Hagfish, the class Myxini (also known as Hyperotreti), are eel-shaped, slime-producing marine fish (occasionally called slime eels). They are the only known living animals that have a skull but no vertebral column. Along with lampreys, hagfish are jawless; they are the sister group to vertebrates, and living hagfish remain similar to hagfish from around 300 million years ago.
The classification of hagfish has been controversial. The issue is whether the hagfish is itself a degenerate type of vertebrate-fish (most closely related to lampreys), or else may represent a stage which precedes the evolution of the vertebral column (as do lancelets). The original scheme groups hagfish and lampreys together as cyclostomes (or historically, Agnatha), as the oldest surviving class of vertebrates alongside gnathostomes (the now-ubiquitous jawed vertebrates). An alternative scheme proposed that jawed vertebrates are more closely related to lampreys than to hagfish (i.e., that vertebrates include lampreys but exclude hagfish), and introduces the category craniata to group vertebrates near hagfish. Recent DNA evidence has supported the original scheme.
Richard Mark Hammond (born 19 December 1969) is a British presenter, writer, and journalist. He co-hosted the motoring programme Top Gear with Jeremy Clarkson and James May, from 2002 to 2015 and presented series 1–4 of Brainiac: Science Abuse on Sky1. He also co-hosted Total Wipeout with Amanda Byram on BBC One. Hammond presented Planet Earth Live alongside Julia Bradbury. In 2016 he was scheduled to be presenting an Untitled Amazon motoring show to be produced by their company W. Chump & Sons alongside his former Top Gear co-hosts, as an exclusive distributed via Amazon Video to Amazon Prime customers.
Hammond was born in Solihull, West Midlands, and is the grandson of workers in the Birmingham car industry. In the mid-1980s Hammond moved with his family (mother Eileen, father Alan, and younger brothers Andrew, writer of the 'Crypt' Series, and Nicholas) to the North Yorkshire cathedral city of Ripon where his father ran a probate business in the market square. He attended Blossomfield Infant School in Shirley from the age of 3-7. Originally a pupil of Solihull School, a fee-paying boys' independent school, he moved to Ripon Grammar School, and from 1986 to 1988 attended Harrogate College of Art and Technology.

Hagfishes (Myxinidae) are a family of jawless marine pre-vertebrates. Those video images taken in New Zealand revealed that hagfishes are able to choke their would-be predators with gill-clogging slime.It also shows that hagfishes are actively preying on other fish in New Zealand waters. The video is part of a scientific paper describing this newly discovered behaviour which can be downloaded online at http://www.nature.com/srep/2011/111027/srep00131/full/srep00131.html Zintzen V., Roberts, C.D., Anderson M.J., Stewart A.L., Struthers C.D. & Harvey E.S.

On an expedition in the Gulf of Mexico, Dr. Dean Grubbs from Florida State University, dissects a deep sea hagfish. To watch his team from FSU's Coastal Marine Lab in action, check out the "Changing Seas" episode "Creatures of the Deep" now: https://www.youtube.com/watch?v=WEIqgFUxV2g&list;=UU2L3PrUh7nWFA_Fva8RoGcA
Slime, or mucus is used by many animals both on land and in the sea, but Hagfish have the outstanding ability to defend themselves by producing an incredible slime when touched. It comes from the glands along the side of their body, and within minutes literally liters of it can be produced. Despite being one of the most primitive vertebrates alive, this rare species is certainly strange and wonderful! Our oceans harbor amazing species that despite being a bit weird, are still worth protecting.
The hagfish found in New Zealand's deepest waters is grotesque enough, thanks to its scary protruding teeth straight from a horror film. Now, scientists have witnessed the full power of its other gruesome feature -- a built-in slime weapon to deter predators such as sharks, making it one of the planet's ultimate survivors.
Don't worry the Hagfish is not hurt, it's just anaesthetised.
Celebrate the Ugly! In general, people love animals with big eyes, soft fur, beautiful feathers or friendly behaviour. But an ecosystem needs everything! Even organisms as unattractive as the hagfish. These rather gross, pink sausages are the slimy scavengers of the deep. With astonishing capabilities: They can transform a bucket of water into a gooey slime within seconds, they mostly feed on dead animals which they enter via mouth, gills, eyes or other unspeakable openings and have a face that only a mother can love. They can tie themselves in a knot, can survive months without feeding and fend off even much larger predators by the use of their slime, clogging the gills of an attacker. In 2009, the "International Hagfish Day"...
