The physiological, hormonal and behavioral functions of the vast majority of animals (including us humans) are governed by daily rhythms lasting approximately 24 hours. In this way, the body is able to tell us when we should sleep and rest and, on the contrary, when we should be awake and meet our main vital and energy needs. This curious phenomenon of nature allows us to classify the different fauna species, either as nocturnal animals, or on the contrary, as diurnal animals. Animals are rarely active all the time, but are able to alternate moments of great activity with periods of rest. Depending on at what time of the 24 hours a day the animals are engaged in one or another activity, we can clearly differentiate them and know if they are nocturnal or diurnal.
Continue reading this Green Ecologist article and you will discover more characteristics and examples of nocturnal and diurnal animals with list and photos.
Without a doubt, the main characteristic that defines the various nocturnal animal species it is his habit of being more active at night.
It is between sunset and sunrise, when the animals meet their main nutritional needs. For this reason, each and every one of the groups of nocturnal animals have developed different skills and strategies throughout their evolution to achieve greater success as nocturnal animals. Let's see some of the characteristics of nocturnal animals more details:
Take note of some examples of nocturnal animals with this list made up of the different large groups of animals:
It should be noted that the vast majority of nocturnal birds are also raptors or birds of prey.
Here you can see the images of nocturnal animals of these lists.
Diurnal animals, on the other hand, are characterized mainly by carry out your vital activities during daylight hours, between sunrise and sunset.
Their instincts, based on an internal biological rhythm called the circadian rhythm, are what drives these animals to develop their activities with sunlight and all those other stimuli that nature provides them during the daytime hours. Later, they will spend the night sleeping and recovering energy, always trying to go unnoticed among possible predators.
Some characteristics of the most common diurnal animals and that, therefore, all these species share are:
This is one daytime animals list with examples of the different types or large groups of animals:
As we have been detailing in the previous sections, the main difference between nocturnal and diurnal animals lies in the hours of the day They dedicate these for the development of their main vital activities, being between dawn and dusk in the case of diurnal animals and during sunset and sunrise for nocturnal animals.
This temporary organization, both of the behaviors and of the different physiological processes of animals, it allows them to be easily differentiated into animals with daytime or nocturnal activity. However, the specific mechanisms involved in circadian control (from the internal biological clock) of the daily rhythms that differ between diurnal and nocturnal species. For this reason, currently, there are many scientific studies focused on accurately defining these physiological mechanisms that differentiate nocturnal and diurnal animals.
