The strongest sense of smell among animals

The bear

It is believed that the bear has the strongest sense of smell among all animals, and despite the small size of the bear’s brain, which is approximately one-third the size of the human brain, the area responsible for its sense of smell is five times that of the human brain, and therefore its sense of smell is superior to its sense of smell. Human smell is 2100 times greater, which helps the bear avoid danger, track the location of its companions and prey, and the location of food, as it can smell animal corpses from 20 miles away.^[XNUMX]

The shark

The shark can smell a single drop of blood in 100 liters of water, and it can locate its prey from a mile away, which makes it easier for it to find any injured marine animals or humans within its search area, and the reason for this is due to the large size of the area. Responsible for his sense of smell in the brain, which is approximately two-thirds of the total area of ​​it, and the nose of the shark is often located on the underside of the snout, with the exception of some of them, such as the nurse shark, which is distinguished by having sensory nasal ligaments next to both the nostrils and the mouth, which help In the processes of tasting and feeling.^[XNUMX]

the elephant

The African elephant has about 1948 genes responsible for detecting odors, which is the most in the animal kingdom. Elephants can explore water from 12 miles away, and thus it has the most reliable sense of smell under water. Its trunk also contains a large number of olfactory receptors. And other uses.^[XNUMX]

The cat

The Journal of Applied Science of Animal Behavior published a study comparing the sense of smell in cats and dogs, and showed that it is stronger in cats than in dogs, and studying their genes helped reveal that they can distinguish more smells than their rival dogs, starting with the smell of humans to the smell of explosives, and the smell of Some diseases such as cancer, tuberculosis, and many more.^[XNUMX]
