单词	hagfish
释义	hagfish /ˈhaɡfɪʃ / noun (plural same or hagfishes) A primitive jawless marine vertebrate distantly related to the lampreys, with a slimy eel-like body, a slit-like mouth surrounded by barbels, and a rasping tongue used for feeding on dead or dying fish. Class Myxini and family Myxinidae: several genera, in particular Myxine, and numerous species. In contrast, the vertebrate insulin gene became a metabolic regulatory action of insulin early during vertebrate evolution since insulin regulates glucose homeostasis even in hagfishes and lampreys.... These first vertebrates lacked jaws, like the living hagfish and lampreys. They are represented now only by the lampreys, eel-like forms that are parasites on fish, and the hagfish, also eel-like but feeding on dead or dying animals. Origin Early 17th century: from hag1 + fish1.
