Overview
Hagfish are intriguing creatures that glide through the ocean depths like little slime ninjas. These unique fish belong to the class Myxini and have been around for over 300 million years, making them ancient survivors of the sea.
Hagfish can grow to be 40 to 79 centimeters, or about 16 to 31 inches long. They have long, eel-like bodies covered in mucous, which helps them slink away from predators and escape danger like slippery superheroes.
Their diet consists mainly of small marine animals and dead fish. These savvy scavengers can sniff out a meal from afar, using their excellent sense of smell to locate food in the murky depths.
One of the coolest features of hagfish is their ability to produce large amounts of slime when threatened. This slime can fill up the mouth and gills of potential predators, making it a slippery escape for the hagfish and a rather unpleasant surprise for its would-be attackers!
Hagfish have a surprisingly long lifespan, living up to 40 years in the wild. They keep their bodies and routines simple, which might just be the secret to their longevity in the ocean's depths!
