Micrognathozoa — a new microscopic animal group from Greenland
During a field course in arctic biology held on Disko Island, Greenland, a new animal was recorded from a cold spring near Isunngua on the eastern part of the island.
Funch named the animal Limnognathia maerski and placed it in a new group called Micrognathozoa.

Scientists from Copenhagen University and Aarhus University in Denmark have established a new phylum -- or family -- for the tiny animal, whose most remarkable feature is a set of very complicated jaws.
It has now got its own branch, Micrognathozoa, on the tree of the world's known animals, which are divided into slightly more than 30 families, Polarfronten said.
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.

Gnathiferans have a complex pharynx with a cuticular jaw apparatus operated by an elaborate pharyngeal musculature.
The taxon includes Rotifera, Gnathostomulida, Micrognathozoa, Acanthocephala, and Seisonida.
Rotifers, seisonidans, and acanthocephalans share a syncytial epidermis with an cytoplasmic skeleton known as the intrasyncytial lamina (Fig 23-12).

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.
maerski are distinct enough to allow the description of a new phylum, Micrognathozoa.

The structure of trophi vary greatly among rotifer groups and is related to feeding mode, some are used for grinding food captured by suspension feeding (such as diatoms), others are raptorial and serve carnivorous species, yet others are suctorial, creating a piston-like action.
Two other phyla with similar cuticularized pharyngeal jaws are known (Gnathostomulida and Micrognathozoa) and appear to be the closest relatives of rotifers, suggesting a common origin to these structures.
