Animal fun facts

Reproduction is a fundamental process for all animal species on our planet. Without it, there wouldn't be any animals left to populate it. For it to take place effectively, reproduction has to adapt to each specific animal. This is due to various factors, including morphology and habitat. The result is...

There are many species of cetaceans, which are divided into two major groups: Mysticetes, which have beards, and Odontocetes, which have teeth.

Seasonal changes are common in most ecosystems, and in some cases they can be very extreme. Animals are often affected by these changes as temperature and precipitation cycles change throughout the year. These changes affect, among other things, the animal's ability to reach food or water. For this reason, cold-blooded...

We know that cats do not show love to their guardians in the same way humans do with each other. They cannot speak verbally with us, so they have to rely on body language and other forms of communication. When we see them rubbing their face against us, it is a clear sign of affection or perhaps a petition...

It is one of the reasons we can see a mouse has eaten through food packaging, since they can smell the food...

When we talk about squirrels, we are referencing animals of the Sciuridae family. While many of us will immediately think of a bushy-tailed red squirrel running up a tree, we should know the diversity of this family is great. In fact, there are so many different rodents in this mammal family that they...

When we discuss mammals, it is common for us to think of terrestrial animals. For this reason, many of us still confuse some aquatic mammals for other vertebrate animals. This can be seen when people confuse whales as fish. However, if we look closer at marine mammals, we can see they have the fundamental...

Raccoons are native to North America, similar in size to a small dog. Although they are mammals in the order Carnivora, they have a truly omnivorous diet. Thanks to human settlements developing in their natural habitats, raccoons are coming into contact with human populations more frequently. This is often due...

Their habitats range over large areas from north to south of the region, making it a mammal with one of the widest distributions of the entire Northern Hemisphere. Such large distribution means it has been given various names by various communities....

Although Australia can have a sometimes inhospitable climate, its relatively small human population means there is much space for its animal life to develop. This has led to a great diversity of animal species. One of the most adorable animals we will find in Australia is the wombat. However, beyond...

Both aquatic and terrestrial species of turtle are found in the order Testudines. They are easy to distinguish from other reptilian animals due to their carapace, an extension of their ribcage which helps protect their bodies underneath. Turtles need this protection as they are relatively slow-moving...

If we were to ask you about jumping mammals, the first animals which come to mind may be kangaroos, gazelles or even rabbits.

A common phenomenon in domestic cats is sitting by a window and make a chattering sound. The exact reason for this sound is unknown, but it occurs when they see potential prey.

Arthropods are the most diverse group of organisms on the planet, accounting for around 80% of all living animal species. Each individual species has adapted to their environment in certain ways. Some fly, some have long bodies and some have appendages which allow them to survive. The latter example can be...

Some animals are almost defined by a certain characteristic. While this can be somewhat reductive, the reason it happens is because these animals may have a feature which is so unique, we can't help but associate them with it. Such is the case with the giraffe. There are many fascinating facts about giraffes...
