Larger than the largest dinosaur. They inhabit the Antarctic Ocean, North Atlantic, North and South Pacific, and Indian Oceans.
They are members of the order Artiodactyla and the family Balaenopteridae (or ‘Rorquals’), the largest organization of baleen whales, including the humpback whale and fin whale.
Blue whales typically live between eighty and ninety years, with some reaching up to one hundred and ten years of age.
Blue Whale Facts
They have a carnivorous diet, but despite their size, these massive sea creatures prefer to devour some of the smaller marine life forms. Blue animals feed on plankton called krill, a small animal that resembles a shrimp. Because of the relative sizes of blue whales and krill, they can consume up to 40 million krill, or 8,000 kilograms (3,600 kg) of krill, per day.
Despite having a maximum length of almost 30 meters (100 feet), blue whales are extremely adept swimmers. They can travel up to 50 km/h (31 mph) at their top speed, with an average cruising speed of about 8 km/h (5 mph). They are also excellent divers, diving to depths of 500 meters (1,640 ft) in search of krill to eat.
Because the blue animal is the largest living animal in the world, it has few predators. However, attacks by sharks and killer whales can injure or kill Sea animals. More commonly, they succumb to injuries sustained in collisions with large maritime vessels. The global population of blue whales is unclear, but according to IUCN research, the species’ global population is estimated to be between 10,000 and 25,000 and is classified as endangered.
Interesting information about blue whales
On the inside of a blue whale’s mouth, you can see a row of plates covered with “baleen” or bristles.
While the whale feeds, the bristles filter the food from the water it swallows.
sea animals can swallow up to 5,000 kilograms of liquid and plankton in a single gulp. The whale’s hairs catch and trap the food as the water is expelled from its mouth. The whale then uses its long tongue to lick the hairs, making it possible to swallow the plankton.
The tongue of a blue whale is the size of an elephant. The blue whale’s tongue weighs as much as an elephant or a passenger car but is used to catch krill on plates.
In the past, blue whales were hunted for their whale oil.
The extensive pursuit of blue whales during the 20th century harmed the numbers of this species. Hundreds of blue animals were killed for their oil, which is obtained from their fat. Whale oil used to be used to make soap, margarine, and oil lamps.
Before they were rescued in 1966, Sea animals were nearly wiped out through hunting.
It is believed that approximately 380,000 whales were stuck because of the upward thrust in the call for whale oil.
The Worldwide Whaling Commission acknowledges the sea animal as a protected species, allowing for a hit breeding.
The variety of blue whales is slowly growing. However, their population has not reached pre-crisis levels. Before the hunt, there were an estimated 240,000 blue whales worldwide. The current population is estimated to represent between 3 and 11% of the pre-1911 population.
A Sea animal weighs up to 200 tons. Or 150 Honda Civics.
They are the heaviest animals known to have ever lived on the planet.
Blue whales make few friends in the water.
Although it is common for them to swim throughout the world’s oceans alone or in pairs, the blue whale sometimes swims in a small group. Where food is readily available, up to 60 blue whales may gather.
The Sea animals are not only the largest in the world but also the loudest. The human ear cannot distinguish them underwater, but the Sea animals produce the loudest noise of any animal, up to 188 decibels – louder than a jet engine. The Sea animals speak with moans, groans, and low-frequency pulses.
The blue whale has exquisite hearing.
Because the Sea animals communicate with sounds of such low frequency, under the right conditions, they can speak to others and be heard at a high frequency.
