[a] The polar bear is considered to be the largest extant species, [42] with adult males weighing 350–700 kg (770–1,540 lb) and measuring 2.4–3 m (7 ft 10 in – 9 ft 10 in) in total length. [43] The smallest species is the sun bear, which ranges 25–65 kg (55–143 lb) in weight and 100–140 cm (39–55 in) in length. [44]

The claws of a polar bear are quite different, being notably shorter but broader with a strong curve and sharper point. [27] [54] The species has large paws; the rear feet measure 21 to 36 cm (8.3 to 14.2 in) long, while the forefeet tend to measure 40% less. [55]

The Giraffidae are a family of ruminant artiodactyl mammals that share a recent common ancestor with deer and bovids.This family, once a diverse group spread throughout Eurasia and Africa, presently comprises only two extant genera, the giraffe (between one and eight, usually four, species of Giraffa, depending on taxonomic interpretation) and the okapi (the only known species of Okapia).
