The record-holder blue whale was recorded at 173 tonnes (190 short tons), [55] with estimates of up to 199 tonnes (220 short tons). [56] In 2024, Motani and Pyenson calculated the body mass of blue whales at different lengths, compiling records of their sizes from previous academic literatures and using regression analyses and volumetric analyses.
A large male ostrich can reach a height of 2.8 m (9.2 ft) and weigh over 156 kg (344 lb). [172] A mass of 200 kg (440 lb) has been cited for the common ostrich but no wild ostriches of this weight have been verified. [173] Eggs laid by the ostrich can weigh 1.4 kg (3.1 lb) and are the largest eggs in the world today. [citation needed]
However, the Alaskan hare (Lepus othus) has almost the same exact body-proportions and weighs slightly more, averaging 4.8 kg (11 lb) and reaching a maximum mass of 7.2 kg (16 lb). [70] Also, an occasional Arctic hare ( L. arcticus ) can also weigh as much as 7 kg (15 lb) but is typically smaller overall than the European and Alaskan species.

The largest animal currently alive is the blue whale. The maximum recorded weight was 190 tonnes (209 US tons) for a specimen measuring 27.6 metres (91 ft), whereas longer ones, up to 33 metres (108 ft), have been recorded but not weighed. [11] [12] [13] It is estimated that this individual could have a mass of 250 tonnes or more.

It measures 10–13 ft at the shoulder and consumes around 230 kg (500 lb) of vegetation a day. Its tusks have been known to reach 2.7 m (9 ft) in length, although in modern populations they are most commonly recorded at a length of 0.6–0.9 m (2 ft 0 in – 2 ft 11 in). [ 1 ]
