Difference between artiodactyls and equids.

Artiodactyls and equids are two orders of the Mammal class. Due to the similar sound and relative similarity of both groups of animals, identifying the differences between them presents a certain difficulty for schoolchildren.

Definition

Artiodactyls - this is one of the orders of Mammals.

Equid-hoofed animals are one of the orders of Mammals.

Comparison

Artiodactyls are a group of mammals. It includes 3 suborders:

  • ruminants - deer, giraffes, bulls, pronghorns, sheep, bison and antelopes;
  • calluses - camels;
  • Non-ruminants - hippos, pigs and bakers.

Artiodactyls are animals, the developed endings of the third and fourth classes of which are covered with a special case - a hoof. Moreover, their first toe is reduced, and the second and fifth are underdeveloped.

Artiodactyls are large and medium-sized animals. They have a characteristic elongated muzzle, and ruminants are also an obligatory decoration in the form of horns.

Artiodactyls are common on all continents except Antarctica. Initially, they were not only in Australia, but man "corrected" this oversight of Nature. Most of them live in open spaces (savannah, desert, tundra, steppe). A smaller part of the detachment chose the forest for life.

Deer. Artiodactyl order

Artiodactyls are a group of mammals. Today only 3 families of the once numerous taxon have survived on Earth:

  • the Equidae family - horses, zebras and donkeys;
  • the Tapirov family;
  • Rhinoceros family.

Equid-hoofed animals are animals whose hoof “covers” an odd number of toes.

Equids were once common on all continents except Antarctica and Australia. But in the wild, representatives of certain families can be found only in Africa, South and Central America, in Southeast Asia.

Horse. Order of equids

In addition to the number of phalanges that form limbs, another characteristic difference between the two orders of these animals, which formed the basis of taxonomy, is the scheme of the digestive system. The fact is that in equids the main digestion of food occurs in the large intestine, and in artiodactyls - in the stomach. Therefore, in equids, the stomach is single-chambered, and in artiodactyls, it consists of four sections - a scar, a mesh, a book, and an abomasum.

Conclusions TheDifference.ru

  1. In artiodactyls, a pair of toes forms a hoof; in equids, the hoof “covers” an odd number of toes.
  2. Artiodactyls in the wild are more common than equids.
  3. Artiodactyls have a more complex digestive system and a multichamber stomach.
