Atsuko Negishi (left) holds up a an Atlantic hagfish (Myxine glutinosa) and the slime it produces when provoked or stressed. Douglas Fudge (right) and his team are investigating the properties of fibers in the goo. Andra Zommers/Univ. of Guelph Step aside spiders. Threads made by another creepy-crawly — the eel-like hagfish — may lead to superior new fibers for parachutes, packaging and perhaps even clothing. A new study that examines the mechanical properties of threads made from hagfishes’ slimy mucus finds the fibers are both strong and stretchy, and may serve as a model for creating superior new materials. “The tensile properties approach those of spider silk, and that’s very exciting,” says biomaterials specialist Douglas Fudge of the University of Guelph in Canada.

-0.28583“There’s very little that’s been known about hagfish. People don’t like them and think they are gross,” says research scientist Vincent Zintzen of the National Museum of New Zealand in Wellington. “The idea of looking at their slime is very interesting. It’s totally different from anything that we’ve seen in the natural world.”

Key:

  • Aggregate Sentiment is meant to be an indicator of an individual's overall sentiment.
  • The Mean is meant to be an indicator of an individual's average comment sentiment.
  • The Standard Deviation, when there are enough quotes, will indicate an individual's consistency of sentiment (i.e. a Standard Deviation of 0 would mean they were very consistent in their sentiment and 1 would mean they were very inconsistent).

Note that quote stats are likely to be meaningless beyond the aggregate score due to the tiny sample size. However, they are always provided just in case you find something useful there.
