Live Wilderness Adventure

A rather novel combination came out of Bi Fang's mouth.

Poisoning black bears?

[What are you poisoning? Ah]

[Finally, the fact that Boss Fang is an alien can't be hidden?]

[One thing to say, compared to aliens, I believe that Lao Fang has performed some kind of surgery and installed poison glands (funny)] [I know, bitten by a spider and turned into a 400 aunt!]

[I don't ask anything else, I just want to know one thing, where does this venom come from, I'm curious and want to know (dog head)]

"How could it be that I produced the venom, of course I used it." Bi Fang was choked by the barrage, and Yuyu's mood was much better. Sand sculpture netizens always bring joy.

Survival in the wilderness with an audience and one without an audience are two completely different things.

At least being alone in the forest doesn't feel lonely, and even brings a little joy.

When the survival skills in the wilderness reach a certain level, what people confront more is not the problem of survival, but themselves.

Walking into the depths of the forest, Bi Fang continued to introduce: "In nature, in order to survive, various animals have evolved different survival strategies, either for predation or for self-protection, especially poisonous snakes, with their venom, Almost everything can be done with a small amount of money.

In nature, body size is almost the relationship between superiors and subordinates, but venom can allow animals to overtake and reverse this rule.

"However, it should be the poisonous species that humans are most afraid of, because most venoms are not only extremely painful, but we know very little about them, so there is an inexplicable fear."

All the behaviors of animals and plants on earth can be solved by: survival and reproduction.

The reason why animals and plants have evolved toxicity is actually for better survival and reproduction.

"According to the second law of thermodynamics, in an isolated system,

"D-

_1=The system will gradually change from order to disorder, which is the process of entropy increase.

Procedure. For example: an apple falls on the ground and will gradually rot. "

"Organisms want to survive, they first need to resist the increase in entropy, and the intake of energy can maintain the original low-entropy state, such as eating.

"All living things on earth must rely on energy to survive, but different living things use energy in different ways. Plants use solar energy, herbivores use plants, and carnivores use herbivores. Meat."

Energy flows along the solar-plant-herbivore-carnivore chain, which is why such a complex biological chain is formed on the earth.

But the theory is the theory, and every creature is reluctant to give up the energy that it has finally obtained.

"For plants, due to the limitation of cell walls, plants cannot move freely, and plants cannot fight back against each other, so they can only evade attacks from herbivores by evolving thorns and toxicity.

"And herbivores have more ways to avoid the attacks of carnivores. They can evolve faster running speed, sharper monocular vision, thicker skin, etc. to avoid the attacks of carnivores, but there are also some herbivores that will Evolved poison to fight natural enemies.

"There are also some animals that will evolve poison for hunting, such as: poisonous snakes, when they hunt, they will spray venom on each other first, wait for the other party to be poisoned and die, and then come to eat each other."

It is precisely because animals and plants need to better avoid predators and hunt better, so there are so many poisonous animals and plants in nature.

If the predator and the prey are regarded as the hunter and the prey, then there will always be an arms race between the hunter and the prey.

Both sides are constantly adapting to each other.

Having said that, Bi Fang's meaning is already obvious.

[Looking for plants or animals?]

[Is it hard to find poisonous plants? There is also a blood clover tree here?]

"There are many poisonous plants in Japan, but in terms of hunting, plant toxins are often not as good as biological toxins, like cycads." Bi Fang explained.

Cycad is a relatively common and highly poisonous plant in southern Japan. What many people don't know is that this plant is highly toxic. It is the oldest surviving seed plant on earth, the famous "living fossil" plant.

Its origins can be traced back to about 300 million years ago, reaching its heyday in the Jurassic era, when it dominated the earth with dinosaurs.

"Cow eats cycads japonica seeds, which can cause paralysis and are neurotoxins. Eating too much can cause death, but it's not enough to deal with black bears.

With toxins, most of them are smeared, and then attacked, entering the opponent's blood.

The biggest feature is that the toxicity is strong enough, the effect is fast, and it can cause the maximum damage with the smallest amount.

Talking about toxins without talking about the dosage is a hooligan. The cycad toxin infection caused by a few wounds is of no use at all, and the onset of action is slow.

"Just as there are only a few people who see the blood-sealed throat tree, but most of the poisonous animals can kill the prey of the same size with one blow. The useful plants that can be found here in Japan are probably only castor and water hemlock. The former is almost meaningless. The latter effect is not bad, and having children is listed as the most poisonous plant in North America, which can be used as a backup."

The toxin of water hemlock is so strong that the entire plant contains toxoplasmin, which can damage the central nervous system, causing seizures and eventual death in those who eat it by mistake.

And the effect of hemlock is similar to curare, which can paralyze the motor nerve, inhibit the medulla oblongata center, and has a quick effect.

However, what he was looking for more was a snake.

Plant toxins are all used for defense, to make herbivores afraid of them, only snake venom is used for offense, and the evolutionary direction is also based on Bi Fang's needs.

After all, it's all hunting, and the requirements are exactly the same. W

"Japan's humid climate provides habitat for as many as 47 species of snakes, but only eight of them live on the four islands of Hokkaido, Honshu, Shikoku and Kyushu, and there are only two venomous snakes."

"One is a Japanese pit viper, and the other is a tabby-necked snake. Due to the size of the black bear, we don't need toxins to kill it directly. As long as it has an obvious paralyzing effect, it is effective. What I'm looking for most , is the tabby-necked snake."

The venom of the tabby-necked snake is very low, with an average venom of 11.8 mg. The venom is mainly composed of metalloproteinases such as thrombin. But the intravenous toxicity is very strong, and the intravenous LD50 is 0.265mg/kg, which is more than the vast majority of Viper poisons.

Viper, most people can think of highly poisonous when they hear the name, and it can surpass most Viper families, which is evident.

However, because the tabby-necked trough snake is a poisonous tooth in the posterior groove, and whether it is a poisonous snake has caused a lot of people's discussion.

Because its fangs and venom glands are not connected by ducts, it is difficult to inject venom. When the venom is actually injected, its venom delivery system will be very wasteful. Coupled with its docile personality, most people are bitten by tabby. thing.

Before 2008, it was not even considered a poisonous snake in Huaxia.

But even so ~www.readwn.com~ tabby-necked trough snakes have several fatal bites in Japan.

"But it doesn't matter, I extracted it artificially, and I won't let it go to waste. In fact, during the earthquake yesterday, a lot of poisonous snakes came down from the mountain. Once the jadeite is found, there is no time to catch it."

Reptiles are very sensitive to earthquakes. At least a dozen snakes passed by Bi Fang's line of sight at that time, but they were all eager to escape and did not pose any threat.

"Let's go over there now to see if we can find it, and it mainly preys on small vertebrates, such as frogs and toads, and likes to inhabit places with lush water plants, and in the same place as water hemlock, what we are looking for It's actually two things."

Bi Fang walked in the direction he had imagined, and soon found a creek in the valley, and then searched along the creek.

During the period, the tabby neck groove was not found, but two entangled belly chain snakes were found, belonging to non-venomous snakes.

No waste, Bi Fang took the loving couple together, prepared to make today's lunch, and then searched. In the end, Bi Fang found the target in the middle of the water plant in Xiaocong.
