Hagfish: Slime Eel

The Hagfish is a marine worm-like creature. Despite its gruesome appearance, they are most known for the sticky slime they can make. They are called slime-eels, but they are not related to eels at all. Instead, there is a debate whether the Hagfish is strictly a fish. There are about 60 species of them, belonging to the class of Myxini, and Myxinidae is the name of the Hagfish family. They are found in oceans in many parts of the world.

Hagfish: Habitat & Characteristics

Hagfish are lazy creatures that are sometimes found hiding under rocks and crevices. They nest in holes on the seabed, usually just found by the Hagfish. Unless they are disturbed or hungry, they won’t leave the nest. When Hagfish produce slime, they secrete a micro fibrous material into the water that is actually white and liquidly. The material comes out of white holes along the Hagfish’ body. When mixed with water, just a few drops could turn a cup into slime after mixing. You can see many sliming videos on Youtube. A grown Hagfish can have enough micro fibrous material to turn a 5 gallon bucket of water into complete slime in about five minutes. However, Hagfish do have a limit of how much slime they can produce. The slime is mainly used for self-defense, because when touched by a predator or aggravated, the Hagfish will start “sliming”. This method is to distract predators and help them wriggle out of grasp, leaving the slime behind. The slime will disturb and even choke a predator if swallowed. To escape predators, they also use a “knot” method, where they tie into a knot and squeeze themselves away. This is very effective in a difficult situation. Hagfish do indeed have eyes, and only a single nostril. The eyes are extremely poor in sight, without the ability to make out any images. But it is believed that they can detect light.

Hagfish: Diet & Eating Habit

Hagfish have a varied diet of dead animal matter. They will usually eat any meat they can find. Food is not rare though. Hagfish have small, comb-like teeth that are designed to rip flesh. The meat is then swallowed whole. However, the Hagfish aren’t complete scavengers, but also parasitic fish. They find live food and grab onto it, slowly eating into the victim alive, even when it’s still alive. Only the skin and bones remain. Hagfish are rather abundant, with no natural predators.

Hagfish Reproduction

Scientists are still trying to find out more about Hagfish reproduction. There is about one male for every 100 Hagfish. Some Hagfish even have one ovary, and one testicle in reproduction. The ovary is inactive for a while until the Hagfish is a certain age. Hagfish lay around 20-30 squishy yellow eggs and are sometimes seen brooding their own eggs. The fry that hatch are small and worm like, and are left alone by predators. With these combined factors, Hagfish have a high success rate.
