There are also some poisonous mammals in nature. They are petite and do not have strong bodies and the ability to move quickly, but their small bodies contain a huge amount of "energy". Don't be fooled by their cute looks. In fact, they are very dangerous.
<h1 class="pgc-h-arrow-right" data-track="2" > long-nosed "little mouse"</h1>
They look like rats, but have nothing to do with rats. They are mainly distributed in Haiti and Cuba. The body length is only 28 to 30 cm, and the tail length can reach 18 to 26 cm. It has a long nose and a keen sense of smell. The dorsal side of the two lower front teeth has a groove leading to the submandibular glands, and the saliva contains toxins that allow them to prey on larger frogs and lizards other than insects. Groove-toothed shrews inject venom in a similar way to venomous snakes. Since there are no large animals on the island, its keen sense of smell and deadly venom make it look very strong. However, due to the fact that humans also continue to occupy grasslands and woodlands, there are also climatic reasons. The living environment of the groove-toothed shrew has been greatly damaged. Since the 1860s, the population of the groove-toothed shrew has declined dramatically, and the IUCN lists it as a highly endangered species. The groove-toothed shrew has many other characteristics: its claws are large, which is not commensurate with its petite size; its mammalian organs are located at the back of the body near the hips, which is different from most mammals. According to the investigation of biologists, the genome of the groove-toothed shrew is very different from other mammals and has high biological research value.

Skunks are known for their ability to emit odors, but this is just one way for skunks to protect themselves. When a predator approaches the skunk, the skunk will raise its tail or touch the ground with its paws as a warning. If the predator continues to approach, it will immediately turn around and run and emit a smell. The skunk's odor has a wide range of effects. The skunk can be smelled from almost 100 meters away. So most carnivores avoid skunks. So how do skunks emit odors? It turns out that the skunk has two large skunk glands in its anus, which can produce a special "skunk musk", a toxic mixture of sulfuric acid and thiols. Animals that are "attacked by the smell" will immediately run away. If the eyes are contaminated with secretions, they will not only shed tears, but will also become blind for a short time, and the smell will stick to the fur for a long time. Skunks in nature generally live a long time because their smell protects them well. Other animals that release scents are weasels, foxes, pangolins, and other animals. In the case of prey and evasion of predators, the use of these poison gases can be very good at protecting oneself from harm.
<h1 class="pgc-h-arrow-right" data-track="6" > little monkeys who don't like to move</h1>
The loris is a rare and venomous primate. It likes to live in trees and rarely gets off the ground. Lorises do not like to move and only accelerate their movement when attacked, so they are called "lorises". Lorises are only 30 cm. Although it is small and slow, it has a unique skill to protect itself. Lorises are good at camouflage. Because they don't move much, they are often covered by lichens or algae, which makes them one with their surroundings. But the most serious is the toxicity of lorises. They can secrete a substance from the glands inside their elbows and spread the secretions throughout the body by licking. When they are threatened, they roll to the ground and shrink into a ball, exposing only their poisonous fur. Sometimes they will take the initiative and release venom to scare off predators. The mother of the lorisk will also lick the child and apply the child's secretions to protect the child from being eaten. Animals affected by loris secretions may have wound infections and body allergies, but they are not fatal. The loris is popular because of its small size and cute appearance. In recent years, it has been captured by a large number of humans. Due to human hunting and excessive predators, the number of lorises has been greatly reduced. We should be vigilant about this. They belong to nature and should not be our playthings.
<h1 class="pgc-h-arrow-right" data-track="8" > small hand to smear the poison on the body</h1>
Some small mammals cannot produce their own toxins, and they use external toxins to protect themselves. The hedgehog kills the toad, smears the toad's toxin on his spines, and shrinks into a ball in times of danger, exposing the thorns to scare away predators. There is also a species of African crown rat, which will eat the bark and rub the toxins on the tree on the fur.
Other mammals with toxins in their bodies include platypuses that live in water.
and vampire bats that live in caves. These venomous mammals live in a very secluded environment, which may be why they are able to store toxins in their bodies. Therefore, these mammals need to eat regularly to ensure the amount of toxins in the body.
