The largest land mammal extant today is the African bush elephant. The largest extinct land mammal known was long considered to be Paraceratherium orgosensis, a rhinoceros relative thought to have stood up to 4.8 m (15.7 ft) tall, measured over 7.4 m (24.3 ft) long and may have weighed about 17 tonnes.
At 8 kilometres (5 mi) across, and estimated at 100,000 years old, [3] it may be one of the largest and oldest clonal colonies on Earth. [4] [5] [6] Among animals, the largest species are all marine mammals, specifically whales. The blue whale is believed to be the largest animal to have ever lived. [7]
“The size of these magnificent creatures was incredible," Fry said in a news release earlier this month. "One female anaconda we encountered measured an astounding 6.3 meters (20.8 feet) long."
The largest of the monitor lizards (and the largest extant lizard in genera) is the Komodo dragon (Varanus komodoensis), endemic to the island of its name, at a maximum size of 3.13 m (10.3 ft) long and 166 kg (366 lb), although this is currently the only record that places the mass above 100 kg (220 lb).

Scientists consider the blue whale, which grows up to 110 feet (33.5 meters) long, to be the largest known animal ever to exist on the planet. But it’s possible that the 202 million-year-old ...
The heaviest land mammal is the African bush elephant, which has a weight of up to 10.1 t (11.1 short tons).It measures 10–13 ft at the shoulder and consumes around 230 kg (500 lb) of vegetation a day.
Fragmentary fossils of extinct rorquals from the Pliocene epoch suggest they rivaled the size of the largest whales today. [39] Perucetus, the largest Archaeoceti, has an estimated length exceeding 17.0–20.1 meters and weight ranging from 85–340 t which also rivaled the size of the largest whales today. However, later studies proposed a ...
In zoology, megafauna (from Greek μέγας megas "large" and Neo-Latin fauna "animal life") are large animals. The most common thresholds to be a megafauna are weighing over 46 kilograms (100 lb) [ 2 ] [ 3 ] [ 4 ] (i.e., having a mass comparable to or larger than a human ) or weighing over a tonne , 1,000 kilograms (2,205 lb) [ 2 ] [ 5 ] [ 6 ...
