If a spider loses one or more of its legs it will usually regrow them in the next moult (the next time they shed their exoskeleton).
Not only does the shedding allow for growth, but it will allow for regeneration too. If a spider is unfortunate enough to lose a leg, then provided it still has at least one more moult left in its life cycle it's able to grow a new leg. In most species the new leg is thinner and shorter than the original leg.

Yet there does appear to be a limit to how many legs a spider can lose. In the wild, the team found few spiders missing more than two legs.
Arthropods ( a group including spiders , insects, crustaceans etc) don't feel pain the way vertebrates do. They just react to external stimuli. Even if they could feel pain, dropping them isn't really going to hurt them anyway.
Abstract. Leg loss is a common phenomenon in spiders, and according to the species 5% to 40% of the adults can present at least one missing leg. There is no possibility of regeneration after adult moult and the animal must manage with its missing appendages until its death.
To a spider, losing a leg isn't a very big deal. Heck, some even voluntarily castrate themselves. Overall, there's a slight lag in development time. Being short a leg or two (or six) is going to slow you down a bit, which makes prey harder to catch.
Sometimes when we get too close or disturb them, they treat us like they would treat any predator. Many spiders have threat displays intended to scare off predators, such as rearing up or lunging. Biting in self-defence is another strategy that spiders can use when they are afraid for their lives.
They don't feel 'pain,' but may feel irritation and probably can sense if they are damaged.
Like most animals, spiders have circadian rhythms. These internal clocks tell the spider when to rest. Just like other animals, some spiders rest at night while others rest during the day.
Do huntsman spiders intentionally chase you? No. If you try to catch a huntsman and it runs towards you, it isn't attacking. It is trying to get to a safe place, away from the giant human thing looming over it.
Huntsman spiders are a non-aggressive group of spiders. They are very timid and will try to avoid and when encountered can move at lighting-fast speed to escape human contact. However, a large individual can give a painful bite. Beware in summer when the female Huntsman Spider is guarding her egg sacs or young.
Huntsman spiders have an unfortunate reputation. One is their name. The other is a tendency to take up residency in your home or your car and scare the bejesus out of you. But they are harmless to humans and very useful in controlling mosquito and cockroach numbers.
They are generally very docile and don't bite easily, with the exception of the females on the nest, who will bite if the nest is disturbed. The bite is initially painful but becomes itchy and all symptoms fade in a couple of hours. They feed on insects and small vertebrates around the house or garden.

This docile spider feeds on insects and small vertebrates. Their bites cause a mild pain similar to a bee sting and may be itchy for a while. It's not needed to visit a doctor.
Spiders do have feelings, but unlike a dog or a cat, they won't bond with you. In fact, they likely won't even recognize you. They simply aren't hardwired to be companions to humans and should never be bought at pet stores, online, or anywhere else.
The researchers mated 68 virgin P. globosus females with two males. They found that the number of squeezes the males made were associated with the number of times the females cried out during sex. Stridulations became more frequent if males failed to loosen a squeeze in response to a previous plea.
Are spiders afraid of humans? Yes. This is why spiders are most commonly encountered in seldom used areas such as garages, attics, basements, closets, or guest rooms. Spiders are antisocial and try their best to avoid human contact.
While the theory is unproven, it is likely that spiders can detect human fear. However, there are only few studies about this topic and it is not yet known for certain. Different animals have sensory organs that are able to identify different stimuli.
Over 21 days, the itty bitty spiders that were constantly exposed to hints of a predator stopped eating, lost weight and, finally, gave up the ghost. Persons was surprised to find that spiders can be scared to death "even when the predator isn't present!"
They are essential to our ecosystem; they are our friends, not our enemies so we need to find a way to learn to live alongside them. They really are more scared of you than you are of them and would much rather run away. Even the big spiders such as tarantulas don't want to hurt you.
These eight-legged creatures hate the smell of citrus fruits such as lemons and oranges. They also don't like peppermint oils, tea tree oils, eucalyptus, and vinegar. Using any of these around your home will keep spiders away.
Answer: Spiders are arachnids with eight legs, as do all arachnids. Spiders differ from insects in that they have only six legs.
Snails, spiders and octopi have something in common- they all have blue blood! We're not talking in the sense of royalty, these creatures literally have blue blood. So why is their blood blue and ours red? One of the purposes of blood is to carry oxygen around the body.
However, most scientists agree that spiders and tarantulas aren't capable of having feelings in the way humans think of them. Tarantulas might feel something, but it's more basic and very different from what complex animals like mammals feel.
