Echinoderms
An echinoderm () is any member of the phylum Echinodermata (). The adults are recognisable by their (usually five-point) radial symmetry, and include starfish, brittle stars, sea urchins, sand dollars, and sea cucumbers, as well as the sea lilies or "stone lilies". Adult echinoderms are found on the sea bed at every ocean depth, from the intertidal zone to the abyssal zone. The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates. Echinoderms are the largest entirely marine phylum. The first definitive echinoderms appeared near the start of the Cambrian. The echinoderms are important both ecologically and geologically. Ecologically, there are few other groupings so abundant in the biotic desert of the deep sea, as well as shallower oceans. Most echinoderms are able to reproduce asexually and regenerate tissue, organs, and limbs; in some cases, they can undergo complete regeneration from a single lim ...

Astropectinidae
The Astropectinidae are a family of sea stars in the order Paxillosida. Usually, these starfish live on the seabed and immerse themselves in soft sediment such as sand and mud. They are not to be confused with species in the genus ''Archaster'', which share similar shape and life habits, but belong to the family Archasteridae (order Valvatida). Genera There are 27 genera in the family: * '' Astromesites'' Fisher, 1913 * '' Astropecten'' Gray, 1840 * ''Astropectinides'' Verrill, 1914 * '' Bathybiaster'' Danielssen & Koren, 1883 * '' Blakiaster'' Perrier, 1881 * ''Bollonaster'' McKnight, 1977 * '' Bunodaster'' Verrill, 1909 * ''Craspidaster'' Sladen, 1889 * ''Ctenophoraster'' Fisher, 1906 * ''Ctenopleura'' Fisher, 1913 * ''Dipsacaster'' Alcock, 1893 * ''Dytaster'' Sladen, 1889 * '' Koremaster'' Fisher, 1913 * '' Leptychaster'' E.A.

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...
