Animals – The Most Common Animals in the World

Many articles have claimed that one animal is the most common, but that claim could have been due to availability bias. Also, it is hard to narrow down the most common species, and most studies don’t focus on this. The most common animals in the world vary greatly in size, shape, and type.


Ducks are beautiful birds that live in ponds and lakes around the world. They have a streamlined body and webbed feet that act as paddles to propel them through the water. They can swim in icy water thanks to their circulatory system, which has blood vessels close together in their legs and feet.


Rabbits are one of the most common domestic animals in the United States, and the family also contains other animals. As part of the Rodentia order, rabbits share common traits with mice, rats, and the marmot. Their digestive systems are complex, including the cecum at the head of the large intestine, which contains beneficial bacteria to break down the cellulose in plants. This is necessary for rabbits since they need to maximize the digestion of their vegetation, and they eat twice a day to ensure they get sufficient nutrients.


Orangutans are the common species of monkeys native to the Indonesian rainforest. They also consume a large variety of insects. As the rainy season approaches, these monkeys often use leaves as shelter. They also use leaves to make umbrellas and sponges. Although many people are familiar with chimpanzees using tools, few realize that orangutans can also fashion their own devices.


The social life of elephants revolves around breeding and raising their calves. Female elephants begin breeding around thirteen and communicate their intent to mate by sending smell signals and special calls. They usually prefer more extensive, stronger, and more mature males. The females give birth to a calf after a 22-month pregnancy, and the baby is between 113 and 76 centimeters in height.


Crocodiles are found around the world in both freshwater and saltwater environments. They are common in rivers, swamps, and lagoons and can even be found on small islands and live in groups of up to 100 individuals, though they can also be found in solitary habitats. They are excellent swimmers and can tolerate a saltwater environment.


Moose are large mammals with a range that extends across much of the North American continent. They have excellent hearing and sense of smell and are active at dawn and dusk. They are also a powerful swimmer and can stay underwater for up to 30 seconds.


Sloths are slow-moving mammals that spend much of their time in treetops, where they sleep and rest. These animals can spend up to 20 hours a day without eating, and their slow metabolism helps them avoid predators. They also use algae on their fur to camouflage themselves in trees.

African gray parrots

African gray parrots are native to Africa. They roost in palms and trees. They use their toes and beaks to balance themselves. These parrots are usually about seven to eight inches long and have black beaks and silvery gray bodies. They have zygodactyl feet, meaning they have two toes that face forward and two that meet back. Their tails are relatively short.

African elephants

Elephants live in herds and are among the largest animals on earth. They live in the forests of tropical Africa and have a complex social structure. The pack is led by an older, more experienced female who is considered the matriarch. The herd will usually consist of up to ten females. The matriarch will act as the matriarch and teach the younger elephants how to behave in elephant society. The younger females in the herd will often help with feeding and calf care. They will also provide allomothering to the younger calves.

Asian elephants

Asian elephants are found throughout Southeast Asia and India. Their highly developed neocortex helps them solve problems and form relationships. This trait allows them to adapt to changing habitats.
