The Uniqueness of Blue Whales to the Animal Kingdom

Blue whales are the largest creatures on our planet - so massive, in fact, that a small child could swim through their largest veins and arteries.

An adult blue whale can measure up to 100 feet (30 meters) long, which is approximately the height of a 10-story building, and can weigh up to 200 tons.

Interestingly, despite their colossal size, their diet mainly consists of tiny aquatic creatures known as krill.

During the feeding season, a blue whale consumes about 4 tons of krill per day.

Despite their size, they are not dangerous to humans as they primarily eat small ocean creatures.

Blue whales are also the loudest animals on Earth.

They communicate using a series of low-frequency pulses, groans, and moans.

It is believed that in good conditions, blue whales' calls can be heard up to 1,000 miles (1,600 km) away.

Unfortunately, blue whales are currently listed as endangered species due to extensive hunting in the early 20th century..
