Abstract The eyes in three genera of hagfish (Eptatretus, Paramyxine andMyxine) have been investigated with the light microscope. A comparison of the eyes, their location and retinal organization shows that among hagfishes an evolutionary trend towards reduction of the visual capability and a degeneration of the eyes is evident.Eptatretus represents the plesiomorphic andMyxine the apomorphic condition, whereasParamyxine holds an intermediate position. The different degenerative stages of the… Expand
First Fossil Hagfish (Myxinoidea): A Record from the Pennsylvanian of Illinois
TLDR
A fossil hagfish (Myxinoidea), a new genus from the Pennsylvanian, shows tentacles, structures of the head skeleton and internal organs, and it is quite similar to its recent relatives. Expand
The Cyclostome Retina
TLDR
Hagfishes and lampreys are vertebrates classified systematically as Agnatha (jawless) or Cyclostomata (round-mouths) but most research on retinas of vertebrates has been carried out on species which belong to the gnathostomes and this has led to generalizations which are not always valid for the agnaths.

Ontogeny of the head of the Pacific hagfish (Eptatretus stouti, Myxinoidea): development of the lateral line system.

TLDR
It is found that an embryonic lateral line system is present in hagfishes, and that the grooves of adult hagFishes in all probability derive from lateral line placodes, which is a primitive character of craniates. Expand
A New Species of Hagfish (Myxinidae: Eptatretus) Associated with Deep-Sea Coral Habitat in the Western North Atlantic
TLDR
Eptatretus lopheliae is a small hagfish species observed, videotaped, and caught in close association with Lophelia pertusa reef habitat off the southeastern United States. Expand
Vertebrate features revealed in the rudimentary eye of the Pacific hagfish (Eptatretus stoutii)
TLDR
Hagfish eyes are degenerate but not degenerating, i.e. rudimentary but growing Retinal interneurons discovered implying ancestral hagfish had derived retinas & vision; this data clarify Agnathan retinal homologies, reveal characters that now appear to be ubiquitous across the eyes of vertebrates, and refine interpretations of early vertebrate visual system evolution. Expand
Vertebrate features revealed in the rudimentary eye of the Pacific hagfish (Eptatretus stoutii)
TLDR
It is inferred that the hagfish retina is not entirely rudimentary in its wiring, despite lacking a morphologically distinct layer of interneurons, and characters that now appear to be ubiquitous across the eyes of vertebrates are revealed, which clarify Agnathan retinal homologies and refine interpretations of early vertebrate visual system evolution.

Comparative retinal morphology of the platypus
TLDR
Evaluation of opsins indicates that red and blue immunoreactive cone opsins, but not rhodopsin, are present in the most basal of the extant species examined, the Pacific hagfish, establishing emergence of this pigment in an extant relative of tetrapods. Expand
The Lateral Line System of Hagfishes (Craniata: Myxinoidea)
TLDR
It is concluded that most or all eptatretid hagfish possess a lateral line system composed of shallow trenches, or grooves, lined with a single class of flask-shaped receptive cells, representing the primitive condition for craniate lateral line organs. Expand
Conodonts: A Sister Group to Hagfishes?
TLDR
The fossil record of the conodont animal is almost exclusively represented in the fossil record by the phosphatic elements of the feeding apparatus, which was the only mineralized component of the skeleton. Expand
Gonads and Reproduction in Hagfishes
TLDR
The GnRH-like system of myxinoids is considered as a possible homologue of the caudal neuromodula-tory GnRH system of higher vertebrates and indications for the production of steroids by the gonads have been brought forth. Expand

TLDR
No color change was observed with the naked eye, nor did microscopy reveal any migration, fading, or other change in the melanophore due to the influence of light; the mortality observed in animals illuminated in white aquaria is discussed. Expand
Les yeux des Cyclostomes fossiles et le problème de l'origine des Myxinoïdes
TLDR
Evidence is offered that osteostracan possessed spheroidal eyeballs similar to those of present-day petromyzontids; also, that heterostracans were equipped with conical eyeballs closely conforming to those encountered in the recent myxinoid Eptatretus burgeri. Expand

TLDR
It is suggested that the capability of the animals to survive in white aquaria is due to the fact that the animals, after capture, were allowed to regain normal conditions in black aquaria, whereas in previous experiments the animals were directly transferred to white Aquaria after capture. Expand
