MYXINI Description: 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. They are found in cold ocean waters, scavenging dead and dying fish but also preying on small invertebrates. Hagfish are almost blind, but have well developed senses of touch and smell. They have four pairs of sensing tentacles arranged around their mouth. The mouth lacks jaws, but a hagfish is equipped with two pairs of tooth-like rasps on the top of a tongue-like projection. 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. Hagfish eggs are approximately one inch long, and encased in a tough shell. Examples 1. Eptatretus stouti - Pacific Hagfish
