Echinoderm
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 limb. ...

Micropetalon
''Stellaria'' is a genus of about 190 species of flowering plants in the family Caryophyllaceae, with a cosmopolitan distribution. Common names include starwort, stitchwort and chickweed. Description ''Stellaria'' species are relatively small herbs with simple opposite leaves. It produces small flowers with 5 sepals and 5 white petals each usually deeply cleft, or none at all, all free. Stamens 10 or fewer. Uses Some species, including '' Stellaria media'' which is widely distributed throughout the Northern Hemisphere, are used as leaf vegetables, often raw in salads. This is a favored food of finches and many other seed-eating birds. Chickweeds are used as food plants by the larvae of some Lepidoptera species including angle shades, heart and dart, riband wave, setaceous Hebrew character and the ''Coleophora'' case-bearers ''C. coenosipennella'' (feeds exclusively on ''Stellaria'' species), ''C. lineolea'' (recorded on ''S. graminea''), ''C. lithargyrinella'' (recorded on '' ...
