Hagfish Day

Hagfish slime is incredibly strong and stretchy. Scientists are exploring its use in creating biodegradable plastics, military body armor, and even artificial tissues for medicine.

The slime contains protein threads thinner than human hair but tougher than nylon. Some researchers believe it could replace petroleum-based materials in clothing or industrial applications​.

Yes! In Korea, hagfish is a popular dish. It is typically grilled alive, then seasoned with spices.

Some even eat it raw or use the slime as a thickener in soups. The texture is chewy, and the flavor is compared to eel. However, due to overfishing, hagfish populations are declining in some areas​.

Hagfish appear in folklore in some Asian cultures, often as symbols of persistence due to their ability to survive in extreme conditions.

In Japan, they are sometimes called “shokko,” meaning “food thief,” since they sneak into fish traps and steal the catch​.

One odd myth is that hagfish are immortal because they have existed for 300 million years with little evolution.

In reality, they just have an ancient body design that has proven effective over time. Another misconception is that they are eels; they are actually more closely related to lampreys​.

Hagfish can tie themselves into knots! This helps them slip out of a predator’s grip or remove excess slime from their bodies.

Some hagfish also twist into a knot to anchor themselves while feeding inside carcasses​.

Some marine biology enthusiasts host slime-making contests using cornstarch and water to mimic hagfish slime.

Others prepare hagfish-inspired dishes. In 2017, a group of scientists created a hagfish-themed escape room where participants had to “slime” their way out​.

Yes! In 2017, a truck carrying thousands of live hagfish overturned in Oregon, spilling them onto a highway.

Their slime coated the cars, causing accidents and making cleanup difficult. The event, dubbed “The Slime Spill,” became a viral news story​.

Hagfish live in deep, oxygen-poor waters, some as deep as 16,000 feet.

They can survive for months without food and tolerate high levels of carbon dioxide, making them among the most resilient marine creatures​.

Most predators avoid hagfish because their slime can suffocate them.

However, some sharks have learned to bite the hagfish, then shake it violently to remove the slime before eating it. This adaptation helps sharks avoid choking on the goo​.

Hagfish feeding behavior helps scientists estimate time of death for corpses found in water.

Since they eat from the inside out, researchers study how quickly they consume tissue to determine how long a body has been underwater​.
