One startup company for example, Benthic Labs, turned to the Hagfish with the ultimate goal of developing a biodegradable polymer made out of components of the slime itself. Slime. Hagfish slime can be revolting but it is also serious business: it is versatile and potentially sustainable. To produce these materials, Benthic Labs intend on inserting hagfish DNA for the filament proteins into bacteria, transforming them into filament-producing factories. Wikimedia Commons. However, hagfish slime isn’t as strong as it is purely because of the filament proteins- lots of other factors are also involved. The slime is released from slime glands, arranged in two ventrolateral rows along the length of th Hagfish tie themselves into a knot which they travel down from head to tail to remove the slime from their bodies, and they use a reverse knot, from tail to head, to anchor themselves to help in tearing flesh from their prey. Hagfish slime has three main components: seawater, mucins and slime threads. Vocabulary: For each of the underlined words, write a short definition based on the context of the reading.

The Fudge lab have successfully spun their own threads from hagfish slime, bringing us one step closer to being able to mass-produce slime materials for commercial and industrial use. Ron Newsome Once the skeins are introduced into seawater, the material expands approximately 10,000 times in a matter of milliseconds. Researchers hope to use the protein threads to make a fabric. Hagfish slime is composed of two interacting components, slime thread skeins and mucin vesicles , which are both released from glands along the ventrolateral length of the animal (Blackstad, 1963). One possibility is that the slime acts as a defence against gill-breathing predators, whose gills may become entangled with the slime's mixture of mucins and fibrous threads during an attack.
