Even-Toed Ungulates: Comprehensive Guide

An even-toed ungulate is a popular term for any of the hoofed animals, primarily herbivorous and terrestrial mammals that belong to the order Artiodactyla. They are distinguished by a bone in the ankle joint and an odd number of functional toes (2 or 4), with the main limb axis running between the middle two digits.

The even-toed ungulates, also known as cetartiodactyla (from the Latin “Cetus” meaning ‘whale,’ and “artus” meaning ‘limb’), is an order of even-toed hoofed mammals that includes pigs, hippopotamuses, camels, and deer. They differ from the odd-toed ungulates in that they have a single large toe on either side of their hooves. Their skin is thick to protect them from parasites and adverse weather conditions.

History of Even Toed Ungulates

They initially emerged in North America during the late Eocene, and through time, they diversified into a large number of different species. Their migration from North America into Eurasia took place only in the late Miocene or early Pliocene epochs. It is estimated that the North American variety went extinct around 10,000 years ago.

A list of artiodactyls includes well-known members such as pigs, peccaries, hippopotamuses (mouse deers), deer (mouse deer), giraffes, camels, pronghorns (antelope), goats, sheep, and cattle, among others. One of two extant orders of ungulates (hoofed mammals), the other being Perissodactyla, which includes the odd-toed ungulates, is the Artiodactyla.

How Many Species of Even-Toed Ungulates Exist?

Artiodactyls are the most abundant big terrestrial animals on the planet today, with more than 220 different species. They are also extremely important to humans in terms of nutrition, economics, and culture. Domestic species, in particular, are greatly sought after for various purposes, including food, fur, milk, fertilizer, medical goods, and draught animals. Additionally, wild animals like antelopes and deer give food and opportunitiesOpens in a new tab. for sporting shooting and contribute to the wonder of nature. Wild artiodactyls play critical roles in terrestrial food chains, which is essential from an ecological standpoint.

What Makes an Ungulate an Ungulate?

A hoof makes an ungulate an ungulate. The term “ungulate” refers to any mammal with hooves, with a hoof being an enlarged toenail in the literal sense (see below). In reality, however, the term “ungulate” has been applied in a variety of ways. After being used to describe two distinct Mammalian orders, Artiodactyla (even-toed ungulates) and Perissodactyla (odd-toed ungulates), it has now been extended to encompass seven different current Mammalian orders, some of which have no hooves at all!

A presumption of familial ties was used to justify this expansion of the term, which has now been revealed to be a fabrication based on subsequent scientific discoveries. This has resulted in the recognition that the ungulate does not have any taxonomic importance. The term’s definition has been restored to its original descriptive roots: an animal that walks on its hind legs.

What is the Difference Between Even and Odd-toed Ungulates? Or  How to Identify an Odd or Even Number on the Hoof?

The most apparent distinction between these two types of hoofed animals is the number of toes on their hooves that are capable of bearing weight. Odd-toed ungulates are animals that walk on one, two, or three hooves and are classified as zebras, horses, rhinos, and tapirs.

Ungulates with even-toed hooves comprise most of the world’s hoofed animals, including bovines, antelopes, warthogs, and many different pigs and sheepOpens in a new tab.. Even the hippopotamus is placed into this group, albeit only when viewed from a distance.

It is clear that even-toed ungulates have a significant numerical advantage over their single- and triple-toed counterparts in terms of population size. There are just 17 species of perissodactyls (odd-toed ungulates) surviving on the face of the planet.

Artiodactyls are a different story. There are nearly 220 species of artiodactyls (even-toed ungulates) on the planet, and 24 of them are regarded to be at risk of extinction.

Differences in Digestion

Even though they have the same number of toes, the digestive systems of these two types of animals are vastly different. Odd-toed ungulates are hind-gut fermenters, which implies that bacteria in the colon assist the animal in breaking down and digesting plant food.

Almost all of the even-toed ungulates are ruminants, which means they have a sophisticated multi-stomached digestive system capable of efficiently digesting plant material that would otherwise cause significant digestive problems in perissodactyls. They’re all chewing the cud together. More information about the ruminant digestive system may be found here.

Mechanisms of Self-Defense

Even-toed ungulates are more likely to have horns than odd-toed ungulates, which are more likely to lack them. Rhino horns are not horns in reality; instead, the word’s traditional meaning has been instrumental in eradicating the rhinoceros.

