Researchers have discovered that the defensive slime exuded by hagfish may be a source of high-performance protein fibers that could replace petrochemical-based polymers, such as nylon and plastic fibers, and fabrics woven from them. (Source: Wikimedia Commons/Peter Southwood)
This could indeed be a valuable discovery, although it appears that quite a bit of process development will be needed. Possibly the best part may be the independence from petro-chemical feedstock requirements, although we were not told just what the feedstock does come from.
There should be quite a range of applications for the final product, though.
As for the name, why not call then "armor-fish", which has a much better ring to it.
