Covering
yourself in hagfish slime may not sound like the smartest thing to do…
But researchers from Canada’s University of Guelph have discovered that
it’s actually not such a bad idea.
The hagfish (which isn’t
really a fish in the conventional sense) is a living fossil. It has
undergone little to no evolution in the past 300 million years. It has
an interesting and effective defence mechanism t
hat
can repel even sharks. When threatened, it releases large quantities of
protein. This protein, when released into the water, forms threads that
turn the immediate environment of the hagfish thick and gooey. The
slime, which “smells like dirty sea water”, according to one of the
researchers, deters predators from attacking the hagfish.
The
researchers have found that the protein threads can be isolated from the
slime (via the removal of water and mucous). The protein threads
themselves are categorized as ‘intermediate filaments’. Each thread is
100 times smaller than a single human hair. These fine threads can be
woven to create fabric that’s as strong as nylon or plastic. With more
research, these fabrics can even be used to make clothes! Hagfish
produce large amounts of slime in mere seconds. The mere efficiency of
this process grants it an advantage over harvesting silk from silkworms.
Furthermore, the material is much more sustainable than artificial
fibers like nylon and polyester. In the words of the head researcher,
Atsuko Negishi, “This work is just the beginning of our efforts to apply
what we have learned from animals like hagfishes to the challenge of
making high-performance materials from sustainable protein feedstocks.”
The next challenge would be to make the process feasible on an
industrial scale. It’s unlikely that slime will be directly harvested
from the hagfish in large amounts. Alternatively, the slime-making genes
might be transplanted into bacteria, which can be cultured to provide
the slime on a much larger and more feasible scale.
