How did the hagfish get its name?

When Alvin pilot Bruce Strickrott captured a specimen of the worm-like fish during a dive in the cold, inky Pacific depths in March 2005, he recalled thinking it was “cool … but in a hideous sort of way.” About a year later, he learned scientists wanted to name it for him.

Why is the hagfish special?

Hagfish are the only animals with a cranium but no spinal column. They do have a cartilaginous notochord—a skeletal rod that most vertebrates lose in utero—that gives them amazing flexibility. For instance, if a predator gets a good hold on a hagfish, the animal can wriggle out of its grasp by tying itself into a knot.

Which adjective best describes the Myxini?

The adjective which best describes the Myxini is “Lovecraftian”. Hagfish are long, slender and pinkish, and are best known for the large quantities of sticky slime which they produce. Hagfish have three accessory hearts, no cerebrum or cerebellum, no jaws or stomach, and will “sneeze” when their nostrils clog with their own slime.

The Myxini are unique among living chordates in that they have a partial cranium (skull), but no vertebrae, and so they are not truly vertebrates. The skeleton is composed of cartilage, and lacks bone.

What is the larval stage of a Myxini?

Unlike many other fish, the Myxini undergo direct development, with no larval stage. The newly hatched young are practically miniature versions of their parents. Young are hermaphroditic at first, bearing both sets of sex organs; later in life, they will be either male or female, but may change sex from season to season.

Are osmolytes present in Myxini?
