The largest extant monotreme (egg-bearing mammal) is the western long-beaked echidna (Zaglossus bruijni) weighing up to 16.5 kg (36 lb) and measuring 1 m (3.3 ft) long. [89] The largest monotreme ever was the extinct echidna species Murrayglossus hacketti , known only from a few bones found in Western Australia .
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]
Paraceratherium is one of the largest known land mammals that have ever existed, but its precise size is unclear because of the lack of complete specimens. [4] Its total body length was estimated as 8.7 m (28.5 ft) from front to back by Granger and Gregory in 1936, and 7.4 m (24.3 ft) by the palaeontologist Vera Gromova in 1959, [ 33 ] but the ...