Survival of the fittest

It is undeniable that the even-toed ungulates are on the verge of winning the survival race. However, there are some additional fascinating aspects to each of these sorts of creatures that are worth noting.

Some of the least vulnerable species on the planet have evolved to be beneficial to humans, such as horses, cattle, sheep, pigs, goats, and camels, to name a few examples. Among the most endangered are being methodically exterminated by a single species that wander the ground on five toes and doesn’t chew the cud, as described above.

Why is a Dolphin Ungulate?

Dolphins are classified as ungulates since they descended from the same progenitor as artiodactyls around 60 million years ago. Dolphins are classified as ungulates because they are closely related to artiodactyls, a kind of dinosaur (even-toed ungulates). Cetaceans descended from an ancestor with even toes, which was an ungulate. Some have proposed that the mammalian order artiodactyls should be merged with the cetacean order Cetartiodactyla to reflect better the close link between these two groups of creatures. This modification has gained widespread acceptance.

Are Camels Cetartiodactyla?

Yes camels are cetrtiodactyla. Camelids (Tylopoda) are divided into just one family, Camelidae, which is found in the order cetriodactyla. A suborder of artiodactyls with few species, it is thought to have originated in North America. It is well adapted to extreme environments, as evidenced by the presence of the dromedary and Bactrian camels in Old World deserts and the presence of alpacasOpens in a new tab., guanacos, llamas, and vicunas in South American high mountain regions.

What Makes an Animal an Artiodactyla? Or What is the meaning of Artiodactyla?

Artiodactyla is an order comprised of animals that have four functional (weight-bearing) toes that are arranged in a spreading foot pattern. Usually, there are no hooves, but the nails at the ends of the four toes are sometimes expanded to give the appearance of hooves. In addition, most artiodactyls have extended metapodials that, except pigs, are fused to form a single functional unit.

What is the Order of Artiodactyla?

It is one of the biggest mammal orders, with more than 200 species, a figure that may be considerably decreased as the taxonomy of these animals is continually revised. Humans are familiar with many artiodactyls, and the order as a whole provides more economic and cultural benefits than any other group of mammals. People are largely negatively affected by the Rodentia order, which is considerably larger than the order of rats (Rodentia), which competes with them or impedes their economic and cultural growth.

Are Artiodactyls Herbivores?

Yes, some of them are herbivores (the suborders Tylopoda and Ruminantia, and the hippopotamuses, which are related to whales). In contrast, others are omnivores (the suborders Tylopoda and Ruminantia, and the hippopotamuses) (the suborder Suina). The Artiodactyla animals are distinguished by both upper and lower incisors and tusks (large, continuously growing canines).

What are Even-Toed Ungulates?

Even-toed ungulates are any member of the mammalian order Artiodactyla, including pigs, hippopotamuses, peccaries, camels, chevrotains, deer, giraffes, antelopes, pronghorn, sheep, goats, and cattle, among other animals.

What are Three groups of Even-Toed Ungulates? Or Tthe different types of Even-Toed Ungulates

Artiodactyls, often known as toed ungulates, are classified into three suborders. Suiformes is a group of animals that comprises the suids, tayassuids, hippos, and several extinct species. This group of mammals does not ruminate (chew their cud), and their stomachs can range from basic and one-chambered to complex and three-chambered in design. Their feet are typically four-toed (but at least slightly paraxonic).

They feature bunodont cheek teeth, as well as canines that are tusk-like in appearance. The suborder is referred to as Tylopoda is made up of only one surviving family, the Camelidae. Tylopods have a three-chambered stomach that allows them to ruminate. Their third and fourth metapodials are united in the vicinity of the body, but they separate distally, resulting in a Y-shaped cannon bone. This primordial state distinguishes tylopods from the third suborder, Ruminantia, as the reason for separating the cuboid and navicular bones of the ankle.

This final suborder comprises the families Tragulidae, Giraffidae, Cervidae, Moschidae, Antilocapridae, and Bovidae and several extinct groups. Tragulidae: Tragulidae is the ancestors of the Cervidae, which are the ancestors of the Cervidae. The absence of upper incisors, often (but not permanently) reduced or absent upper canines, selenodont cheek teeth, a 3- or 4-chambered stomach, and third and fourth metapodials that are frequently partially or wholly fused are all characteristics of this suborder, in addition to fused naviculars and cuboids, among others.

