Just the word spider alone sends shivers down most people’s spines and with good reason too. The fact that they have eight legs and eyes is creepy enough but their diversity in species makes them dangerous because most of them are venomous. Spiders are also known for producing silk which humans use in medicine.Darwin’s Bark Spiders are known for producing a silk so strong that it is labelled as the toughest biological material. It’s silk is ten times tougher than kevlar which is used to make bulletproof vests. These non-poisonous spiders were first discovered in Madagascar and are found in tropical climates adjacent to bodies of water. They are capable of spinning webs that span over and across wide bodies of water in Madagascar in order to maximize their hunting of aquatic insects and alike. Since these spiders were discovered so recently, more research on them is needed in order to fully understand their extremely effective web biology.

Hi Tikweze!
ReplyDeleteIt's interesting to see that an insect that is feared across the globe can produce something that could be such an important resource for humans. Who knew that a spider's web could have the ability to repel a bullet.

Hi Brianna, I definitely agree with this point. I feel like it's easier to fear something we don't understand than to actually study and benefit from it
DeleteThe sheer strength of the bark spiders is incredible! I wonder what the molecular layout of such webs look like, and how closely woven the bonds at play really are? I also wonder with more research what applications such a strong biological material will be able to serve humans?

Hi Declan, we can only imagine what sort of technological advancements we can make with a biological material such as this spiders web. I can see a future where we all have indestructible clothes with this material!
DeleteAfter recently learning about kevlar in Organic Chemistry, I never knew that scientists have found a material that's stronger than this substance! Since spider web silk is so soft, and easily breakable, what would happen if someone walked through one of these spider webs? Would they be able to break it and walk through or would they get stuck? Something interesting to think about!

I believe if someone were to accidentaly walk through one of these webs it would feel like being tangled by some sticky dental floss
DeleteThe fact about kelvar was so interesting! It has me thinking about what it catches as prey if the spiders silk evolved to be that strong!
ReplyDeleteI really enjoyed your blog post! I think its super interesting that such a scary and unsettling animal can produce something so incredible. I wonder if scientists will look into using their silk in bullet proof vests.
ReplyDeleteThe fact that this spider's web is stronger than the material in bulletproof vest is crazy. It's scary but also very interesting. I've also heard about some spiders making webs so big a human can get caught in it. Scary creatures but also so cool. Love the post
