Characteristics

Paxillosida adults lack anus and suckers on the tube feet and do not develop the brachiolaria stage in early development [Matsubara, M., Komatsu, M., Araki, T., Asakawa, S., Yokobori, S.-I., Watanabe, K. & Wada, H.

ystematics

Recent analyses suggest that Paxillosida may be a sister taxon of Asterina [Matsubara, M., Komatsu, M., Araki, T., Asakawa, S., Yokobori, S.-I., Watanabe, K. & Wada, H. (2005) The phylogenetic status of Paxillosida (Asteroidea) based on complete mitochondrial DNA sequences. Molecular Genetics and Evolution, 36, 598–605] . The order is divided into the following families [ [http://www.marinespecies.org/aphia.php?p=taxdetails&id=123088 MarineSpecies.org - Paxillosida Perrier, 1884 ] ]
* "Astropectinidae"
* "Ctenodiscidae"
* "Goniopectinidae"
* "Luidiidae"
* "Porcellanasteridae"
* "Radiasteridae"
