The mouth is surrounded by nine rings of bristly scales, the first set of which point forward, the rest backward.
The body is encased in several hard plates that resemble a corset, from which the group gets the name Loricifera, meaning “corset-bearer.” At the hind end of the body is an anus.

The phyla Loricifera and Priapulida are related and may be grouped in a single taxon.
In a related article by Kristensen (2000), Kinorhyncha, Priapulida and Loricifera are shown to all have chitin in the procuticle, an outer covering found in some organisms.
Loricifera have a segmented body divided into five regions - a mouth cone, head, neck, thorax and abdomen (Kristensen, 1999).

The Loricifera are minute invertebrates, rarely attaining 0.5 mm in size.
Loricifera are dioecious animals that have paired gonads.
The range for this phylum has also been extended to include the coastal regions of North America, and a global distribution seems likely.

The Loricifera were only discovered and described as a phylum in 1983, and less than a few dozen species have so far been described.
All known Loriciferans are small (less than 0.4 mm) meiofaunal animals that live in the interstitial spaces of gravel or mud sediments, and have been found in waters up to several thousand meters deep.
Although both the larvae and adults appear to be free living, very little else is known about their biology.

 Animal   (Site not responding. Last check: )
Traditionally the Arthropoda - the largest animal phylum including insects, spiders, crabs, and kin - and two small phyla closely related to it, the Onychophora and Tardigrada, have been considered close relatives of the Annelida on account of their common segmented body plan (the Articulata hypothesis).
This relationship is now in doubt, and it appears that instead they belong with various pseudocoeolomate worms - the Nematoda (roundworms), Nematomorpha (horsehair worms), Kinorhyncha, Loricifera, and Priapulida - which share with them ecdysis and several other characteristics.
There are various pseudocoelomate protostomes that are hard to classify because of their small size and reduced structure.

Among the Loricifera, Higgins and Kristensen initially described 3 genera and 5 species.
The zoologists don’t know what the Loricifera eat, either, but guess that they may subsist as parasites because their narrow snouts appear designed for piercing and sucking.
Animals that lay hundreds of eggs (such as many species of fish) can afford to abandon their offspring, since it is likely that many of their young will survive the vagaries of nature.

The discovery of phyla is truly extraordinary as the 1.5 million or so species described on the planet can all be classified into only about 43 phyla.
In 1983, the Danish zoologist, R. Kristensen discovered the phylum Loricifera living in the tiny spaces between marine gravel in sediments off the French coast.
Since then at least 10 more species have been described (with rumours of 100s under investigation!), including inhabitants of coastal areas of North America.

Loricifera -- loriciferans; about 10 species described, all microscopic
Most are soft-bodied worms, and many of them are microscopic -- in fact, practically all members of the Cycliophora, Gastrotricha, Kinorhyncha, Loricifera, and Rotifera are less than 1 millimeter long, as are many nematodes and priapulids.
On the other hand, one species of parasitic nematode can reach 13 meters in length -- it parasitizes the sperm whale -- and adult nematomorphs, chaetognaths, and some priapulids are also visible to the naked eye.

 Pharyngula
Here’s a couple of strange and obscure groups of invertebrates that most people haven’t heard of: the Priapulida, Kinorhyncha, and Loricifera, some small marine worms that have no medical significance, aren’t used as research models, tend to live in odd and inaccessible places, and each phylum has no more than a few hundred species.
They are obscure enough and so little studied that their classification is even in flux—the Loricifera were only recognized as a discrete phylum in 1983, and there is talk of reorganizing all four (including the Nematomorpha) into a single phylum.
You’ll also see the groups referred to by different names; the Cycloneuralia, the Introverta, the Scalidophora.

Sections: General characteristics; Priapulida, Kinorhyncha, and Loricifera; Arthropoda, Onychophora, and Tardigrada; Nematoda; Evolution: diversity; Evolution: genomics
A major division within the animal kingdom containing the majority of animal species and comprising the phyla Priapulida, Kinorhyncha, and Loricifera (no common names), Arthropoda (insects, crustaceans, spiders, etc.), Onychophora (velvet worms), Tardigrada (water bears), and Nematoda (roundworms).
These forms include animals with disparate morphologies, but their close relationship is suggested by molecular DNA sequence comparisons—especially of both large and small subunit RNA molecules—and is consistent with myosin heavy-chain sequence comparisons and with a variety of uniquely shared genomic and morphological features.
