In this blog post, we will be discussing the spiders and their death in great detail and start off by answering the question “How Do Spiders Die Naturally?”. Spiders are really fascinating and interesting creatures. You might hate them or they may disgust you but you cannot refuse to believe how impressive these little monsters are!
Spiders are the most widely inhabited anthropods which mean they are not in anyway insects. Yes, you heard that right spiders are not insects. So why are you reading this blogpost under the name “Insect101” because spiders are commonly perceived as insects and leaving behind our favorite and coolest crawling creep would be such a loss! Moving back the the main crux of this topic let’s start talking about spiders death by answering the question “How Do Spiders Die Naturally?”
Spiders usually die because there body becomes weak and not powerful enough to support itself anymore, this happens many times with females after giving birth and males after mating. This also might occur due to the harsh weather condition in which a spider is, a mere lack of food or due to catching a deadly disease
The dead bodies of the dead spiders are often avoided by other spiders who go on to mind their business, unlike ants who take their fellow dead mates the outskirt dumpsters of their colonies, if you want to know more about how ants deal with their dead, we have a great article written on it, you can give that a look “here“
Death Of Spiders By Diseases
It is very common for spiders to catch bactarial infections this often leads to them becoming very weak and unable to get their prey, but usually they don’t die because of this disease because before that can happen they either die of starvation or are hunted by other living creatures looking for a snack.
Do Spiders Have Heart Attacks?
Yes, but a spider having a heart attack is very rare, heart attack happens when the blood being pumped to the heart is blocked due to a blocockage of fats. But this is something that is very unlikely to happen in ants, but as they do possess hearts near their abdomen, it wouldn’t be wrong to admit that it does take place from time to time
Do Dead Spiders Decompose?
Yes, ofcourse they do, being organic creatures themselves, dead spiders do decompose after they are dead. though the speed of decomposotion of the dead body of a spider really does depend on the sorrounding where the spider was when it died
Do Spiders Curl Up When They Die?
Yes most spiders legs do curl up after rthey are dead, spiders do curl up after they are dead, this is a symptom of an ailing spider’s decreased coordination and failing nervous system.
Science Behind Curling Legs Of Dying Spider.
In the legs of spiders, the femur-patella joint and the tibia-metatarsus joint extend by hydraulic pressure only. Spiders do not have muscles for extending the legs at these joints. Spiders control the hemolymph (their blood) pressure in the legs to extend them and walk.
However, there are muscles for contracting these joints. So when hemolymph pressure drops, there is only a force of contraction and no force of extension. The legs therefore contract and curl up.
Other Possible Reasons Behind This Phenomenon.
Is it Gravity?
The explanation has to do with gravity. The heavier mass of the dorsal side (back) of the spider’s body falls hits the pavement, leaving it upside down.
Their body build might also be the reason behind this, as spiders have their center of gravity resting high up on their backs and so when they lose control over their nervous system they topple upside down due to center of weight.
Or blood pressure?
Another possible explanation involves the flow of blood—or lack thereof—in a dying spider’s body. As the spider dies, blood flow to its legs ceases, causing them to contract. Again, as the critter’s legs fold up beneath its considerably heavier body and the laws of physics take over.
The most common explanation for why spiders die on their backs is something called the “position of flexion.” When a spider is dead or dying, it cannot maintain tension in its leg muscles and naturally falls into a state of relaxation. The explanation goes that in this relaxed state, the spider’s legs curl or fold up, causing it to topple over and land on its back before it expires.
Can spiders survive Big Falls?
Yes, spiders can indeed survive falls, but their survival rate does truly also depends on the type of species they belong to. Moreover, their survival oes also depend on the overall height they fall from as one might have guessed
Can a Spider die from falling?
Yes, though this is very rare, but it is possible for a spider to die from falling. however, some of the species of spiders are not evoloved in a way to handle as elegantly
Moreover, smaller spiders also often use their legs to slow down their descent in case of falling, this means that the chances of a safe landing by a smaller spider are more then that of alarge spider. S
the saying, “The bigger they are the harder they fall,” is, quite accurate for spiders. Larger spiders can also find themselves quite badly injured due to a large fall or in some cases even dead, if you throw a large spider from the 3rd story, there is a very high probability of it getting severely hurt or even dead
Pretty much any spider will shake-off falling from your ceiling to the carpet or even a hardwood floor, but larger spiders will find themselves quite badly injured or killed from a longer fall (say from a third-story window to the ground). Then smaller spiders will basically be fine and might very well be thankful for an opportunity to float among the air if you try to toss them.
