What is the most olfactory animal in the world

Silkworm. However, it is not the larvae of silkworms that are being talked about here, but the male silkworm moths. Male silkworm moths can distinguish the scent of female moths up to 10 kilometers away, and they are only a few centimeters long.

The animal with the most sensitive sense of smell has been found to be dogs.

In the animal kingdom, the canine nose is indeed the most sensitive, according to biologists, the dog's sense of smell is a million times more sensitive than that of humans, and it can smell thousands of substances. Military dogs can identify the road with their sense of smell, judge the enemy's situation, and track and pursue. When a hound smells a wild animal, it will hold its breath and stop and use its nose to determine the direction of the beast and assist the hunter in capturing it.

Before Tangshan in 1976, there were at least a dozen such incidents in the local area: dogs barked wildly to the sky and did not listen to the owner's command; sniff the ground and pick up pits, and don't lift your head; Running around with the puppies in his mouth, gouging the door and hitting the window, and not stopping for a moment. **That night, there was a wolf dog of a member's house, barking non-stop, affecting the owner's sleep, the owner beat it away, just lay down, the dog barked again, he got up again to chase, just out of the door,** happened.

**Before, a charged particle will be produced in the air, and the chemical elements in the ground will also change, producing a "ground smell", after the dog smells this special smell with a sensitive sense of smell, it will produce an abnormal reaction, inadvertently saving the life of the animal's sense of smell and the animal's sense of touch has nothing to do with it.

In the animal kingdom, the canine nose is indeed the most sensitive.

Among the large animals that can smell scents, bears are the best. Its sense of smell is 300 times better than that of humans. Since the olfactory bulb area in a bear's brain is five times larger than in a human brain, bears have the best sense of smell in the world.

This ability makes bears both frightening and fascinating. Bears have huge snouts, each with thousands of olfactory receptors. As a result, this species has one of the most sensitive sense of smell in the world.

Thanks to bears' special abilities and keen sense of smell, they are able to detect dead animals up to 20 miles away. When camping or in the forest, especially when bringing food that is attractive to bears, the main olfactory receptors --- 100 times more sensitive than the human nose --- sense the smell of the food they carry. If you don't put food in a deodorant plastic bag, it can be challenging to keep the bear away from your food in this situation.

Animals with the most sensitive sense of smell include: bears, elephants, kiwi birds, sharks, snakes.

1. Bear

Scientists believe that bears have the most sensitive sense of smell among the animals on Earth, and although the brain of a bear is 1 3 the size of a human, the olfactory area is 5 times the size of a human, and a bear has a 200 billion hundred times better sense of smell than a human.

2. Elephants

The elephant's sense of smell is arguably the most reliable, detecting water up to 12 miles away, and its nose has many receptors for sniffing and grasping.

3. Kiwi

It is a flightless bird that must find food on the ground, and it has a very sensitive sense of smell, and the one that attracts birds is the most sensitive of all birds.

4. Sharks

Among the spare forces, the shark's sense of smell is the most sensitive, and the great white shark has the most sensitive sense of smell among sharks. Great white sharks can smell a drop of blood outside of the town of Yiyingchun.

5. Snakes

Unlike other animals, the snake's sense of smell is its tongue. Different tastes can be identified with the tongue, odor particles are captured with the tongue, and then identified according to the organ.

Animals with a stronger sense of smell: Sirchichi bears, sharks, elephants, kiwi birds, snakes.

1. Bear

Bears are considered to have the strongest sense of smell of any animal on Earth, and although bears have brains about one-third the size of humans, their olfactory areas are five times the size of humans. A bear's sense of smell is 2,100 times better than that of a human, and bears use this keen sense of smell to find food and mates, avoid danger, and stalk wild cubs.

2. Sharks

Among sharks, one study showed that great white sharks have the most pronounced sense of smell. The sense of smell is controlled by about two-thirds of the shark's brain, which can smell a drop of blood from a distance of a mile, and its speed makes it a deadly predator.

3. Elephants

The African elephant has the largest number of odor detection genes at 1,948, the elephant's sense of smell is the most reliable, the elephant can detect water up to 12 miles away, and the elephant's trunk has many receptors, which are mainly used for olfactory and grasping, among other purposes.

4. Kiwi

Flightless birds, must find food on the ground. The tip of the beak has external nostrils that facilitate searching for food in soil and leaf litter. Among all birds, kiwi has a very important olfactory bulb, which gives the kiwi a strong sense of smell.

5. Snakes

Like a bear, a snake has an organ in its mouth, the snake can recognize different smells, the snake's sense of smell is highly developed and robust, it uses its tongue to capture odor particles and then identifies them according to the organ.
