Loricifera is a phylum of free living, microscopic animals found exclusively Pliciloricidae) and a ghost-larva with paedogenetic reproduction.
Loriciferans (phylum Loricifera) are meiofauna - tiny organisms which Loriciferans are fee-living and dwell in coarse sediments.
Reproduction and Growth.
The Higgins larvae may have a very patchy distribution. Three pairs of setae are located toward the rear of the abdomen.

Since muscle fibers were not found inside the toes of Armorloricus elegansthe movement of these locomotory structures is probably controlled by the triangular posteroventral muscle and the inner pairs of the posteriormost short longitudinal muscles, because of their arrangement in close proximity to the posterior toes.

The thoracic region is usually concealed inside the cuticular exoskeleton called the lorica and lacks appendages. Loricifera is a phylum of free living, microscopic animals found exclusively in the marine environment [ 1 ]. Likewise, the mouth cone and buccal tube retractors found in Nanaloricus sp.

They are found in large numbers in areas where methane seeps from the sediment.

|Two previously published records from Florida and the Azores Islands respectively turned out to refer to two undescribed species.
There are several flosculi of the Nanaloricus-type on the abdomen of the Higgins larva. The members of the family Pliciloricidae follow two different life cycles, named the Rugiloricus cauliculus and Rugiloricus carolinensis cycles respectively.
The accordion-like thorax consists of 5—6 folds. This composition contrasts to the situation in Nanaloricus sp.
Observers have noticed that the mouth cone telescopes out to its full length, fastens itself to a sand grain, and then draws in again so that the loriciferan's body is pulled forward.
