== Myxini ==

'''Myxini''' (pronounced: mix-ee-nee), also known as '''hagfish''', are a class of jawless fish, the only known living animals that have a skull but no vertebral column. 

=== Etymology ===

The term "Myxini" is derived from the Greek word "myxa", which means "mucus" or "slime", a reference to the notable slime-producing capabilities of these creatures.

=== Anatomy ===

Myxini are known for their unique anatomy. They possess a cartilaginous skull and tooth-like structures composed of keratin. Unlike other vertebrates, they lack paired fins and true vertebrae. They have elongated, eel-like bodies, and paddle-like tails.

=== Behavior ===

Myxini are known for their peculiar defensive mechanism. When disturbed, they secrete a slime from their skin that, when combined with water, expands into a gelatinous and sticky goo. This slime can clog the gills of predatory fish, thereby discouraging predation.

=== Habitat ===

Myxini are marine creatures, found in cold waters across the globe. They are benthic animals, meaning they live and feed on the sea floor.
