A recently discovered ancient aquatic lifeform, known as hagfish is sometimes labelled as disgusting due to its slime producing capabilities. Hagfish average about half a metre. When captured and held e.g. by the tail, they secrete the microfibrous slime, which expands into a gelatinous and sticky goo when combined with water; if they remain captured, they can tie themselves in an overhand knot which works its way from the head to the tail of the animal, scraping off the slime as it goes and freeing them from their captor, as well as the slime. While marine worms on or near the sea floor are a major source of nutrition, hagfish can feed upon and often even enter and eviscerate the bodies of any injured creature much larger than themselves. They are known to devour their victims from the inside. Recently a few couple of cases have been noted when human deadbodies were found in sea shaped like a stocking without any mass. The predator was found to be hagfish.
4. Moral Eels
Moray eels mostly live in salt water. They can grow upto 4 meters in length. The body of Moray Eel generally patterned. Camouflage is also present inside the mouth. Their jaws are wide, framing a protruding snout. They possess large teeth, designed to tear flesh as opposed to holding or chewing. Morays hide from humans and would rather flee than fight. Morays are shy and secretive, and attack humans only in self-defense or mistaken identity (for example, a finger placed in a crevice where a moray resides may resemble a prey-item). Most attacks involve accidental bites during human-initiated interaction. Morays cannot see very well and rely mostly on their acute sense of smell.
3. Puffer Fish
These funny looking Puffer fish are the second most poisonous vertebrates on earth after the Golden Poisonous frog. The puffer’s skin and certain internal organs are highly toxic to humans. Deadly poison called Tetrodotoxin (TTX) is contained Puffer fish. Toxins are more powerful than cyanide resulted in difficulty in breathing on a person before leading to death. Still in some parts of Japan and Korea chef’s remove the poisonous part and meat allowing it to be served as meal.

1. Blue Ringed Octopus
The blue ringed octopus is tiny and beautiful. Its amazing rings flash a rich fluorescent blue. An individual blue-ringed octopus tends to use its dermal chromatophore cells to camouflage itself until provoked, at which point it quickly changes color, becoming bright yellow with blue rings or lines. Should you run across this tiny vividly colored octopus, you may think to grab it to take home to your salt water tank. Grabbing it for your salt tank might be a deadly mistake. The blue-ringed octopus is 5 to 8 inches, but its venom is powerful enough to kill humans and there is no blue-ringed octopus anti-venom available. They pounce on their prey, paralyze them with venom and use their beaks to tear off pieces. They then suck out the flesh from the body. Once bitten, the fast acting poison leads to loss of sight, taste and touch immediately. Without quick treatment, the paralysis will cause asphyxial death because of respiratory paralysis.
