Diverse is not enough to describe the world we are living in. While every living creature, whether big or small or tall or short, plays an important role in balancing the ecosystem, you can’t help but feel lucky knowing that you have an advantage over the others. However, there are certain creatures that are big enough for man to handle, which gives a slim chance of surviving. So the next time you go underwater, watch out for blue whales, the biggest animal on Earth.

They measure up to 180 metric tons and can grow as much as 100 feet or 30 meters long. And watch out for their tongue because it can weigh as much as an elephant while their heart is as heavy as an ordinary vehicle.

A baby blue whale’s size is also notable. It can weigh up to 2.7 metric tons and can grow as long as 25 feet. Since it survives through its mother’s milk, baby blue whales can gain 91 kilograms everyday during its first year.

These magnificent creatures are called blue whales because they look blue underwater. But once they are on the surface, its color turns into blue gray. Its underbellies are also yellow in color because of the millions of microorganisms living on its skin.

Big and Small Blue Whale

These whales are known to be graceful swimmers and cruise the ocean at eight kilometers per hour. But once they are disturbed, they can go as much as 32 kilometers an hour. So be sure not to disrupt them.

Loudest and Longest-living Animals

Aside from being the biggest, they are also among the loudest mammals where they make series of pulses, groans and moans. It is also believed that thse animals can hear each other up to 1,600 kilometers in good conditions.

The Loudest Animal

Theyare also considered as the longest-lived animals. In fact, the oldest blue whale found was around 100 years old, according to the measurement of its wax-like earplugs which determines its age. Nonetheless, average lifespan of this creature is around 80 to 90 years.

Diet

Blue whale diet consists of feeding itself with krill, a shrimp-like animal, or at times, small amount of copepods. A single blue whale can eat about 4 tons of krill in just one day.

Blue whales are baleen whales that have fringed plates of fingernail-like material attached to their upper jaws. When feeding, they first gulp a mouthful of water which expands its pleated skin on their throat and belly. In effect, its tongue forces through the baleen plates where thousands of krill will be swallowed.
