English: "Fabrication of the necrobotic gripper. a) A spider is euthanized by application of cold temperature. The patellofemoral joint of the spider was visualized with a scanning electron microscope (SEM) to show the articular membrane at the joint with the stroller sun shade geometry. b) A 25-gauge hypodermic needle is inserted into the prosoma of the spider and sealed with glue. The SEM image shows the glue forming an airtight seal around the needle and the cuticle (or exoskeleton). We performed the same procedure with blue-dyed glue on a similar needle to illustrate the self-sealing mechanism. c) After the glue has cured, a syringe (or any suitable pressure source) is connected to the needle, completing the fabrication of the necrobotic gripper."
