why is myxine called hagfish?
The species Myxine glutinosa was named for this slime. When captured and held, e.g., by the tail, they secrete the microfibrous mucus, which expands into up to 20 litres (5¼ US gallons) of sticky, gelatinous material when combined with water; one litre of slime has about 40 milligrams of mucus and proteins.
