Do you have joints to spider?
The spider's legs have seven joints (photo: Eky.edu). Humans have only one major joint per limb (knee, elbow, etc.), while spiders have seven joints on each leg. The result of having a multi-joint exoskeleton is that the spider does not have bone support for the flexor and extensor flotillas. 16th. 2014
Is the spider flexible?
It is flexible enough to move, but it cannot be expanded like human bones and tissues. That is, you cannot grow. To increase its size, the spider must form a new, larger cuticle exoskeleton and shed the old one (this is called molting).
Are the spider's legs flexible?
Each leg has 7 segments, so you can use 8 legs to adjust 56 individual body parts. Spiders have an exoskeleton, an exoskeleton made of chitin and protein, and no internal bone. Inside the exoskeleton, there are muscles that bend the legs and pull them inward.
