My frog brought me food again... But my frog is still asleep... These days, many people complain: there are snowflakes outside the window, and there are toads inside the window! The frog in the popular Japanese game "Traveling Frog" is called "Buddhist frog" by players.
Indeed, in the game world, it does whatever it wants in life and travel, is alone, and looks down on everything... However, if you return to the real and cruel nature, this "Buddhist" personality will not survive at all. In order to adapt to various extreme environments, the "non-Buddhist frogs" competed for brains and came up with a strange way of life to deal with, so let us see it!
"Golden House Hidden Jiao" raises a baby - stomach yuxi toad
The frog in the game is alone, and he doesn't want to find a daughter-in-law (or husband) or even have a baby. This is simply a "great rebellion" in nature.
As amphibians, the tailless order, which is dominated by frogs, although not as well as mammals, cares for children in all aspects, but it is still conscientious in the incubation stage of children. Among them, the most "perverted" of the degree of love is the stomach breeding brook toad that has become extinct in the 1980s. (Note: In 2013, the University of New South Wales in Australia successfully bred live embryos of gastric Brook toad.) ）
The gastric brook toad is only found in the mountains of southeastern Queensland, Australia, and from its name we can get a rough idea of its habits:
"Creek" indicates that it prefers to live by wet, shallow rivers or streams.
"Stomach education" feels incredible at first glance, it doesn't matter, boldly say it: raise children in the stomach! It swallows the eggs into the abdomen and hatches in the stomach, and after hatching, the frogs live in the mother's mouth and abdomen for a week. This is really a realistic portrayal of "fear in the mouth".

However, the stomach toad inevitably has mistakes, for example, the female toad swallows X eggs, the last hatching will always be X-10 looks, it is possible to swallow eggs and stop secreting stomach acid There is a time difference, some of which are digested. It is also possible that the female toad's mouth is too small to swallow completely at one time, and there are eggs that leak out of the mouth.

Some people ask, if you can't melt in your mouth, then you will melt it in your stomach, right? Don't worry, during the hatching of the frog, the stomach of the gastric toad will temporarily stop secreting stomach acid to avoid the eggs from being corroded. Moreover, as the young frogs continue to grow, the stomach of the stomach breeding brook toad will be appropriately inflated to ensure that the young frogs have sufficient living space. What a touching love!
"Salt to pee cover" to take a sea bath - crab-eating frog
There is a wood to find, the frog in the game is a local tycoon, so big and comfortable house a person... A frog lives. In the cruel nature, many frogs have a humid freshwater environment is not bad, not to mention that some "magic" frogs are still soaking in salt water! What the? That's right...
It should be known that the lungs of amphibians are not yet very developed, unable to independently assume respiratory functions, so their slimy skin plays a role in assisting breathing, so its skin is extremely permeable, and it is impossible to jump in the salt water.
However, there is a kind of frog that lives in the subtropics "does not soak in ordinary water", often in the salty water at the intersection of sea and land, holding the roots of mangrove plants and sleeping, which is a rare sea and land frog (alias: crab-eating frog), which can survive in salty water with a salt content of 2.8%.

Don't be surprised, people have developed this ultra-high salt tolerance skill in the form of tadpoles in their infancy, and their sea and land frog tadpoles have more salt tolerance and can grow and develop in salt water with a salt content of 3.9%.
Well, crucially, wondering how their skin can stand salt, right? Experts from the Kunming Institute of Zoology of the Chinese Academy of Sciences have conducted special research on this and given the answer: the concentration of salt ions in the plasma of sea and land frogs and the concentration of urea in the kidneys are super high, which can achieve the balance of osmotic pressure inside and outside the body, and will not be killed.
"Bucket to Star Shift" brewed venom - arrow poison frog
Players have been saying that the frog in the game is indisputable from the world, pure and harmless, is a "Buddha" frog, then there must be a "demon" if there is a "Buddha", and the most fierce character in the frog world is the "magic" frog - poison dart frog.