Are Giraffes related to Camels?

Yes, both giraffes and camels are even-toed ungulates and have the same order, i.e., Artiodactyla.

What are Even-Toed Ungulates called?

Even-toed ungulates are usually known as Artiodactyl

Are Humans Even-Toed Ungulates?

No, humans are not even-toed ungulates because humans do not have hoofs.

What Animal did Giraffes Evolve From?

For years, some scientists hypothesized that the modern giraffe (Giraffa camelopardalis, right), which includes a handful of subspecies found throughout sub-Saharan Africa, descended from an animal that looked similar to the okapi, which lives in the heavy forests of central Africa and is related to the giraffe. Those findings, based on scientists’ examinations of bones from all three animals, are bolstered—and not simply because the neck bones of the giraffe and the okapi are similar in length to each other.

On Samotherium, for example, ridges and other characteristics that are evident on the okapi’s neck bones and absent altogether on the giraffe’s are generally present but smaller than on the okapi’s neck bones.

The okapi is the only living creature that is closely related to the giraffe at this time (Okapia johnstoni). The okapi has a body form similar to that of a giraffe, but it has a significantly shorter neck compared to a giraffe.

Are Giraffes and Moose Related?

Yes, both giraffes and moose are related because they are even-toed ungulates and have the same order, i.e., Artiodactyla.

Do Giraffes have Toes?

Yes, they have two toes on each foot, and each toe is covered with a hard casing called a hoof. They are herbivores (plant-eaters). Giraffe feet are the size of a big supper plate with a diameter of 30cm. These massive hooves prevent giraffes from sinking into loose sand despite their great weight.

Why do Giraffes have Hooved Feet?

Giraffes have hooved feet because they belong to the order Artiodactyla, i.e., even-toed animals. Their evolution makes them hooved feet.

Do Giraffes have Paws or Hooves?

Giraffes are even-toed ungulates, which means that they have two weight-bearing hooves on each foot. They are members of the order Artiodactyla, which also includes antelopes (cattle), goats (sheep)Opens in a new tab., caribou (moose), hippos (hippopotamus), and pigs (pigeons). They are unable to walk since they lack paws.

Do Giraffes have Cloven Hooves?

Yes, giraffe belongs to the family of grazing animals that have cloven hooves.

Characteristics of Even Toed Ungulates

Artiodactyls are the most varied and massive terrestrial animals still alive today, yet they are also the most endangered. Their 210 species make up the fifth biggest order of mammals, and they are divided into ten families, eight genera, and about 210 species. Artiodactyls display extraordinary variety in body size and structure, which is to be anticipated in such a varied collection of animals as they are.

The body mass of hippos ranges from 4000 kg to 2 kg, whereas that of smaller Malay mouse deer is just 2 kg. Giraffes may grow to be 5 meters tall, whereas smaller Malay mouse deer can grow to be 23 centimeters tall.

Unlike other dinosaurs, artiodactyls had paraxonic feet, which means that the plane of symmetry of each foot runs between the third and fourth toes. There is a reduction in the number of digits in all species due to the loss of the first digit (i.e., pollex), and many species have reduced-sized second and fifth digits due to this loss. On the other hand, artiodactyls’ third and fourth fingers are big and heavy, and they carry a lot of weight. Artiodactyla, which translates as “even-toed,” was given to them because of this pattern.

On the other hand, the plane of symmetry in perissodactyls (or odd-toed ungulates) runs through the middle of the third toe. In extant or extinct artiodactyls, the most extreme toe reduction may be found in antelope and deer, which have only two functional (weight-bearing) digits on each foot, which is the most extreme case.

Among these species, the third and fourth metapodials merge to create a single bone known as the cannon bone, which may be partly or wholly fused. There is also a reduction in the number of ankle bones in these species, and the astragalus becomes the primary weight-bearing bone in the hind leg of these species. These characteristics are most likely adaptations for running quickly and effectively.

What Animals are Cetartiodactyla?

