ANIMAL CURIOSITIES
The sensory superpower of animals: eight species that see infrared light
The ability to perceive infrared light is a sensory superpower reserved only to certain animal species.
Although humans cannot see this part of the light spectrum, there are animals that can do so naturally. In this photo gallery, we will explore eight animal species that possess this unique and fascinating characteristic, and how this sensory ability helps them in their survival.
From seeing vampire bats to hunting mosquitoes, we discover how these animals see the world through infrared light.

Salmon
Salmon use infrared light to navigate the brackish, dark waters of the ocean during their mating migrations. The biochemical reaction in their eyes changes to help them see the near-red infrared spectrum. The natural production of an enzyme allows the salmon to transform vitamin A1 into vitamin A2 to facilitate navigation.

Viper
The viper uses "pit sensors" along its jaws to sense changes in infrared light. These sensors detect heat at the molecular level and send an electrical signal to the viper's brain. By combining this sense with traditional vision, the viper has a complete sense of situational awareness.

Goldfish
The goldfish has a visual range from the infrared spectrum to the ultraviolet spectrum due to its four colored cones in its eyes. These cones allow it to see food and threats in visible light as well as reflections in water. No other fish has such a unique sensory range as the goldfish.
Fox
Foxes and possibly other nocturnal mammals such as coyotes may be able to see infrared light, although this has not yet been scientifically demonstrated. However, it has been observed that these animals avoid hunting cameras that use IR technology to detect animals at night.

Mosquito
Mosquitoes can detect prey through their ability to sense the carbon dioxide emitted by their bodies, but also through their infrared vision. While the smell of carbon dioxide helps identify prey at a distance, infrared vision allows mosquitoes to get close enough to visually identify a target. Mosquitoes use a combination of these senses for hunting.

Vampire Bat
The vampire bat uses a sense organ similar to the pit sensors used by vipers to detect warm-blooded prey. However, the vampire bat's organ shape is more sophisticated and can detect the dangerous temperature and threshold for warm-blooded prey. Because of this ability to sense infrared light, the vampire bat is a highly specialized hunter.

Wolf
Wolves and other related canines may be able to perceive the infrared spectrum in a unique way. Recently, it was discovered that wolves and dogs can smell heat with their noses, which makes one wonder about the relationship between the infrared spectrum and mammals. Although dogs mainly rely on other senses, it is believed that they can be trained to better perceive heat, just as wolves use this ability in the wild.

American Bullfrog
The American Bullfrogs use an enzyme to convert vitamin A1 to A2, enabling them to see infrared light. Although they become primarily A1 pigments as they grow, they retain the ability to see infrared from below the eye while seeing visible light from above. Bullfrogs use this ability to search for prey above the water and potential predators below the surface.
Ferocious animals
28/04/2024
Anyone who is used to wandering in the woods and mountains knows that encountering a wild bear is a very unlikely experience. Bears are often frightened of humans and do not approach them, but if this should happen, what should one do?
Recently, in Italy, a boy unfortunately died as a result of a wild bear attack, but this is a rather rare and dramatic event. In any case, one can never be too careful, and it could be very helpful to know what to do in the event of an encounter with a bear, especially if you are out and about alone.
The US government has long since issued general guidelines on how to behave and how to react in the event of a close encounter with this huge animal, which is often just curious, but sometimes also very dangerous if certain rules are not followed.
