What is the biggest animal in the world? If you want to know what is the largest animal alive today or the largest animal who ever lived on earth, you need to know that the animal in question is one and the same, because, the largest animal nowadays is also the largest animal to have ever existed, namely the blue whale.

The Blue Whale (Balaenoptera musculus)

The blue whale is the largest marine mammal and the heaviest known animal to have ever existed, much larger than the largest dinosaur. The blue whale average mass is 110 tonnes (242,500 pounds) and the average total length is 24 meters (78 feet), even so, is 2-3 times larger than the heaviest Sauropod (Dinosaur) known from a complete skeleton. The heaviest blue whale was a female caught in the Southern Ocean on 20 March 1947, the whale had a recorded weight of 190 tonnes (418,878 pounds) and 27 meters (90 feet) in length. Generally, blue whale females are larger than blue whale males. The longest blue whale recorded was 33.58 meters (110 feet) in length, this is the record length for a mammal, but not for all the animals found on Earth, because, the longest animal found on earth is the bootlace worm, a record-breaking bootlace worm specimen was found to measure over 55 meters (180 feet) long. A blue whale has literally the biggest heart found on Earth, the blue whale heart can weigh around 680 kilograms (1,500 pounds) and is almost as large as a small car. Blue whales make the loudest sounds in the animal kingdom (almost 190 decibels), this low-frequency sounds (between 10 and 40 Hz) last less than thirty seconds and can be heard from hundreds of kilometers away. This magnificent and record-breaking animal species feed almost exclusively on krill, and because, blue whales have no teeth and use baleen plates for filtering food from water, they belong to the suborder of baleen whales, also called Mysticeti. Blue whales look truly blue underwater, but in reality the skin is blue-gray colored. Blue whales have a long streamlined body with a U-shaped flat head, long and thin flippers and small tail flukes.

A blue whale calf at birth is already among the planet's largest creatures with an estimated weight of 2-3 tonnes (4,400-6,600 pounds) and 7 meters (23 feet) long. A calf gains between 90 kilograms (200 pounds) and 110 kilograms (240 pounds) every day for its first year, the first six months calves drink only the mother's milk. Nowadays, with over 8000 blue whales swimming the world's oceans, they are declared an endangered species, the largest concentration of blue whales in the world feed along the California coast. Even though the global blue whale population is increasing the best chance to see a blue whale up close is to book a whale-watching cruise in the Gulf of Maine or in other areas of the world where blue whales have been frequently seen. Between March and September every year, more whales have been observed close to shore, in Southern California.
