[2] [3] [4] Animals have been selected so that each number from 0 to 55 leg pairs has one example listed. Each of these examples is listed by a number closely associated with the relevant taxon, either because that number is the one most commonly observed in that taxon or because it is one of only a few numbers recorded for the taxon.
Because of this, camelids have to lie down by resting on their knees with their legs tucked underneath their bodies. [1] They have three-chambered stomachs , rather than four-chambered ones; their upper lips are split in two, with each part separately mobile; and, uniquely among mammals, their red blood cells are elliptical.

Hippopotami and camels are ungulate mammals with a three-chambered stomach (ruminants have a four-chambered stomach) while equids (horses, asses, zebras) and rhinoceroses are monogastric herbivores.
