Etymology: Myxine: Ancient Greek word for a slimy fish: myxa, slime; -inus, one who, referring to copious amounts of slime produced by M. glutinosa (See ETYFish); greggi: In honor of John Gregg, founder and president of the Western Flyer Foundation, an “ardent supporter of marine biology research and a hagfish enthusiast. He joined the team during part of the Galapagos expedition and was on the boat when the specimens were collected.” (See ETYFish).
Eponymy: John Gregg is an American marine geologist who founded (1985) the Gregg Drilling company. [...] (Ref. 128868), visit book page.
