The Atlantic Hagfish has a number of unique features. Plenty of discussions on the evolutionary information and the morphology of the Myxine Glutinosa eyes, some scientists were trying to compare it with the retina of lampreys. The Atlantic Hagfish possesses a more ancestral vertebrate eye form, and the lamprey possesses a more derived form.
Hagfish embryos have characteristics of gnathostomes and may be plesiomorphic; [33] however, these characteristics drastically change morphologically as the hagfish matures. [33] The following hagfish and lamprey phylogeny is an adaptation based on the 2019 work of Miyashita et al. [ 69 ]
The size of captured specimens ranges between 91 and 394 mm. The southern hagfish is found in the cold waters of the Southwestern Atlantic Ocean from the coasts off Southwestern Brazil down to the Southern Ocean and the Tierra del Fuego and the Patagonian coasts of Chile and Argentina, including the Strait of Magellan.

Age of the bedrock underlying North America, from red (oldest) to blue, green, yellow (newest). Seventy percent of North America is underlain by the Laurentia craton, [5] which is exposed as the Canadian Shield in much of central and eastern Canada around the Hudson Bay, and as far south as the U.S. states of Michigan, Wisconsin, and Minnesota.

South of the Arctic, Europe and North America are separated by the North Atlantic. In terms of associating its oceanic islands with either continent, the boundary is usually drawn between Greenland and Iceland and between Bermuda and the Azores' Grupo Ocidental (Western Group)—all other North Atlantic islands are continental.
