You know, living on the ground is an adventure, and there are countless terrible, terrifying traps that are silently opening their mouths! As a result, countless animals moved to live underground, and although they sacrificed the light, they could be exchanged for safety. Unfortunately, this security is only relative, so, forced to make a living, they also fight a unique tunnel war underground, such as the money trapdoor spider.
Look, what's on the ground? An old coin, or a mini grinding disc? Better to touch it with your hand, heck, how can it move? Of course it will move! Because it is neither ancient money nor a millstone, but an authentic spider. Its scientific name is "Richter's Coiled Spider", people give it the nickname "Money Trapdoor Spider", its personality is docile and cute, and it does not love to fight like many of its kind. In its life, it is mainly defensive.
Its biggest feature is the belly, as if it has been suddenly truncated, and the backward side is not only flat, but also has various patterns, living like an ancient coin. If you touch it, you'll find it's still hard.
It's an excellent "belly"! After the money trapdoor spider, which is not good at walking and climbing, gave up the life of spitting silk and knotted nets, it relied on it to survive, and the money trapdoor spider dug a vertical, not wide and long tunnel on the ground, and then hid in it, using the "ancient money" as a living cover to block the opening of the hole. This "ancient money" is as strong as a shield, and the Richter's coiled spider can be completely safe when it is hidden.
What if you are hungry, when the insect passes by, accidentally step on the "ancient money", it only needs to collect the stomach, the insect will fall into the tunnel, haha, the meal to the mouth!
