How much do the heaviest animals in the sea and on land weigh? (+ infographic)
The African bush elephant is at the top of this ranking with a weight of 23,000 pounds (10,400 kg). The weight of this animal is more than twice that of the Asian elephant and the African forest elephant, both of which weigh 4 tons. Rhinos occupy four of the top 10 spots, and the 900 kg bison is the last animal on the list.
The maximum weight recorded for the blue whale is 190 tons, which is more than 18 times the weight of the African bush elephant. All 10 marine animals in this ranking are different species of whales, while elephants and rhinos have the largest share in the list of land animals. Even the lightest whales in the ranking of marine animals weigh more than four times the heaviest land animal.
According to Rosiato, from African elephants to blue whales, the heaviest animals in the world reach amazing dimensions. But what is the size and weight of the largest land animals compared to the creatures that live in the oceans?
This infographic compares the maximum weights reported for marine and terrestrial fauna by the Animal Fact and World Atlas websites.
These figures represent approximate maximum weights reported, not typical weights of mature animals.
In the table below, 10 heavy land animals are introduced based on the statistics published by Fact Animal.

Land animals, despite their huge size, have to bear all their body weight against the force of gravity. Their body size also affects how they move in natural environments; Including the amazing distances that some land animals travel with the longest migration routes.
In the table below, 10 heavy marine animals are introduced based on the maximum weights reported by World Atlas.
Whale hunting North Pacific Ocean
The blue whale with a weight of 190 tons is at the top of this ranking. After that, the North Pacific hunting whale, the fin whale and the bowhead whale, each of which is reported to weigh 120 tons.
But why can whales be so much heavier than land animals? A large part of the answer has to do with buoyancy. Water supports a significant part of the animal's body weight, and for this reason, sea giants can reach dimensions that would be very difficult to support on land.
Larger bodies also retain heat in the water more effectively. However, Stanford University research shows that the energy required to maintain and continue the life of huge bodies is one of the factors that limit the final size of aquatic mammals.
Of course, these maximum weights should also be considered as estimated figures. Weighing a large whale is much more difficult than weighing a terrestrial animal, and some of these figures are based on exceptional specimens or indirect measurements.
How did whales get so huge?
Although they spend their entire lives in the ocean, whales are descended from mammals that once walked on land. Over millions of years, their ancestors adapted to life in the water, developing elongated, water-sliding bodies, powerful tails, and other features suited to the marine environment.
This evolutionary transition eventually led to the appearance of the blue whale; The heaviest animal known so far in the history of life on earth.
The difference between whales and today's land mammals is striking. While elephants still hold the title of heaviest land animal, the ocean provides the physical conditions necessary for whales to reach completely different dimensions.