Cetartiodactyla is a group of mammals that includes two orders of mammals that are outwardly highly distinct from one another and were formerly thought to be two independent monophyletic clades. Artiodactyla, a group of ungulates with even toes that includes animals such as cows (Bovidae), camels (Camelidae), and deer (Cervidae), and Cetacea, a group of mammals that are highly specialized for an aquatic lifestyle that includes baleen whales and toothed whales.

Artiodactyla is a genus that includes animals such as cows (Bovid). According to recent molecular data, the Cetacea descended from artiodactyl forebears, rendering Artiodactyla non-monophyletic unless the Cetacea is included. Cetartiodactyla, according to experts, should be the name given to the monophyletic clade that includes artiodactyls and cetaceans.

What are the Characteristics of Cetartiodactyla?

It is so named because the Cetartiodactyla bears their weight on their hooves (the nail of the toes) in such a way that the centerline runs through the middle digits of both of their middle digits ( III and IV). Because these creatures essentially survive on being able to run well, the method they balance themselves is essential when attempting to comprehend their existence. Both a “cloven hoof” with only two weight-bearing toes and a “spreading foot” with four digits are regarded as the two primary forms of foot anatomy. The third and fourth digits are fully developed in all cases, but the second and fifth digits are decreased or missing.

With regard to this group, the Cetaceans are a particular example because they have acquired such remarkable swimming abilities that their similarity to their terrestrial counterparts cannot be distinguished. When they are in frigid settings, they rely on modified feet known as flippers to go about and blubber to remain warm, which they obtain from their mother. They have also grown in size as a result of evolution. The blue whale has grown to such an enormous size that it is now considered the biggest animal to have ever existed. Dinosaurs, you’ve got it!

Geographic Distribution of Cetartiodactyla

With the exception of Antarctica, these animals have invaded all of the world’s oceans and lands. They are absolutely important for human existence since they have served as the foundation upon which all civilizations have been constructed throughout history. Humans would almost certainly still be hunter-gatherers in isolated groups all over the planet if this order of animals did not exist.

Reproduction of Cetartiodactyla

To protect themselves from predators, the animals in this order gather in huge social groups of females and young to protect each other. Male animals are larger than females and require more food; thus, they spend most of their time alone, only congregating for mating. Females give birth to young and care for them until they are old enough to be on their own. There are very few occasions when these creatures produce more than one offspring at a time.

Feeding Habits of Cetartiodactyla

The grass is consumed by nearly all of the species in this group. They have a big stomach and a sophisticated digestive system, which allows them to obtain the most nutrients possible from this minimal resource.

What is a Camel Related to?

Camels are related to Llamas, alpacas, guanacos, and vicugnas.

The Behavior of Even Toed Ungulates

Artiodactyls are gregarious in nature; however, some are solitary. People believe that living in big groups helps to enhance per-capita forage intake by reducing the amount of time spent searching for predators per capita. Gracious animals reap the benefits of enhanced predator detection and food intake as a result of their gregarious nature. But as group size grows, so does the degree of intraspecific rivalry among individuals within a given grouping. In many cases, herds are sexually separated, which may help to decrease intersexual rivalry for food resources. Evidence shows that in size-dimorphic species, variations in the length of the gastrointestinal tract between males and females may result in distinct food needs, thus limiting dietary overlap between males and females.

In the face of interactions with conspecifics and predators, artiodactyls have a variety of responses. Some animals employ displays to prevent fighting, which may involve posturing and vocalizing, among other techniques. Physical characteristics such as fur color, horns, antlers, or tusks are frequently used in posturing. A broadside exhibition or the use of piloerection are two ways in which artiodactyls might make themselves look bigger to their opponents (i.e., raising the hairs on their neck or back).

Some artiodactyls utilize a threat display to express their willingness to fight, even though most displays are designed to prevent direct conflict. In order to indicate their eagerness for a fight, suids clench their teeth. For artiodactyls, when physical conflict is necessary, horns, antlers, and tusks serve as effective protection weapons. Artiodactyls most commonly utilize these weapons while battling with conspecifics for mates or territory, rather than to protect themselves or their young from predators.

Many artiodactyl species move in response to proximate signals, such as photoperiod, in a manner similar to that of other endothermic creatures. These proximal cues serve as markers for a variety of ultimate variables, such as seasonal changes, which can have an impact on the quantity of pests, predators, and forage in the environment. Even while migration has significant costs, the advantages are typically worth it because they enhance individual survival rates as well as reproductive fitness in many cases.

