I think a list of biogenic (i.e: produced by life processes) materials with remarkable properties would make everyone's lives on the site easier.
Of course, super is pretty objective, so we're focusing on the following categories:
Stiffness: Usually it shouldn't stand by itself, but it's is an important secondary characteristic of materials. For instance, while spider silk is very strong, it's also very stretchy, limiting its use. Wait, sorry, that's the elastic modulus. Stiffness comes into play for structures made out of a certain material.
Tensile, Shear and Compressive strengths: These are pretty self-explanatory. In a nutshell, tensile strength is important when stretching, compressive when crushing, shear when you're trying to cut it with a scissor.
There are, of course, many more. For instance, shock loading which is important for bullet resistance, but that's a can of worms for another day.
Let's make a list of biogenic super materials that excel in one of the aforementioned categories.
