Human beings have spent centuries studying animal behavior. Ethology, the scientific discipline devoted to this subject, aims, among other things, to distinguish whether animals think or not. Humans generally assume that the main difference between animals and humans is the level of intelligence, but is this...
All life as we know it began in water. While it is difficult to prove, evidence suggests that gills existed before lungs. It is not that breathing with lungs is better or worse than breathing through gills. These different methods of animal respiration exist because of the different environments in which they...
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, the activities performed and the needs of the specific species. Additionally, did you know that there are some animals that don’t sleep much?
For...
In a previous article, we looked at the animals that sleep the most. Often because of a 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...
You have probably heard about birds that ‘head south’ for the winter, or seen videos of hordes of wildebeest travelling across the Serengeti.
