, there are many fascinating things about blue whales, which make them some of the most unique creatures in the world.
