Do spiders have a memory? Does the little jumping spider have a memory?

The spider is surrounded by a chitinous exoskeleton, and the body is clearly divided into cephalothorax and abdomen, which are often connected by a thin stalk that becomes the first abdominal segment of the abdomen, without a caudal segment or tail whip. The spider has no compound eyes, and the cephalothorax has 6 pairs of appendages.

The first and second pairs belong to the head appendages, of which the first pair is chelicera, most of which are chelicera, most of the base is chelicera, the tip of the tip is chelicera, the teeth are tubular, and the venom secreted by the chelicera or cephalothorax is derived from this. The second pair of appendages are called foot whiskers, which are shaped like feet, but only have 6 segments, and the basal segment near the mouth forms a jaw-like protrusion, which can help feeding, and there is no major change in the female spider's terminal segments, while the male spider's foot whiskers are specialized as reproductive auxiliary organs, with sperm storage and sperm transfer structure, called tentacles. The third to sixth pairs of appendages are footed, consisting of 7 segments, with claws at the end and a tuft of bristles under the claws, so they are suitable for crawling on smooth objects.

Spiders have memory, and there is growing evidence that insects and spiders can form and use detailed memories, similar to humans, but using very different mechanisms.

Humans use the "positional cells" in the hippocampus to orient themselves, which arthropods lack. However, their brain regions have evolved to perform the same function. The central nervous system of humans contains the spinal cord and kilograms of brain.

In contrast, spiders have two groups of neurons called ganglia: one above the esophagus and one below the esophageal group.

The key input to the spider's brain comes from thousands of sensors on the spider's exoskeleton, called slit receptors. Each one looks like a tiny crack that deforms as vibrations sweep across the spider's body. Spiders are very good at perceiving vibrations, and through vibrations, they can tell if Delicacy has fallen into the web, or if someone is poking around with a stick.

So spiders also have complex memories, complex thinking.

Habits of spiders.

1. Eating habits. Spiders feed on insects, other spiders, myriapods, and some spiders also feed on small animals. Jumping spiders have good eyesight and can dive within 30 centimeters to catch their prey and pounce on them.

Crab spiders wait for their prey on flowers that are similar to their body color. Spiders burrowing in the earth build burrows lined with silk, and the entrance of the burrow has a trap that opens at night to prey on insects that pass through the hole.

funnel spiders weave funnel webs, and insects fall into the nets to cause vibration; The spider itself dwells in a filament tube with a narrow end that leads into a plant or a crevice in a rock.

2. Lifestyle.

The lifestyle of spiders can be divided into two main categories. That is, the nomadic type and the sedentary type. Safari type spiders, spiders that hunt everywhere, hunt, have no fixed residence, do not build webs, do not burrow, and do not build nests. There are scaly arachnidae, ursoaradae and most tarantulas.

Sedentary: some build nets, some dig holes, and some build nests as fixed dwellings. Such as wall money, stone-like spiders, etc. Spiders seem to be polite, and those who live independently keep a certain distance from each other and do not invade each other.

Little jumping spiders have memories.

To put it simply, small jumping spiders have the ability to remember, because they rely on hunting and prey, rather than weaving webs to guard the prey, so this requires the jumping spider to be able to distinguish their prey species, after experience, jumping spiders can make different strategies to hunt according to the different types of prey, and can also be adjusted at any time.

Jumping spiders rely on well-developed vision to make close observations of their prey after seeing it from a distance, including constantly adjusting angles and distances at a distance, stalking between bunkers (if any), and sometimes even going farther away to observe their prey.

There are even some species of jumping spiders that pretend to be their prey, running to the web-forming spider's web to shake their legs, attracting the web-forming spider to come and feed (in fact, to die), and then the jumping spider will use its agility and agility to hunt the web-forming spider.

The habits of jumping spiders

The jumping spider lifestyle is generally to catch insects by jumping. In fact, they will also spin silk, some varieties will also make nets, belonging to the rabbit hunters, they spit the silk is to play the role of "safety rope", especially when crawling in a vertical place, will use silk to fix the body, to prevent slipping.

When it comes to courtship, jumping spiders will come out of their nests, find a wide plant, take a "sun bath" on the top of the flowers and plants, and rely on ultraviolet light to make themselves more "**".
