The spiders we often see are either cute...
Or else it's fierce...
And today this one is really ugly and ugly.
How ugly: black body, stout eight-legged, big "ass", scary "fangs", how to see is not to take the cute route, look up and even harm piapia ~
So why is it cute?
See "Farts"
"Fart" has a logo on it!
Woohoo! Is such a magical spider SEI?
Amputatifers, belonging to the genus Cyclocosmia spp. of the family Cockroaches, ann, know that you don't recognize words, come and pronounce the cockroach [dié dāng] together, pronounce the cockroach [dié dāng] again, pronounce it again...
Promise me, you must remember, okay?
Amputated spiders, image it. Their abdomen seems to have been cut off by a knife, and there is a strange pattern on the cross-section, and the shape of the pattern is like a coin or seal, so it is also called a "seal" spider.
Seal spiders are extremely rare, and their genus, the genus Of the Pangetaceae, is a small genus of spiders, found in a total of 7 species around the world, distributed in the United States, China and Southeast Asia. Tell you the location, and by the way offer different kinds of seal patterns:
The good news is that there are 7 species in the world, and China accounts for 3 species, namely: Cyclocosmia ricketti, Cyclocosmia latusicosta, and Cyclocosmia lannaensis.
It's a good time and place,
First find the seal in China,
Stay until the collection of 7 models,
You can summon the dragon.~
However, it is not so easy to collect seals, they are rare in number, their whereabouts are hidden, and they encounter only a few times a year (wild).
Of course, there are also great possibilities, and I don't know when I encounter them:
They cave underground and rarely go out, but sometimes they show a "fart" at the mouth of the cave.
Guess what it does to expose a "fart"?
。。。
predation?
They will block the "fart" at the mouth of the hole, so that the cross-section of the "fart" is level with the ground, and then wait for the worms, small spiders, and small prey to come to the door to "pat the fart", as long as there is prey passing, immediately contract the abdomen to let the prey fall into the hole or immediately turn around and drag the prey into the hole, and then eat it slowly, while warning them fiercely: the spider's "fart" cannot be touched!
Is this true?
No, after observation, it was found that the seal spider mainly takes the form of ambush, lurking at the entrance of the cave at night, stretching out two pairs of stepping feet (there are many sensory hairs on the foot, you can feel the vibration of the ground), when the prey passes, it will rush out of the cave entrance, using the tentacles and foot to give the prey a loving hug.
So what is the "seal fart" used for?
Block the door, forbidden to enter!
Since it is not used for predation, it is for defense: whenever they feel that a predator (bees and scorpions) is approaching, they will immediately drill into the hole, turn their bodies upside down, and plug the entrance with "farts", so that the predators will have nothing to do, and their abdomen is strongly leathery, and the end is thickened, which can block the sting needles of the bees.
Just like the big-headed ant of science popularization before the editor - turtle ant,
Its large head is also used to block the door defense.
From this point of view, the best defensive skills are:
When the enemy soldiers approached the city, they constantly provoked and shouted
"Die!"
And I can answer proudly
"You have the ability to come in!"
