Quadrupeds - Examples of Four-Legged Animals

We too often rank animals by speed or certain abilities without giving them the correct context. Some animals may be faster than others, but this is only because they have needed to adapt in the way they have. What is more important and more interesting is looking at how and why animals do the things they do. Movement is one of the most important factors. For quadrupedal animals, using four limbs can give them both many advantages, as well as certain disadvantages in their given environments.

At AnimalWised, we bring you our list of quadrupeds with examples of four-legged animals. We explain the characteristics of these animals and show you both what makes them similar and what makes them different from each other.

What are quadruped animals?

The term quadruped refers to four-legged animals. They use these limbs to move from one place to another and are, generally speaking, terrestrial animals. There are marine animals which spend a lot of their time un water, but if they are a quadruped, they also can walk on land. Examples of these semi-aquatic quadrupeds include otters, sea turtles and alligators.

An important distinction to make with quadrupeds is that not all of them are tetrapods. Some may think that birds have four limbs since they have wings which allow them to fly and some can even manipulate their environment with them. However, they do not use all four limbs for locomotion. In this way, although birds are tetrapods, they are not quadrupedal.

Characteristics of quadruped animals

Although they encompass many different taxonomic groups, quadrupeds have certain characteristics in common. All quadrupeds have the following:

  • They have two front and two rear extremities on which the weight of their body rests. In some cases, this makes the body mass evenly balanced between all four limbs. In others, more than half the weight can be supported by the front or rear legs.
  • When moving, at least one of the legs is always resting on the ground.
  • The movement of the forelimbs and hindlimbs occurs in a synchronized manner, allowing the animal to move in a coordinated motion.
  • Although there is a range of footprint patterns, each group of quadruped footprints is evenly spaced.
  • Quadrupeds have greater variety in the dynamics of travel than bipeds.
  • Their symmetry is bilateral, creating the sagittal plane which divides the right and left sides. This symmetry is closely linked to its cephalization (the sense organs being located at the fore of the body).
  • There is a frontal plane that divides the body of quadrupeds into dorsal and ventral, while the transverse plane does it anteriorly and posteriorly.

Quadrupeds are divided into different areas of the body which are given the following terms:

  • Anterior: the head.
  • Posterior: the rear or tail.
  • Dorsal: back or upper side.
  • Ventral: belly or underside.
  • Medial: the longitudinal midline which rungs along the body.
  • Lateral: for each of the sides.
  • Pectoral: chest area supported by forelimbs.
  • Pelvic: hip area supported by hindlimbs.

Examples of quadruped animals

Now we know the traits which characterize quadrupeds, let's take a look at some examples of quadruped animals:


They are animals belonging to the order of Proboscidea and are the only current family of this group. The elephant is a clear example of a quadruped animal that moves on four legs. They are largest terrestrial animal in terms of weight, so the four-legged conformation of their body is vital for proper support.


Horses are vertebrates of the order Perissodactyla, belonging to the equine family. They move on all four limbs and can reach great speeds when running. In addition, they manage to sleep standing up, thanks to the anatomical configuration of their four legs.


From a taxonomic point of view, rhinos are included in the family Rhinocerotidae. Like elephants, they are among the heaviest land mammals on the planet, so they also require adapted legs to support up to more than a ton of weight. On the other hand, despite their mass, they manage to reach speeds of up to about 50 km/h.


These big cats are considered one of the fastest land mammals. They usually weigh just over 70 kg, they are thin and have long limbs compared to their. These traits conspire to give them the ability to reach such high speeds with all four legs working in tandem for greater efficiency. Unlike other cats, cheetahs do not stalk their prey, but wait until they are at a safe distance to start a high-speed chase.

Gazelles are agile quadruped even-toed ungulate animals, belonging to the Bovidae family. With their long and thin legs they support a slim, medium-sized body weighing around 50 kg. They can reach speeds close to 100 km/h and maintain half of this speed for sustained times.


Giraffes are ruminant mammals and the tallest land animals in existence. These quadrupeds measure about 6 meters in length, allowing them to be visible over distances. It is a disadvantage, since they can be more easily discovered by lions, their main predators.

Take a look at our article on why giraffes have long necks to learn more.


Bears are mammals belonging to the Ursidae family. There are several species of bear that have quite dissimilar characteristics, such as coloration or method of feeding. However, a peculiarity of some of these quadrupeds is their ability to stand up on their two hind legs and take short steps like a biped.

Buffaloes are large bovines distributed throughout various regions of the planet and are some of the largest and heaviest quadrupeds. They can reach up to 500 kg in weight and there have even been specimens that considerably exceeded this amount. This means that they need legs capable of adequately supporting such weight.


Donkeys are another type of equine quadrupeds. These quadruped animals cannot reach the speeds of horses. They have been unfortunately used throughout history as pack animals thanks to their stability and safety when moving on their four limbs.


Dinosaurs are a type of extinct quadruped which cause fascination for many naturalists. Not all dinosaurs are quadrupeds, but those that are we know thanks to the fossil record. They are fascinating animals in terms of quadrupeds as we can see how some have evolved over time.
