  Limnognathia - Wikipedia, the free encyclopedia
Limnognathia maerski is a microscopic animal, discovered living in homothermic springs on Disko Island, Greenland in 2000, that was given its own phylum, Micrognathozoa.
While feeding, limnognathia extend jaw parts from the mouth to grasp the substrate, like two small hands.
It also has many other unique bodily structures which earned it its own phylum.

 Completely new animal found in Greenland
The 0.1 millimetre long freshwater organism does not fit into any one of the previously known animal families -- making it only the fourth such creature to be discovered on the planet in the past 100 years, Polarfronten said.
Studies of the animal named "Limnognathia maerski" show that it shares some characteristics with certain seawater life-forms.
Limnognathia maerski, which reproduces through parthenogenesis, uses its jaws to scrape the bacteria and algae it feeds on from underwater moss growing in icy wells which freeze over during the long Arctic winter.

 SICB - 2004 meeting - Abstract Details   (Site not responding. Last check: 2007-10-25)
Micrognathozoans were first discovered in 1994 by Reinhardt Kristensen and Peter Funch after an analysis of the meiofauna of a cold freshwater spring on Disko Island, Greenland.
The only described micrognathozoan species, Limnognathia maerski, is a small, soft-bodied animal with scleroterized jaws similar to those found in members of Gnathifera (= Rotifera and Gnathostomulida).
Some studies have suggested that Micrognathozoa is the sister group to Rotifera, whereas others have implied stronger affinities with Gnathostomulida.

 Genome Biology | Full text | A new profusion of planktonic eukaryotes
Zoologists may assume that they have described the vast majority of higher taxa, but the last new animal phylum distinguished, the Cycliophora, was discovered only in 1995, and another unusual organism, Limnognathia maerski, was described only in 2000.
It would be intriguing to see what molecular techniques would reveal lurking among the meiofauna, where Limnognathia and the Loricifera, another recently described phylum, were found.
I am sure that other biologists can think of other environments where new members of their favourite taxonomic group could be uncovered by similar experiments.

The sole known species of the group, Limnognathia maerski, was originally reported from running freshwater in Disko Island (Greenland), and has recently been recorded from the subantarctic region.
Because of the presence of a particular type of jaws formed of special cuticularized rods, similar to those of gnathostomulids and rotifers, the three metazoan lineages were considered closely related, and assigned to the clade Gnathifera.
However, the exact position of Micrognathozoa could not be determined due to the lack of support for any given relationships and due to the lack of stability in the position of Limnognathia maerski under analysis of different loci and of different parameter sets for sequence comparison.

A freshwater animal discovered in the frigid springs of Disko Island, West Greenland, puts even the great white shark to shame.
With 32 moving parts, the jaw of this microscopic invertebrate, named Limnognathia maerski by it's Danish founders, not only exceeds sharks in its complexity, but any other known invertebrate.
While feeding, the animal extends jaw parts from its mouth to grasp the substrate, like two small hands.

 Ananova - Scientists find new animal in a well
The freshwater lifeform that shares some characteristics with other sea-life is only the fourth creature in 100 years not to fit into previously known animal families.
Scientists from Copenhagen University and Aarhus University in Denmark have created a new family name for the animal they have called "Limnognathia maerski" which measures just 0.1 mm.
The animal feeds by using its complicated set of jaws to scrape bacteria and algae from underwater moss in cold wells, the Arctic magazine Polarfronten reports.

The microscopic invertebrate belongs to a brand new category of animals and may even be a missing link between known classes of marine creatures.
Called Limnognathia, this animal is only a tenth of a millimeter long, and a full third of that length consists of its extraordinarily complicated jaw.
Previous investigations on Disko Island focused on warm springs, not the cold springs where Limnognathia lives, frozen solid for half the year under six feet of snow.

 Nyt Dyr Fundet I Kilde På Grønland (New Animal Found In Greenland)
This is the claim of Danish scientists who found a small (0,1mm) creature in a well in Greenland.
They had to create a new phylum (family) for Limnognathia maerski, (see picture) which is only the fourth such creatures discovered in the past hundred years.
Its outstanding feature is a set of very complicated jaws.

The scientists discovered a previously unknown type of animal down a cold well in Greenland.
The 0.1-millimetre Limnognathia maerski, is one of only four new life forms discovered in the past hundred years.
Its most noteworthy aspect is its jaws, used for scraping the algae and bacteria it feeds on from moss.

If we closed our eyes and never explored the world around us, then the new type of animal discovered on October 13, 2000, by a group of Danish scientists, would never have been discovered.
These little freshwater organisms named "Limnognathia Maerski" were discovered living, feeding, and reproducing among the icy waters of a Greenland well.
They seem to share some similarities with certain seawater life-forms, yet don't fit the mold of any known animal family.

 Limnognathia
Several specimens of the animal were picked up and transported to the laboratories on the Zoological Museum in Copenhagen.
Here the animals were investigated in details using transmission and scanning electron microscopy, and based on these investigations Kristensen and Funch described the new animal, named it Limnognathia maerski and placed it in its own newly established group called Micrognathozoa.
