Coscinasterias Calamaria
''Coscinasterias calamaria'', or the eleven-armed sea star, is a starfish in the family Asteriidae. It was thought to be endemic to southern Australia and New Zealand but has since been documented as occurring in the Cape Peninsula as well. It is found around low tide levels and deeper, under rocks and wandering over seaweed in pools. Description ''Coscinasterias calamaria'' is the largest starfish in southern Australia and New Zealand. Although called the eleven-armed sea star there can be any number of arms between seven and fourteen, but eleven is the most common number. These starfish are often found with arms of varying lengths. This is because arms sometimes become detached and new arms grow in their place. This starfish has rows of pincer-like pedicellariae on both its upper and lower surface which gives it a prickly appearance. Its total diameter is up to . Distribution ''Coscinasterias calamaria'' is native to the coasts of Australia and New Zealand. Its range extends ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Coscinasterias muricata'' is a species of starfish in the family Asteriidae. It is a large 11-armed starfish and occurs in shallow waters in the temperate western Indo-Pacific region. Description ''C. muricata'' is the largest starfish in southern Australia and can reach a diameter of . It has seven to fourteen arms, with eleven being the commonest number. The aboral (upper) surface of the arms has longitudinal rows of short spines along the surface and margins and the oral (lower) surface has two rows of tube feet. The colour is orange mottled with shades of blue, green, grey and reddish-brown. This starfish is prone to shedding its arms, making it asymmetric until new arms have grown. Distribution and habitat ''C. muricata'' is native to temperate parts of the western Indo-Pacific region. Its range extends in Australia from Houtman Abrolhos in Western Australia to southern Australia, Tasmania and eastern Australia as far north as Port Denison in Queensland. It is also fo ...

Asteriidae
The Asteriidae are a diverse family of Asteroidea (sea stars) in the order Forcipulatida. It is one of three families in the order Forcipulatida.

Addison Emery Verrill
Addison Emery Verrill (February 9, 1839 – December 10, 1926) was an American invertebrate zoologist, museum curator and university professor. Life Verrill was born on February 9, 1839 in Greenwood, Maine, the son of George Washington Verrill and Lucy (Hillborn) Verrill. As a boy he showed an early interest in natural history, building collections of rocks and minerals, plants, shells, insects and other animals. When he moved with his family to Norway, Maine at age fourteen he attended secondary school at the Norway Liberal Institute. Verrill started college in 1859 at Harvard University and studied under Louis Agassiz. He graduated in 1862 with a B.A. He went on scientific collecting trips with Alpheus Hyatt and Nathaniel Shaler in the summer of 1860 to Trenton Point, Maine and Mount Desert Island and in the summer of 1861 to Anticosti Island and Labrador. In 1864 Verrill made reports on mining, or prospective mining, properties in New Hampshire, New York, and Pennsylvania. Tw ...

Sea Star
Starfish or sea stars are Star polygon, star-shaped echinoderms belonging to the class (biology), class Asteroidea (). Common usage frequently finds these names being also applied to brittle star, ophiuroids, which are correctly referred to as brittle stars or basket stars. Starfish are also known as asteroids due to being in the class Asteroidea. About 1,900 species of starfish live on the seabed in all the world's oceans, from warm, tropics, tropical zones to frigid, polar regions of Earth, polar regions. They are found from the intertidal zone down to abyssal zone, abyssal depths, at below the surface. Starfish are marine invertebrates. They typically have a central disc and usually five arms, though some species have a larger number of arms. The aboral or upper surface may be smooth, granular or spiny, and is covered with overlapping plates. Many species are brightly coloured in various shades of red or orange, while others are blue, grey or brown. Starfish have tube fee ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Sclerasterias Dubia
''Sclerasterias'' is a genus of starfish in the family Asteriidae. Adult individuals have five arms but small, immature individuals have six. This led to the giving of a separate generic name to the juveniles, ''Hydrasterias'', before it was realised that only one genus was involved. These young individuals often undergo fissiparity. The disc splits into two parts, each bearing three arms, and new arms develop on each part to complete the complement of arms. This sometimes happens repeatedly and may be an adaptation to life in cold, deep seas where most of the species are found. Species The following species are accepted by the World Register of Marine Species: * '' Sclerasterias alexandri'' (Ludwig, 1905) * '' Sclerasterias contorta'' (Perrier, 1881) * '' Sclerasterias dubia'' (H. L. Clark, 1909) * '' Sclerasterias eructans'' (McKnight, 2006) * '' Sclerasterias euplecta'' (Fisher, 1906) * '' Sclerasterias eustyla'' (Sladen, 1889) * '' Sclerasterias guernei'' Perrier, 1891 * ...