First of all, we will analyze the name of the poison dart frog.
"Poison" is easy to understand, this animal uses venom as a weapon of attack and defense, which is not uncommon in amphibians, for example, many toads will use a little poison.
"Arrows" are not easy to understand. Is it an arrow on the body? Or is it secreting venom as fast as an arrow? No, this "arrow" word is to describe the poison of the arrow frog. Poison dart frogs are petite in size, rarely reaching 6 cm, but the toxicity is fierce, and the lethal amount of venom in half (LD50) is 0.00001 mg/kg ~0.0002 mg/kg.
Therefore, the inhabitants of the poison dart frog habitat, the Indian An people, have a unique idea, after catching the poison dart frog, the venom of the poison dart frog is smeared on the arrow of the bow and arrow, as a weapon to shoot the prey, the effect is quite sharp, which is the origin of the name of the poison dart frog.
Unexpectedly, such a powerful venom, but not like the poisonous snake, poisonous lizard is their own synthesis, the poison dart frog family frog toxins from the ants they eat, poisonous spiders and other foods, after eating these foods to absorb its toxins, synthetic frog toxins, in the artificial breeding environment, the poison dart frog is not poisonous. This can't help but remind the author of Murong Gusu's family's mastery- Dou to Star Shift!
"Exquisite and transparent" drying of the five viscera - transparent small tarsal frog
Flip open your phone, as long as the little frog is facing you, you can see its cute belly at a glance. However, in the Amazon rainforest areas of Ecuador and Peru, there is a transparent small tarsal frog with a mixed appearance of "cute" and "frightening".

To say it's cute, you have to look down at it and look at its back. This guy is small and delicate, only 20 millimeters long, about the size of a fingernail cap of a person, and the back is slightly transparent emerald green, looking like a mini pendant carved from jade.
To say it's terrifying, you have to look up at it and look at its belly. As we said just now, in addition to the pale green color, the back is also slightly transparent. But a look at the abdomen... This guy's abdomen is also too transparent, the peritoneum has no color at all, it is completely transparent, the white powdered intestines, the bright red liver and the beating heart are all in full view.

In this way, when it was on the emerald green leaves, the slightly emerald green back plus most of the other transparent parts, the predator could not detect that there was such a guy on the leaf, which was a superb camouflage technique.
When many people first see a transparent small tarsal frog, if they do not look at its transparent abdomen, they will treat it as a tree frog, after all, it is very similar to the tree frog in terms of posture and living environment. However, the transparent small tarsal frog does not belong to the tree frog family, but belongs to the star frog family, and the biggest difference is that when the tree frog observes the surrounding environment, the two eyes are staring at the side; while the transparent small tarsal frog is staring straight ahead when observing the surrounding things.
"Walking like a fly" to take the risk of nature - tree frog
I just mentioned the tree frog, so let's talk about the tree frog. Why? Remember what the frog in the game is in? Slowly and leisurely, comfortable and self-satisfied, such a "not in a hurry" personality also makes people mistakenly think that they have a turtle!
In fact, in the real natural world, in addition to toads, most frogs have not moved, a move is amazing, its jumping power is very strong, and the speed of movement is also amazing.
Why do we have toads except for toads, because the biggest difference in body structure between most toads and frogs is their front and back limbs. Toads have thicker forelimbs, so they are more suitable for slow crawling, while frogs have thick and powerful hind limbs, bounce lightly, and have a quick body. Among them, the most cattle are tree frogs.

Compared with ground-dwelling frogs, tree frogs differ in two main ways.
First, tree frogs generally have flatter bodies and more slender limbs than ground-dwelling frogs. From an aerodynamic point of view, such a structure is easier to reduce air resistance and increase flexibility in moving between trees.
Secondly, tree frogs generally have larger suction cups on their toes, and they also have "flat warts" with suction cup function on their chests. These two physical features help it securely hold its body to the trunk or even the leaves.
Relying on these two "magic weapons", tree frogs can walk like flying in the woods, spinning and jumping!
