adhesive tape-like suture

This is a caddisfly larva, or a rock roller as it is also known. It's a strange little bug that while in larva state, lives underwater and creates its own "shell" by spinning a sticky silk that collects sand grains. Scientists are using this as an inspiration for a biomimetic solution in surgery, hoping to create a synthetic version that can be used as an adhesive tape-like suture. http://www.treehugger.com/files/2010/03/underwater-bugs-in-medicine-caddisfly-silk-inspires-scotch-tape-solution-for-surgeries.php