Barren-ground caribou and Serengeti wildebeest, which traverse yearly lengths of more than 500 and 1700 kilometers, respectively, are two of the most well-studied examples of artiodactyl migration. Unfortunately, seasonal migrations of many artiodactyl species are triggered by the passage of time, whereas the temperature of the surrounding environment begins plant-growing seasons.

Care of Even Toes Ungulates

Even toed ungulates are mostly domesticated, and they must require proper care, maintenance, and diet. Every ungulate has different care requirements, so you must contact your veterinarian for appropriate advice depending upon the species.

Health Problems of Even Toed Ungulates

Artiodactyls are host to a wide variety of endo- and ectoparasites, which may be found in their digestive tracts. Many parasitic flatworms (Cestoda and Trematoda) and roundworms (Nematoda), and roundworms (Nematoda) spend at least a portion of their lives in the tissues of their artiodactyl hosts, which is a common occurrence. Artiodactyls are also susceptible to various parasitic arthropods, including ticks, lice, mites, fleas, mosquitoes, and flies, among other parasitic insects. Artiodactyls are also known to have multiple parasitic protozoa, including trypanosomatids, coccidia, piroplasmids, and a variety of Giardia species, among others.

The health of artiodactyls and the dynamics of their populations are influenced by a wide range of bacterial and viral diseases, among other things. Examples include brucellosis, which is caused by Brucella abortus, which affects many artiodactyls, and rhinderpest, often known as bovine plague, a highly infectious viral illness produced by a virus paramyxovirus (Morbillivirus) that is particularly widespread in ruminants. It is regrettable to report; however, that data shows that recent climate change is changing host-parasite dynamics throughout the world, boosting transmission rates between populations of conspecifics and hybridization rates between host-specific parasite forms, among other things.

However, despite the fact that artiodactyls may be hosts to a wide variety of harmful bacteria and protozoa, in conjunction with anaerobic fungus, these organisms are one of the primary reasons why artiodactyls have become so common and diversified in the modern world. Bacteria make up between 60 and 90 percent of the microbial population found in a ruminant’s gastrointestinal (GI) tract, and they are responsible for the breakdown of cellulose in the gut. A kind of bacteria called ciliated protozoa, which make up 10 to 40% of the microbial community in the rumen, aid in the breakdown of cellulose by feeding on carbohydrates, proteins, and bacteria.

Although anaerobic fungi have been found in the rumen since the early 1970s, it has only recently been discovered. These fungi make up between 5 and 10% of the rumen’s microbial population, and it is assumed that they aid in the breakdown of plant cell walls that have been eaten. In the gastrointestinal system, bacteria and protozoa that move from the upper to lower regions provide a major percentage of the dietary nitrogen required by their host.

Where do Even-Toed Ungulates Live?

The majority of even-toed ungulates dwell in open environments, such as grasslands, although many also survive in wooded areas, while hippos prefer to live in or near water sources. Many are well adapted to sprinting; among the fastest terrestrial mammals are even-toed ungulates, which are among the most agile

Interesting Facts about the different types of Even-Toed Ungulates

All even-toed ungulates exhibit some degree of sexual dimorphism, with the males being consistently bigger and heavier than the females in size and weight. When it comes to deer, only the males have antlers, and when it comes to cattle, the horns are generally tiny or nonexistent in females. Male Indian antelopes have a significantly darker coat than female Indian antelopes.

Almost all even-toed ungulates have fur, with the exception of the hippopotamus, which is almost entirely hairless. The length and hue of the fur vary depending on the environment. Species living in colder climates have the ability to shed their coat. Camouflaged jackets are available in various hues, including yellow, gray, brown, and black tones.

Final Thoughts

Artiodactyls are the most abundant big terrestrial animals on the planet today, with more than 220 different species. They are also extremely important to humans in terms of nutrition, economics, and culture. Domestic species, in particular, are greatly sought after for various purposes, including food, fur, milk, fertilizer, medical goods, and draught animals. Additionally, wild animals like antelopes and deer give food and opportunities for sporting shooting and contribute to the wonder of nature. Wild artiodactyls play critical roles in terrestrial food chains, which is essential from an ecological standpoint.
