HAGFISH DAY

HAGFISH DAY

On the third Wednesday in October, Hagfish Day brings awareness to the evolved but slimy hagfish. We apologize in advance if we give you the creepy-crawlies with this National Day. But, like all other days, we should try to bring some beauty to this slimy reptile. 

#HagfishDay

Hagfish are considered to be the ugliest of species. The idea behind Hagfish Day is to encourage everyone to look beyond the exterior of the Hagfish and appreciate how highly evolved they are. Just like a book cover, you need to look deeper into the subject to hopefully form an appreciation for this species. 

The hagfish offers many benefits to the ecosystem. Despite its unappealing exterior, it scavenges the ocean floor, cleaning up the debris of dead marine animals. The slime they produce protects them from predators. While it's thinner than human hair, the slime is stronger than nylon. Researchers are seeking the potential commercial, medical and environmental uses of slime. 

The military also sees its potential. For example, Navy researchers developed a synthetic hagfish slime using E.coli bacteria. U.S. Biochemist Dr. Josh Kogot and materials engineer Dr. Ryan Kincer hope the strong synthetic slime can provide added protection for naval vessels. 

In some cultures, this eel is even considered a delicacy. Though the meat is mild, it can have a bitter aftertaste. National Day Calendar employees love food holidays, but we have all decided to take the word of anyone who has tried Hagfish versus trying it ourselves.
