Top 10 Amazing Facts
- The blue whale is the largest animal to ever live on Earth. It reaches 33 meters in length and can exceed 150 tons in weight.
- The blue whale has the largest heart ever — the adult heart weighs about one ton. Their heart rates range from 5 to 10 bpm with a maximum of 37 bpm.
- Whales do not spout water — they just exhale air when coming up to the surface. This air is saturated with water vapor, and when meeting the outside cooler temperature, it forms a column that looks like a fountain.
- The blue whale's tongue alone weighs up to four tons. For you to compare: this is the weight of an Asian elephant.
- Normally, the
blue whale spends 94% of its time underwater and dives to a depth of 100–200 meters.
In case of danger, the blue whale is able to dive up to 500 meters deep!
- Whales are free from caisson disease. Unlike scuba divers, whales do not need to breathe underwater. Whales conserve the fixed oxygen mainly in the blood and muscles. When diving, the pressure compresses their lungs and squeezes the air into the upper respiratory passages, thus almost stopping the gas exchange.
- Blue whales use low-frequency sounds to communicate with each other at a distance of up to 1600 km!
- The blue whale has a very huge lower jaw. A mouth full of water and food sometimes may hinder jaw movements due to the heavy load. Then the whale turns over on its back, and the mouth gets shut under gravity.
- Having such a huge size, the blue whale needs to eat lots and lots of food. The blue whale consumes up to 4 tons of krill a day.
- Water pollution puts blue whales at risk. Studies have shown that toxic chemicals accumulate in the blue whale's fat tissue. Moreover, pregnant female whales transfer these toxic substances to their calves in the womb.
