Hagfish Slime Could Make Super-Strong Clothes

Having the ability to create a 20 liter cloud of slime and tie themselves in knots, hagfish have always been one of my favorite deep-sea denizens. Being a living slime dispenser has not won the species many fans however, with the notable exceptions of Mike Rowe and Dr. Egon Spengler. All that is about to change thanks to the work of a research team at Canada’s University of Guelph. They've found that hagfish slime might be used to make new plastics and even super-strong fabrics. From the article: "A research team at Canada’s University of Guelph managed to harvest the slime from the fish, dissolve it in liquid, and then reassemble its structure by spinning it like silk. It’s an important first step in being able to process the hagfish slime into a useable material, according to Atsuko Negishi, a research assistant and lead author on the paper in this week’s journal Biomacromolecules. 'We’re trying to understand how they make these threads and how we can learn from that to make protein-based fibers that have excellent mechanical properties,' Negishi said. 'The first step is can we harvest the threads. It turns out that is doable.'"

Yeah, that phrase "hasn't evolved in X years" has always bothered me. Of course they've evolved, their genes are subject to the same changes due to random mutation as everyone else's. It's just that the selection pressures on them have kept them largely the same (morphologically speaking) as far as we can tell from fossils.

You don't know that they haven't changed much. You can only tell that the general morphology (often just the skeleton) of a fossil find matches a modern animal. What does it tell you about the rest? Organs, biochemistry, innate behaviour?
