Iconaster is a genus of echinoderms belonging to the family Goniasteridae. [1]
The species of this genus are found in Australia and Malesia. [1]
Species: [1]
Starfish or sea stars are star-shaped echinoderms belonging to the class Asteroidea. Common usage frequently finds these names being also applied to 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, tropical zones to frigid, polar regions. They are found from the intertidal zone down to abyssal depths, at 6,000 m (20,000 ft) below the surface.
The Valvatida are an order of starfish in the class Asteroidea, which contains 695 species in 172 genera in 17 families.
The Asterinidae are a large family of sea stars in the order Valvatida.
Methanococcus is a genus of coccoid methanogens of the family Methanococcaceae. They are all mesophiles, except the thermophilic M. thermolithotrophicus and the hyperthermophilic M. jannaschii. The latter was discovered at the base of a “white smoker” chimney at 21°N on the East Pacific Rise and it was the first archaeal genome to be completely sequenced, revealing many novel and eukaryote-like elements.
Goniasteridae constitute the largest family of sea stars, included in the order Valvatida. They are mostly deep-dwelling species, but the family also include several colorful shallow tropical species.
Culcita is a genus of sea stars. They are found in tropical waters. Some are kept in home aquariums.
The Brisingids are deep-sea-dwelling starfish in the order Brisingida.
Elasipodida is an order of sea cucumbers. They have numerous appendages, including conical papillae and leaf-like tentacles. Although many species are benthic, a number are pelagic, and may have their appendages modified to form sails or fins. Most members of the order inhabit deep-sea environments, such as the species of the genus Enypniastes.
Cidaridae is a family of sea urchins in the order Cidaroida.
The Oreasteridae are a family of sea stars in the class Asteroidea.
Archasteridae is a family of starfish found in shallow waters in the tropical Indo-Pacific region. The genus Astropus, previously included in this family, is now included in the genus Archaster with the single species, Astropus longipes, being accepted as Archaster lorioli Sukarno & Jangoux, 1977.
Orthasterias is a genus of sea stars in the family Asteriidae. Orthasterias koehleri, the rainbow star or red-banded sea star, is the only species in the genus. It is found in the North Pacific Ocean.
Hippasteria is one of 70 genera of sea stars in the diverse family Goniasteridae.
Fromia is a genus of starfish belonging to the family Goniasteridae.
Iconaster longimanus, the icon star or double star, is a species of starfish in the family Goniasteridae. It is found in the west and central Indo-Pacific Ocean. The genus name comes from the Greek eikon, meaning portrait or image and possibly referring to the way the marginal plates frame the disc, and aster, meaning star. The specific name comes from the Latin longus manus and refers to the long, slender arms.
The Zoroasteridae are one of three families of Asteroidea in the order Forcipulatida. It contains seven living genera and one extinct genus.
The Echinothuriidae are a family of sea urchins in the order Echinothurioida. Due to their soft skeletons, most are called "leather urchins", but species in the genus Asthenosoma are also known as "fire urchins" due to their bright colors and painful, venomous sting.
Evoplosoma is a genus of deep-sea sea star in the family Goniasteridae.
Glyphodiscus is a genus of echinoderms belonging to the family Goniasteridae.
Kanakaster is a genus of echinoderms belonging to the family Goniasteridae.
