Once found mainly in the north east Atlantic, in recent years the fish have tended to head north west towards Iceland and the Faroe Isles following their prey of squid and crustaceans.
In some cases, their jobs are carried over from past show-within-a-show Muppet joints, while other characters have been shunted off to an "Up Late" writers' room populated by motley talking vermin and crustaceans.
Over the course of three field trips, researchers unearthed 12 of these cream-coloured, leggy arthropods - a class of creatures with segmented bodies and jointed legs that includes spiders, insects and crustaceans.

The plants create a habitat for creatures like protozoans and microscopic crustaceans that eat the dead and dying bacteria.
Non-fish groups include whales, dolphins, seabirds, squid, echinoderms, benthic crustaceans and small worms.

But the analysis by Kruta and her colleagues indicates their ammonites would have dined on small organisms floating in the water, such as zooplankton, tiny crustaceans, and even other petite ammonites.
Given that Crassicorophium and barnacles are both crustaceans, albeit ones whose common ancestor lived 100m years ago, that suggests a single origin for the ability to make this type of goo.
Researchers were inspired by the advanced eyes of arthropods, a group that includes crustaceans, spiders and insects.
It sits in the middle of the Japan current, a nutrient-rich stream that feeds a stunning variety of crustaceans, tropical fish and other sealife.
We would remove the shells and inedible innards, then briefly oven-bake the crustaceans in a bath of garlic, oregano, olive oil, butter and white wine.
He said the subject of pain in crustaceans was "controversial" and a matter of data interpretation.
"There has been a long debate about whether crustaceans including crabs, prawns and lobsters feel pain, " said Professor Elwood in a press statement.
And given that the krill (tiny crustaceans) that penguins feed on are also dependent on the ice for their own existence (they feed on algae on the ice) - some colonies affected by eroded floes could face a double-whammy of high fledgling mortality and restricted food resources.
The Independent Shell Fisherman's Cooperative said the crustaceans had been stranded between Fraisthorpe and Barmston.
Krill (crustaceans resembling prawns) subsist on phytoplankton and are in turn eaten by fish, squid, jellyfish, seabirds, penguins, seals, whales and other animals.
However, the unknown species are composed disproportionately of groups of macroinvertebrates, with tens of thousands of species of smaller crustaceans, molluscs (snails) worms and sponges awaiting discovery.
But Professor Elwood says that in contrast to mammals, little protection is given to the millions of crustaceans that are used in the fishing and food industries each day.
For example, in a study published last year in the Proceedings of the National Academy of Sciences a group of researchers looked at crustaceans (crabs, shrimps, woodlice and so on) over the past 550m years and found far more examples of groups of species evolving towards complexity than in the other direction.
In the evening, she fished for crustaceans, which she cleaned, boiled, and served to the others.
The crustaceans had been stranded last week between Fraisthorpe and Barmston, the Independent Shell Fisherman's Cooperative had said.
They say they now believe that all decapod crustaceans - a group that also includes lobsters and crayfish - would show the same response.
Her research has focused on pain in fish, and said there were further avenues that the team could explore with crustaceans.
These are crustaceans that survive by dragging around a cast-off mollusc shell for protection and shelter.
Up to 1, 000 of the crustaceans, donated by the National Lobster Hatchery based in Cornwall, will be released between June and August.
