"Indeed, it’s one of the softest materials ever measured. “Jell-O is between 10,000 and 100,000 times stiffer than hagfish slime,” says Randy Ewoldt from the University of Illinois at Urbana-Champaign, who had to invent new methods for assessing the substance’s properties after conventional instruments failed to cope with its nature. “When you see it in a bucket, it almost still looks like water. Only when you stick your hand in and pick it up do you find that it’s a coherent thing.”"But it turns out that hagfish themselves are pretty weird, if you read the whole article.
Let's just say that lying in corpses, absorbing nutrients through your skin (because it's more efficient at doing so than your gut) is no way to go through life, son. But it works for the hagfish, apparently.
