There are many different animals in the world. They are all very different from each other. Some live in the sea, others on land. Some feed on plants, others are predators. Some of them are small, others are huge and heavy.
The heaviest aquatic animal
The largest and heaviest aquatic animal in the whole world is rightfully the blue whale. Its length can be about 30 meters, and its weight starts from 180 tons and more. Such an animal has a dark blue color with bluish tints on the sides. The heart of a blue whale can weigh about 600 kilograms, and the tongue is about 2.5 tons, which can be compared in size to an elephant.
The volume of the lungs of a blue whale is more than three thousand liters in size, which is an absolute record among all known animals.
These whales feed on tiny organisms that live in the sea and are called krill. The blue whale can eat up to 40 million of these organisms per day. Most often, blue whales prefer to stay alone or in pairs. Such animals communicate using echolocation. The sound that blue whales utter when communicating is similar to the sound of a working jet plane and can be carried over vast distances, more than one thousand kilometers.
Blue whale females give birth to their cubs once every three years after a previous pregnancy that lasts about a year. The weight of a newborn kitten is around 3 tons.
The blue whale is a rather peaceful animal and has lost its belligerent abilities, which contributed to the almost complete extermination of this species.
The largest and heaviest land animal
The largest land animal is the African elephant. The animal is characterized by a heavy massive body, a short neck and a large head, as well as huge ears and thick limbs. The weight of a male African elephant can reach 6 tons, a length of about 7 meters and a height of just over 3 meters.
Females of the same animal weigh almost two times less. Their height is about 2.5 meters, and their length is about 5 meters. Adult elephants, due to their large size, most often do not have enemies in their natural habitat, but small elephants are quite often subjected to bloodthirsty attacks from crocodiles, lions, hyenas and leopards.
According to the latest statistical estimates, the population of these animals in the wild is about 550 thousand individuals. The largest animal killed is the African elephant, which was shot in Angola, weighing more than 12 tons, which is a record.
