The main axes of both the front and rear feet pass through the third toe, which is always the largest. The remaining toes have been reduced in size to varying degrees. Tapirs, which are adapted to walking on soft ground, have four toes on their fore feet and three on their hind feet. Living rhinos have three toes on both the front and hind feet.
The order Artiodactyla consists of 349 extant species belonging to 132 genera. This does not include hybrid species or extinct prehistoric species. Modern molecular studies indicate that the 132 genera can be grouped into 23 families; these families are grouped into named suborders and many are further grouped into named clades, and some of these families are subdivided into named subfamilies.
Many artiodactyls are territorial and mark their territory, for example, with glandular secretions or urine. In addition to year-round sedentary species, there are animals that migrate seasonally. There are diurnal, crepuscular, and nocturnal artiodactyls. Some species' pattern of wakefulness varies with season or habitat.
The feet of the front limbs in chameleons, for instance, are organized into a medial bundle of digits 1, 2 and 3, and a lateral bundle of digits 4 and 5, while the feet of the hind limbs are organized into a medial bundle of digits 1 and 2, and a lateral bundle of digits 3, 4 and 5. [10]
The analysis of the additional toe numbers of Maine Coon cats revealed that the number of toes follows a developmental bias: 2 additional toes occur much more frequently than 4, these more frequently than 6 or 8 additional ones. [34]

Here, "|" (pipe symbol) marks the beginning of a foot in the line. Thus there are six feet, each of which is either a dactyl (– u u) or a spondee (– –). The first four feet can either be dactyls, spondees, or a mix. The fifth foot can also sometimes be a spondee, but this is rare, as it most often is a dactyl. The last foot is a spondee.
