In captivity, hagfish are observed to use the overhand-knot behavior in reverse (tail-to-head) to assist them in gaining mechanical advantage to pull out chunks of flesh from carrion fish or cetaceans, eventually making an opening to permit entry to the interior of the body cavity of larger carcasses.
The Pacific hagfish (Eptatretus stoutii) is a species of hagfish. It lives in the mesopelagic to abyssal Pacific Ocean, near the ocean floor. It is a jawless fish and has a body plan that resembles early Paleozoic fishes. They can excrete copious amounts of slime in self-defense.
Hagfish have very flexible bodies which allow them to manipulate themselves into knots. The knots created by the hagfish remove mucus from the body, allow them to escape tight spaces, pull potential prey from burrows, and because they have no opposable jaws it helps create leverage while they eat.

Eptatretus deani, the black hagfish, is a species of hagfish. Common to other species of hagfish, their unusual feeding habits and slime -producing capabilities have led members of the scientific and popular media to dub the hagfish as the most "disgusting" of all sea creatures.
Both the body and face of the fish are pinkish-orange in color. The most defining characteristic of this species is the elongated tubular nostril, something that has only been described in two other species, E. eos and E. lakeside. Both of these species also share the pinkish color of the Lophelia hagfish, as well as the five pairs of gill pouches.

Myxine mcmillanae, the Caribbean hagfish, is a species of hagfish. [1] It is a scaleless, eel-like fish found in Caribbean waters that feeds off material from the surface that drifts down.
