Animalsphotography ### spider is terrible
Good evening all, tonight I am back with animalsphotography spider, below are some small spider images that I took with xiomi redmi 4a smartphone, I hope you like them....
Many people consider this creature to be a kind of insect, even though the fact is that spiders do not belong to insects. even though they are in the same phylum that is arthropod (segmented animal) but the spider is different from the insect.
the spider has a pair of large-jawed jaws (chelcera) and a mouth aid called a pedipalpus. The spider does not have teeth to chew, as the spider's mouth functions as a suction device to suck the prey's body fluids. Not all spiders make nets to catch prey, but all are capable of producing silk threads. Silk thread is produced through the spineret gland located on the back of the abdomen.
let's imagine ... a fly is flying here and there, he doesn't realize that in front of him there is a spider web. What happened..? what happens is that the fly is stuck and stuck in the net. how can a thin-looking net stop a fly flying at a high speed ??
Spider threads consist of long bonds of protein molecules. This thread has a high elasticity of up to 40%. the elastic properties come from small liquid granules on the thread. each grain contains a spare thread, which if there is a prey caught in the thread in the grain will automatically elongate so that the net will not break.
They are out there using spider yarn as a model when making materials called kevlar, which is a material used in making bulletproof jackets. the kevlar material is five times stronger than iron.
however, spider yarn that is thinner than hair and lighter than cotton turns out to be 10 times more powerful than kevlar material, and 5 times more powerful than steel fibers of the same thickness. whereas we know that steel is the most powerful material that humans use as building construction.
