If you want to know the record holder for the largest animal in the world, then you're in the right place. The blue whale is considered the largest animal in the world. At 30 meters (98 ft) in length and 180 metric tons (200 short tons) or more in weight. Long and slender, the blue whale's body can be various shades of bluish-grey dorsally and somewhat lighter underneath. As with other baleen whales, its diet consists almost exclusively of small crustaceans known as krill. Blue whales can dive for up to an hour, going to a depth of 350 feet (105 m) and have a life expectancy of 35-40 years.
Note that the biggest land animal in the world is the African Elephant. African elephants males stand 3.2–4.0 m (10–13 ft) tall at the shoulder and weigh 4,700–6,048 kg (10,000–13,330 lb), while females stand 2.2–2.6 m (7.2–8.5 ft) tall and weigh 2,160–3,232 kg (4,800–7,130 lb). The African Elephant is larger than the Asian Elephant. These mammals have very strong social bonds and live in family groups headed by a female (called a cow). Males (called bulls) occasionally join the group. Elephants are excellent swimmers. Elephants have few natural enemies except man, and they are in danger of extinction due to loss of habitat and poaching (they are killed for their ivory tusks).
