Heliaster Helianthus
The sun star ''(Heliaster helianthus)'' is a species of Asteroidea (starfish) in the family Heliasteridae. It is found in shallow water rocky habitats and in the kelp forests off the Pacific coast of Ecuador, Peru and Chile. Description ''H. helianthus'' is a multi-armed starfish, the number of arms usually being in the range 28 to 39, and the diameter typically being between . The aboral (upper) surface is brown with reddish tubercles while the oral (under) surface is white or yellowish-white. The disc is broad and the ossicles (plate-like components in the skin) in the proximal parts of the arms (closest to the disc) are connected to those of the neighbouring arms by connective tissue, forming inter-arm septa. This means that only a small part of each arm is free, the rest appearing to form part of the disc. Distribution and habitat This species is present in the southeastern Pacific Ocean, along the west coast of South America. Its range includes Ecuador, Peru and Chile, and ...

Forcipulatida
The Forcipulatida are an order of sea stars, containing three families and 49 genera Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclat .... Description Forcipulatids share with the brisingid sea stars distinctive pedicellariae, consisting of a short stalk with three skeletal Ossicle (echinoderm), ossicles. Unlike that group, however, the forcipulatids tend to have more robust bodies. The order includes some well-known species, such as the common starfish, ''Asterias rubens''. This order can be commonly found from Nor Carolina in the United States all the way to Santos in Brazil. Phylogeny The order is divided into three families: * Family Asteriidae — 39 genera * Family Heliasteridae — two genera * Family Zoroasteridae — eight genera World Register of Marine Species gives ...

Heliaster Kubiniji
''Heliaster kubiniji'' is a species of starfish in the order Forcipulatida. It is commonly known as the gulf sun star, the common sun star or estrella de mar de golfo and it occurs in the intertidal zone of the Pacific coast of California, Mexico and Nicaragua. Description Juvenile gulf sun stars that have recently undergone metamorphosis have five arms, but more arms grow as the animals get bigger and adults have nineteen to twenty five arms. Large individuals are a mauve colour with black and green blotching and banding while juveniles are a darker colour. It typically has a diameter of about . Distribution The gulf sun star is native to the eastern Pacific Ocean and its range extends from Cape Mendocino in California to Nicaragua. Biology The gulf sea star is a predator and feeds on anything edible it can find including barnacles, bivalve molluscs, gastropod molluscs, sea anemones, chitons, sea cucumbers and crabs.

Heliaster Solaris
''Heliaster solaris'' commonly known as 24-rayed sunstar is a possibly extinct sea star which was known from the waters near Española Island in the Galápagos Islands. Description ''Heliaster solaris'' had 22 to 24 cylindrical and elongated more or less distinctly banded rays which were tapering at the ends. They were one third longer than the diameter of the body. The dorsal rows of the spines were longer and more compressed. The spines, pedicellariae, and the madreporic plate were light yellowish. Taxonomy This species was first mentioned by John Edward Gray in 1840 in the Annals and Magazine of Natural History as ''Asterias multiradiata'' and later as ''Heliaster multiradiatus''. Due to the fact that Carl Linnaeus used the name ''Asterias multiradiata'' (current accepted name: '' Capillaster multiradiata'') already in 1758 Gray's name became an invalid homonym. In 1920 Austin Hobart Clark published the replacement name ''Heliaster solaris''. Extinction ''Heliaster solaris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Labidiaster Annulatus
''Labidiaster annulatus'', the Antarctic sun starfish or wolftrap starfish is a species of starfish in the family Heliasteridae. It is found in the cold waters around Antarctica and has a large number of slender, flexible rays. Description ''Labidiaster annulatus'' has a wide central disc and 40 to 45 long narrow rays and can reach a diameter of . The disc is slightly inflated and is raised above the base of the rays. The madreporite is large and near the edge of the disc. The aboral or upper surface is covered in a meshed network of small slightly overlapping plates. These are covered by a membrane with numerous raised projections called papulae, some small spines and a few large triangular pedicellariae, wrench-like organs that can grasp objects. The rays are crowded together where they join the disc and their aboral surface is similarly clad in overlapping scales in a quadrangular mesh pattern. There are also short spines and many papulae and a number of small pedicellariae. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
