You have probably heard about birds that ‘head south’ for the winter, or seen videos of hordes of wildebeest travelling across the Serengeti. In fact, many animal species make long annual journeys, for a variety of reasons and in very different regions across our planet. Although we don't always understand...

The color of an animals skin and coat are one of the many characteristics which allow us to distinguish one species from another. Our fascination with the colors and coat patterns is seen throughout history, in particular with art, design, textiles and many other industries. However, there are some animals...

All living beings on this planet need to reproduce to perpetuate their species, but not all animals reproduce in the same way. Moreover, not all individuals of a species will reproduce. This is either because they don't have the opportunity or they were never intended to do so. For example, animals within...

In a previous article we have looked at the animals that sleep the most. Often due to slow metabolism, these animals need a lot of rest to conserve their energy and survive. On the other hand, some animals seem to never sleep or at least we have seen little evidence of it. But are there animals that don't sleep?...

Did you know that there are some animals that are capable of sleeping more than 20 hours in a row? These long sleep patterns are related to factors such as food, performed activities and needs of the specific species. Additionally, did you know that there are some animals that don’t sleep much? For...

A common ancestor is believed to link the animals together, but some zoologists and taxonomists disagree...

All living beings need to adapt to their environment to survive. These environments are as wide ranging as life itself, whether underwater, above ground or even in the body of another living being. Helping to better understand these types of adaptations, we can group them as either physiological, structural...

Transgenic animals are animals that have been cloned. The medical and biotechnological uses of animal cloning are almost innumerable, as many diseases have been eradicated thanks to the production of these transgenic animals. Due to the controversial concept of cloning and scientific testing on animals,...

Fish experience reproduction in one of two ways. These processes include fertilization inside or outside the body. Fish are either ovoviviparous, viviparous or oviparous. Additionally, it is important to note that reproduction can also change according to the fish’s environment, specifically if it lives in...

In nature there are several reproductive strategies one of them being oviparous. You should know that there are many animals which follow this reproductive path, these animals also appeared much earlier in evolutionary history than viviparous animals. If you want to know what oviparous animals are, find...

Within the great group of viviparous we find different reproductive strategies, each holding different names. In this AnimalWised article we are going to explain them and explore certain facts which are worth knowing. We aim to make clear the difference between viviparous animals and mammals. In general,...
