Hagfish, also known as slime eels, are eel-like fish equipped with a tongue having two pairs of rasps. They lack jaws, true eyes or a stomach.
Hagfish use their mouth to snag and then tear the flesh from the carcasses of their victims as they devour their prey from the inside out.
They have very slow metabolisms and after eating they may not need to feed again for up to seven months.
Hagfish live on areas of muddy sea bottom. The fish overwhelms any prospective predators by exuding massive amounts of sticky slime.
Despite these disgusting character traits, the skin of these creatures is often used to make expensive boots, bags, wallets and purses.
