Hagfish are primitive, eel-like fish that are nearly blind and lack jaws or true vertebrae, but they have the unnerving capability of producing copious amounts of slime when disturbed...
... Unlike the mucous produced by the membranes of humans and other animals, which become more rigid, viscous gels at and below ambient body temperatures, the researchers (Gavin Braithwaite, 617-629-4400, gavin@campoly.com; Douglas Fudge, dfudge@interchange.ubc.ca) found that Hagfish slime is much less elastic, even at high concentrations, than its human counterpart.
In addition, over the ranges of temperatures encountered by the hagfish, the gel strength is relatively temperature independent. The insensitivity to temperature perhaps ensures that slime is an effective defense in a variety of conditions. In addition, artificial materials that mimic Hagfish slime chemistry might make good space-filling gels.
Hagfish slime is unlike other slimy secretions in that it is reinforced with very fine fibres. Our data show that these fibres lend tensile strength and toughness to the slime. Subsequent research will investigate the mechanical properties of the mucus component of the slime, as well as the properties of naturally-produced slime cocoons.

I guess that could lead to questions such as "Would you like your groceries in paper or hagfish slime?" It would be interesting to note the people's reactions.
Hagfish slime contains a protein called "thread," which can be used to create a strong, flexible material. This material is being studied as a potential replacement for plastic in various products such as packaging materials, clothing, and even medical devices.
Yes, hagfish slime is considered to be an environmentally friendly option compared to plastic. It is biodegradable and does not release harmful chemicals into the environment. Additionally, hagfish are a sustainable source as they can be farmed rather than harvested from the wild.
Hagfish slime is incredibly strong and can be stretched up to 10 times its original length without breaking. This makes it comparable to synthetic materials such as nylon and polyester. However, more research is needed to fully understand its strength and durability in different applications.
One limitation is the production process. Currently, it is difficult and costly to extract the thread protein from hagfish slime. Additionally, there may be concerns about the potential for allergic reactions in individuals who come into contact with the material.
Aside from being environmentally friendly, hagfish slime has the potential to be a versatile and multi-functional material. It can be used for various applications such as adhesives, coatings, and even as a food source for fish. It also has the potential to reduce our reliance on non-renewable resources used in the production of plastics.
