Crepuscular animals - Definition and 5 examples

The spatial and temporal characteristics of the medium have put pressure on organisms, resulting in the different ways of life that we know today.It is easy to understand that a living being occupies a physical ecological niche, for example, in the marshes we can see how many species of herons, spatulas and limicoles are fed, that It is their ecological niche from where they obtain food and most likely shelter.This will also be the niche for feeding eagles, eaglets or hawks.

On the other hand, otters also have the same ecological niche as the animals mentioned above., but we will never see them together, because they live in different time zones or in other words, when these birds go to sleep the otter goes out to hunt fish and crustaceans, they feed on the same resource but do not compete for the time because the ecological niche tempora l is different.

This is one of the advantages of crepuscular animals and, therefore, in this article of Animals and Pets Online we will explain what they are and give some examples.

What are crepuscular animals?

Twilight animals are those that enter into activity during sunset and/or sunrise.This type of behavior, like being diurnal or nocturnal, is regulated by the biological cycles inherent in each species.

Twilight animals gain certain advantages because of their lifestyle.In desert climates they protect themselves from the high temperatures of the day and the low temperatures of the night, since they leave just at the moment when the ambient temperature It starts to oscillate.

They are more protected from being hunted by diurnal predatory animals if we take it for granted that the predator has already got food during the day.When a twilight animal leaves its shelter they will not have done so yet.nocturnal animals.

During the hour at which these animals begin their activity, the sun's rays affect the earth's surface in such a way that it is more complicated for both a daytime predator and another nocturnal predator to detect its pr those.

Cardiac rhtyms

To better understand the biological cycles of crepuscular animals, we will talk about circadian rhythms.Chronobiology is the discipline that studies biological rhythms, describing both their temporal characteristics and their implications for life.A biological rhythm is an oscillation of a biological parameter that depends on the endogenous clock (physiology and genetics) and environmental synchronizers (variations in the environment).

Then, there are different types of biological rhythms:

Circadian rhythm: biological activity that occurs with a periodicity of approximately 24 hours.According to this cycle, diurnal, nocturnal and crepuscular animals will appear.
Ultradian rhythm: biological activity that occurs in cycles of less than 20 hours (for example, feeding).
Infradian rhythm: biological activity whose frequency is greater than 24 hours, that is, they occur less than once a day (for example, lunar cycles).

Examples of crepuscular animals

Many animal species lead this twilight lifestyle either by living in climates, avoiding predators or not having to compete for certain resources with other species.Below we show some animal species with crepuscular habits:

Gila's monster (Heloderma suspectum): this reptile is the largest venomous lizard in the United States, it only comes out of its lair when the sun goes down, sometimes it can be days and weeks without going out and only It will do so if the weather becomes rainy.The striped skunk (Mephitis mephitis) is another twilight species.During the day time passes in its burrow, but at dusk and dawn it goes in search of food.a very calm animal that tends to ignore other animals, but if it feels threatened it will spray a pestilent liquid on its attacker.The European otter ( Lutra lutra ), difficult to see and very elusive, has its beak activity during twilight.The field rabbit ( Oryctolagus cunicu lus), although it can be seen during the day when the temperature is hot, they are crepuscular animals.This allows them to avoid some aerial predators, like the eagle.The wild cat ( Felis silvestris ), very similar to the common cat, like this one, is of crepuscular habits.In the Iberian Peninsula there are several subspecies of wild cats, all of them with the same habits.
