While trapping a spider to take it outside one of these people accidentally crushed its leg. What the spider does next is amazing!
Right after having its leg squished this spider went to work making a cast! How interesting is that? This spider used its two pedipalps, appendages on the front of its body in a way similar to hands. This is truly amazing. Spiders make webs all the time so it should come to no surprise that they can make other things as well. To see this spectacular occurrence watch the video below.
