Are bats nocturnal5/4/2023 ![]() They have many cone cells in the retina than rod cells that result in good color vision during daylight. Unlike nocturnal animals, the most well-developed way of sensing in diurnal animals is the vision. For example, many diurnal mammals are inactive during nighttime because their body temperature drops at night. These animals are well adapted to live during daylight. In addition, touch is also very important especially for nocturnal borrowers and some amphibians.Īnimals that are active during the daylight are called diurnal. The sense of smell is also a very important method to many nocturnal animals in order to find food, to find a mate and to smell pheromones of other animals. Some examples for nocturnal communication include the night call of waterfowl, hooting, and screeching of nocturnal owls, roaring of crocodiles, etc. Thus, they use sounds to communicate with their group members and outside arrivals into their territory. Nocturnal animals cannot use vision to communicate. Nocturnal animals like fennec fox, bats, bush babies, and lories have extremely large pinnae to collect even a small sound and to detect the location of the sound. Hearing is also an important method of sensing for nocturnal life. In addition to general sensory systems, many nocturnal animals are sensitive to infrasound, wind direction, air pressure, and on coming storms and earthquakes. For example, some frogs have skins which are sensitive to light, some snakes are able to sense heat, and the aquatic salamanders can detect even small movement in the water with the help of an organ. Many animals have developed at least one of their senses to a greater extent, but some have an additional sensory system. They are extremely well adapted to survive in the nighttime with the help of structural modifications of the body and powerful senses, such as vision, hearing, smell, etc. Nocturnal animals are the animals that are active during dark hours of the day. The differences between nocturnal and diurnal animals are further discussed in this article. Animals’ active hours vary widely with the availability of many factors as mentioned above. The animals that are active during dawn and dusk are called crepuscular. However, it should be noted that some animals are neither diurnal nor nocturnal. Nocturnal animals are the animals that are most active during the nighttime, and diurnal animals are the animals that are active during the daytime. Based on the activeness during a day (24 hours), animals can be classified into two types: nocturnal and diurnal. Thus, animals develop many adaptations according to their active hours. This is very important for the survival of animals. Various factors such as availability of food, competition for food, mating, and danger from predators influence the biological clocks of animals.
