This is a list of maximum recorded animal lifespans in captivity. Only animals from the classes of the Chordata phylum are included. [1] On average, captive animals (especially mammals) live longer than wild animals.
The 100 species with longest life-spans recorded and verified [1] This is a list of the longest-living biological organisms: the individual(s) (or in some instances, clones) of a species with the longest natural maximum life spans. For a given species, such a designation may include:
A mutation in the age−1 gene of the nematode worm Caenorhabditis elegans increased mean life span 65% and maximum life span 110%. [82] However, the degree of lifespan extension in relative terms by both the age-1 and daf-2 mutations is strongly dependent on ambient temperature, with ≈10% extension at 16 °C and 65% extension at 27 °C.
A study published in Biology Letters estimated that they have a maximum lifespan of over 100 years and that the lifespan of an average adult is around 68.5 years. When compared to the longevity and body mass of other amphibians, olms are outliers , living longer than would be predicted from their size.
Mammals range in size from the 30–40 millimetres (1.2–1.6 in) bumblebee bat to the 30 metres (98 ft) blue whale—possibly the largest animal to have ever lived. Maximum lifespan varies from two years for the shrew to 211 years for the bowhead whale.
The West African giraffe (G. c. peralta) is endemic to southwestern Niger. [1] This animal has a lighter pelage (fur) than other subspecies, [33]: 322 with red lobe-shaped blotches that reach under the hocks. The ossicones are more erect than in other subspecies, and males have well-developed median lumps.

More than a thousand wild reticulated pythons in southern Sumatra were studied, and estimated to have a length range of 1.5 to 6.5 m (4 ft 11 in to 21 ft 4 in), and a weight range of 1 to 75 kg (2 lb 3 oz to 165 lb 6 oz). [27]
