Largest and heaviest mammal of the world is
a. Elephant
b. Tiger
c. Lion
d. Blue whale

Answer 1

Hint: The higher vertebrates who are warm-blooded are called mammals like placentals, marsupials, or monotremes. The mammals consist of mammary glands that have a property to produce milk, give birth to young ones, and also they have hairs in their body. For example – human beings, dogs, cats, cows, monkeys, etc.

Complete answer:
> Option D:
The largest and heaviest mammal is the blue whale of the world that lived on Earth. The length of the blue whale is 100 feet and weight is 200 tons. The only tongue of the blue whale weighs as much as an elephant. The body of the blue whale is long and slender. It is a marine mammal. The lifespan of a blue whale is approx. 73 years. The blue whales are at the point of extinction.

> Option A:
The largest existing land mammal or animal on Earth is elephants. The legs of the elephant carry his weight which looks like a pillar. They have a long nose, or trunk, floppy ears, and thick legs. The smartest creature is the Elephant who has the largest brain out of all animals. The weight of the animal is approx. 2-7 tons.

> Option B:
The largest extant species of cat is Tiger which comes from the genus Panthera. These are vertical stripes of orange-brown fur. Tigers are an endangered species and disappearing soon. The weight of the tiger is approx. 280-300 pounds.

> Option C:
The species from the family Panthera which has a muscular deep-chested body is Lion. It consists of a short rounded head and ears with a hairy tuft at the end of its tail. The weight of the lion is approx. 400-420 pounds.

Hence, the correct answer is option (D).

Note: So we noted that the largest mammal in the world is the blue whale. It is a marine or aquatic mammal. It comes out of the water for completing the respiration process in his body. The blue whale is dying day by day that is why their population comes to an endpoint of extinction. There are less than 5 species of blue whale left. We should protect them and don’t let them become extinct.
