Animals are most sensitive in what situations

The animal with the most sensitive sense of smell is the bear, the bear is considered to have the strongest sense of smell of all animals on the planet, although the brain of the bear is about one-third that of a human, the area of smell is five times the size of a human, and the bear uses this keen sense of smell to find food and companions and avoid danger.

Bears are a general term for mammalian carnivorous bears, bears are usually mild, but when threatened or in danger, they tend to get angry and fight very fiercely.

Bears are generally gentle, do not actively attack people and animals, and are willing to avoid conflict, but can also turn into very dangerous and fearsome beasts when they feel they must defend themselves or their young, food, or territory.

Most bears have a mixed diet, eating grasses, shoots, moss, berries and nuts, but also going to streams to catch frogs, crabs and fish, digging rodents, digging birds' eggs, preferring to lick ants and steal honey.

The most common animals with a keen sense of smell are the following:

Clause. 1. Dogs, dogs' sensitive sense of smell makes them have a stronger tracking function;

Clause. 2. Elephants, elephants' powerful sense of smell can compensate for the lack of vision;

Clause. 3. Weasel, the weasel's sense of smell is mainly reflected in resisting the stench released by itself.

The dog's sense of smell is very sensitive, so many times all kinds of delicate work need to train a special dog to do these jobs, such as training police dogs and so on. Dogs' sense of smell is millions of times more sensitive than humans' sense of smell, and the smells and distances they can smell are also incomparable to humans. So dogs can smell more than 2 million scents and can accurately distinguish them.

Dog. Therefore, humans have been training dogs, as hunting dogs, looking for traces of wild beasts, and can also be used as police dogs to understand the smell of criminals, and then further search to find clues of criminals. You can also be a drug detector dog to find the location of drugs.

Elephants perceive the outside world by their sense of smell. Because elephants have very poor eyesight, the main perception can only be the sense of smell. Elephants can distinguish different situations and animals according to different smells.

And this ability to discriminate can also be inherited, so that the offspring of the elephant will have an increasingly strong ability to discriminate.

Elephant. Weasels also have a very strong sense of smell, not only strong, but weasels can also defend themselves against enemies by emitting a very smelly fart.

Weasel.

It is not possible to generalize. Some animals are very sensitive to a single odor, such as sharks, which can smell the blood content of one part per million in seawater. Dogs, on the other hand, are all-rounders and are sensitive to a variety of smells.

Biomimicry experts have created odor detectors based on the principle of animal smell to detect the content of harmful gases in the air.

Upstairs is right, sharks do have a strong sense of smell. Japanese scientists have found that even if only 1 gram of amino acids are dissolved in 10,000 tons of seawater, sharks can sense the smell and gather together. However, it is difficult to domesticate, and there seems to be no means to use it at present.

The most used are of course dogs, especially military dogs. Explosive disposal, drug detection, and search and rescue are all inseparable from them. Canines have a 1 million times more sense of smell than humans.

Elephants also have a good sense of smell. Groundwater can be found with a sense of smell in times of drought. In India, elephants are useful helpers to humans, and in many wildlife sanctuaries, elephants are used as mounts to protect against other animals, and their sense of smell helps people find wild animals that do not have radio receivers.

In addition, pigs have the same sense of smell as dogs. Similarly, in the wild, pigs can use their sense of smell to find groundwater. In the harsh winter months, you can also find food buried deep in the snow.

As for who you say has the most sensitive sense of smell, I would like to have a personal opinion. Because there are differences even between individuals of the same species, scientific tests of this kind must be more or less biased. It's impossible to say exactly who is the most sensitive.
