by Also known as slime eels, hagfish are primitive fishes.
They have five hearts, no jaws, no true eyes and no stomach.
They have poor vision but a very good sense of smell and touch.
Hagfish live in burrows on the seafloor and locate their food by smelling and feeling as they swim.
They prey on small invertebrates living in the mud; they also scavenge dead and dying fish.
Hagfish are noted for their unusual way of feeding — they slither into dead or dying fishes and eat them from the inside out, using their "rasping tongue" to carry food into their funnel-shaped mouths.
