Largest and heaviest animals

Rare card · No. 21797

The largest extant animal, as well as the largest animal to ever exist, is the blue whale. The maximum recorded weight was 190 tonnes for a specimen measuring 27.6 metres (91 ft), whereas longer ones, up to 33.6 metres (110 ft), have been recorded but not weighed. It is estimated that this individual could have a mass of 250 tonnes or more. The longest non-colonial animal is the lion's mane jellyfish (120 ft, 36.6 m). While controversial, estimates for the weight of the sauropod Bruhathkayosaurus suggest it was around 110–170 tons, with the highest estimate being 240 tons, if scaled with Patagotitan, although actual fossil remains no longer exist, and that estimation is based on described dimensions in 1987. Similarly, the extinct whale Perucetus was initially estimated in 2023 to have a mass of 85 to 340 t (94–375 short tons; 84–335 long tons). However, more recent studies suggest this whale was much smaller than previous estimates, with a 2024 study putting its weight at 60 to 113 tonnes...
