Echinaster Modestus
''Echinaster'' is a well-studied and common genus of starfish containing ~30 species and is the second-largest genus found within the family Echinasteridae. The genera ''Henricia'' and ''Echinaster'' encompass 90% of all the species found within the family Echinasteridae. It contains 30 species, however the number of species in this genus is still debatable because of uncertainty within the genera. This genus is currently sub-divided into two sub-genera: ''Echinaster'' and ''Othilia'', evolutionary relationships between the sub-genera is not understood. ''Echinaster'' are found in the Pacific, Atlantic and Indian oceans, with most species being studied in the Gulf of Mexico and Brazil. The sub-genera ''Othilia'' is thought to encompass species mainly found in the Gulf of Mexico and Brazil. ''Echinaster'' is often one of the most studied species within the family Echinasteridae and is often used to find evolutionary relationships. Many species found within ''Echinaster'' are red, o ...

Echinaster Sepositus
''Echinaster sepositus'', the Mediterranean red sea star (sometimes only red sea star, but this name is also used for other species), is a species of starfish from the East Atlantic, including the Mediterranean Sea.Villamor, A.; and M. A. Becerro. (2010). ''Matching spatial distributions of the sea star Echinaster sepositus and crustose coralline algae in shallow rocky Mediterranean communities.'' Marine Biology 157: 2241-2251. Description ''Echinaster sepositus'' has five relatively slender arms around a small central disc. It usually has a diameter of up to , but can exceptionally reach up to .European Marine Life: Echinaster sepositus'' Retrieved 12 December 2015. It is a bright orange-red in colour, and has a soapy surface texture unlike superficially similar ''Henricia'' starfish (another somewhat similar species from the same region is '' Ophidiaster ophidianus''). The surface is dotted with evenly spaced pits from which the animal can extend its deep red gills ( papula). ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echinaster Heteractis
''Nepanthia belcheri'' is a species of starfish in the family Asterinidae. It is found in shallow water in Southeast Asia and northeastern Australia. It is an unusual species in that it can reproduce sexually or can split in two by fission to form two new individuals. As a result, it has varying numbers of arms, and Hubert Lyman Clark, writing in 1938, stated, "It is a literal truth that no two of the 56 specimens at hand, nearly all from Lord Howe Island, are exactly alike in number, size and form of arms". Description ''Nepanthia belcheri'' is a small starfish with broad arms with rounded tips. Small specimens tend to have five arms, while larger ones have six or seven, although the number of arms can range from one or two to 10. When 12 months old, the length of an arm is typically , after two years it is , in the third year it reaches and in the fourth . ''N. belcheri'' is a muddy brown colour. Distribution ''Nepanthia belcheri'' is native to the Pacific coast of Australia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Echinaster Spinulosus
''Echinaster spinulosus'', the small spine sea star, is a species of sea star found in shallow parts of the western Atlantic Ocean, the Caribbean Sea and Gulf of Mexico. Description ''Echinaster spinulosus'' is a medium sized sea star with five long tapering arms, round in cross section, attached to a central disc. Near one edge of this is the madreporite, a structure used for drawing in water to replenishing the water vascular system. The aboral or upper surface is covered in flat plates, each of which bears several short, blunt spines. These plates are quite prominent. They have fine granulations and are arranged in fifteen to twenty irregular rows that continue down the arms. On the margin of the arms are a row of plates with flattened spines and on the oral (under) surface, on either side of the ambulacral grooves, are larger plates, each bearing one small and two larger spines. In the grooves there are several rows of bright orange tube feet with suckers. The tips of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
