Spiders are a common animal in life. They are found in almost all parts of the world. Most of them live in the wild by weaving webs on trees to catch passing insects for a living. Others do not weave webs. They often walk on the ground and rely on safari to survive, and a small number of them live with humans and like to weave nets on the corners of human roofs to prey on mosquitoes and flies. There are 3,821 genera and 42,055 known species of spiders in the world. It is currently the largest spider in the world, the Amazonian giant tarantula.
The Amazon jungle is the largest forest in the world, with dense forests and a wide variety of animals and plants. It is known as the "Kingdom of Animals and Plants in the World". This place is home to one of the largest spiders in the world, the giant tarantula. The Amazon giant bird-eating spider is recognized as the largest spider in the Arachnoid class. Its body length from head to toe can reach up to 30cm in length and its weight can reach 230 grams. It is a well-deserved "spider king".
Classification of tarantulas in nature
There are many kinds of tarantulas all over the world. As of 2013, they were discovered by humans and divided into 13 subfamilies. There are 124 genera and 935 species of tarantulas under the subfamily. The Amazon rainforest in South America is the hometown of tarantulas, and there are the most species of tarantulas. The most famous one in China is the tiger-pattern tarantula, which is a new species of tarantula discovered in Guangxi, my country in recent years, because The poison is the strongest among all tarantulas and is known to be the most poisonous of all tarantulas. It is said that it can poison a cow.
There are three types of tarantulas: tree-dwelling tarantulas, ground-dwelling tarantulas (including burrowing tarantulas)
1. Tree-breathing tarantulas, as the name suggests, are tarantulas that live on trees. They usually build webs on trees to build nests and prey on animals that stay on trees. Their nests are generally in the holes of tree trunks. Into a round pipe, and into a "U" shape.
2. Ground-dwelling tarantulas (burrowing tarantulas)
Ground-dwelling tarantulas and cave-dwelling tarantulas can be combined into one category, because the difference between them is that one type digs holes to make their own nests, while the other type does not make nests and only finds some mammals burrows, such as the burrows of mice or snakes. The Amazon giant tarantula is a typical ground-dwelling tarantula.
Most ground-dwelling tarantulas are burrowing, and they only hunt near their nests, generally not too far away. The female tarantula will live in its own cave for the rest of its life, and will change its nest all the time, but the male tarantula will abandon its nest to find a mate during the mating season because it is looking for the opposite sex to reproduce offspring. They leave after mating.
The unique hunting skills of giant tarantulas
The Amazon giant tarantula has 8 eyes on its head, and is known as the "eight-eyed spider king". Although there are many eyes, it is useless. Its eyesight is very poor, equivalent to a high degree of myopia. Couldn't find it next to it. It has a special ability that enables it to quickly spot prey.
The giant tarantula, like other types of bird-catching spiders, has the ability to spin silk and weave webs. The only difference is that other types of spiders hang their webs in the air to catch their prey, while they lay their webs in caves. Inside and outside the hole, it is more like a thin white carpet, and then it hides in the middle of the carpet in the hole. Each spider silk on the carpet is like a sensor. Silk, spiders hiding in the hole quickly know that there is a prey approaching, and make corresponding measures. Therefore, the giant tarantula is one of nature's most ingenious hunters.
Of course, in addition to hunting, this silk can also help giant spiders resist the dampness in the cave and stabilize their home.
For giant tarantulas, this kind of web is only equivalent to a braid full of bells, acting as an alarm, not a tool to trap prey. For hunting, they are more adept at using traditional methods of close combat, that is, hunting with fangs and bristles on their bodies.
They have long fangs, generally 5 mm long, which are very hard and can easily bite into the body of their prey. Although the venom of this spider is relatively weak, the amount of venom secreted each time is still more than other spiders, which is more than enough to deal with some insects and small vertebrates, enough to cause the prey to stun or paralyze.
The giant tarantula's most powerful weapon in hunting is not its long fangs, but the countless bristles on its body. If you magnify the bristles a few hundred times and observe, you will find that the bristles under the abdomen are like small fish hooks with barbs on them.
When a tarantula attacks its prey, the bristles on its abdomen are usually more effective than the fangs. When they hunt, they quickly rub their back feet against their abdomens, causing a large number of bristles to fall on their prey, which can be fatal to small rodents because of the number of bristles released at one time. There are hundreds or thousands of them, so the more poisonous ones can quickly kill the prey.
The Amazon giant tarantula can be said to have no competitors in the insect world. Even large birds are afraid of this animal.
There are many kinds of parasitic wasps, some of which are larger and more aggressive and can knock down big guys like giant tarantulas. Although bird-eating spiders don't immediately recognize them when they see them, they will use their forelimbs and poisonous stingers to defend themselves, but these parasitic wasps can easily avoid its attacks. On the contrary, even spiders' self-defense actions are in their eyes. A fatal flaw.
Sometimes bird-eating spiders can't beat the parasitic wasps, and in order to escape, they will immediately hide in the depths of the nest, and use their own nets to seal the holes to prevent the parasitic wasps from attacking. But some powerful parasitic wasps can still find them, and some can even burrow into the dirt.
They dug their burrows quietly and paralyzed the spiders with poisonous needles when they weren't paying attention, causing them to become unconscious like vegetative people. Then lay eggs in its body. After hatching, the larvae feed on the spider's guts, starting with secondary guts until they metamorphose a few times into adults. This behavior of parasitoid adults and nymphs can effectively ensure the freshness of food. Common parasitic wasps in the Amazon include the horned wasp, the wasp, the golden wasp, and the wasp.
Many people now like to keep this Amazon giant tarantula as their pet, although they are generally harmless to humans in nature, and like most other tarantulas, they do not actively attack humans. But if humans accidentally anger the aggressive spider when trying to catch it or while raising it, it won't be polite.
Which spider is bigger, a Goliath birdeater or a tarantula?
It's said that Goliath birdeater is bigger than tarantula. the goliath bird-eater is the world's biggest spider, which leg span nearly a foot wide. And the tarantula spans nearly a foot and weighs as much as a baseball.
It will attack you with its own fangs. If it is stabbed by its bristles, although this poison is relatively mild to humans, it will not cause life-threatening, but a small amount of toxin will make your skin tingling. It was extremely itchy and painful. If it gets in the eye, it is basically difficult to pull out, which can seriously lead to blindness. Therefore, I advise people who love to play with this kind of spider to be careful!
