Research shows that   the clothing of the future may come from a primitive creature that lives at the bottom of the sea. 
This creature is   called a hagfish, an eel-like marine animal that has no jaws or spine. This   fish scavenges the ocean floor to feed   on dead sea creatures, especially whales.. Experts believe that hagfishes lived   as early as 330 million years ago. 
The hagfish protects   itself from predators by producing   slime from its body. This slime covers the mouth and gills of its predators   forcing them to back off or be unable to breathe.  
Scientists believe the   slime that a hagfish produces can be turned into clothing like tights,   breathable athletic wear or bullet proof vests.  
A hagfish has about a   hundred glands along the side of its body that produce milky and sticky slime.   This slime is composed of strong fiber that expands when mixed with seawater and   becomes silky when stretched and dried. 
Hagfish slime can be a   good alternative to man-made fibers like nylon or spandex, which come from a   non-renewable source. However, scientists still need to figure out how to   produce hagfish slime in large quantities. 
Today, no one has been   able to breed hagfish in captivity, making the formation of hagfish   farms highly unlikely. But, scientists are trying to artificially replicate   the proteins found in hagfish slime with a method similar to what was used to   imitate spider silk before.
