Meridiastra Gunnii

	Meridiastra Gunnii ''Meridiastra gunnii'' is an Australian species of 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 .... It has six arms and can be any colour. Molecular evidence indicated that there were genetically divergent eastern and western forms of what is currently referred to as ''M. gunnii'' in southern Australia, and that a taxonomic revision was necessary. Further studies have shown that it can be conspecific with ''Patiriella brevispina''.P.M O'Loughlin et al., A molecular and morphological review of the asterinid, Patiriella gunnii (Gray) (Echinodermata: Asteroidea).

picture info	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 fe ...

	Museums Victoria Museums Victoria is an organisation that includes a number of museums and related bodies in Melbourne. These include Melbourne Museum, Immigration Museum, Scienceworks, IMAX Melbourne, a research institute, the UNESCO World Heritage-listed Royal Exhibition Building and a storage facility in Melbourne's City of Merri-bek. As the custodian of more than 15 million collection items, Museums Victoria traces the natural, social and cultural records of the Australasian region. Cultivated over nearly two centuries, this invaluable collection enables nationally and globally significant research. Their natural history collections are especially vital to scientists shaping conservation strategies through research, tracing the impacts of the world’s changing environment on biodiversity. Launched in 2022, Museums Victoria Research Institute addresses some of the biggest and most complex challenges of the era through a lens of change, drawing on multiple knowledge systems and perspectives ...

	Asterinidae The Asterinidae are a large family of sea stars in the order Valvatida. Description and characteristics These are generally small sea stars, flattened dorsally and bearing very short arms, often giving a pentagonal shape in the body ;example: ''Asterians rubens'' (except in some species possessing more than five arms). The periphery of the body is thin and formed by indistinct, tiny marginal plates. They are characterized by their aboral face formed by plates shaped like crescents, sometimes giving a "knitted" appearance to the skin. The abyssal species can be bigger, like those of the genus '' Anseropoda'', which can exceed 45 cm in diameter. Biology Most of the species are small and relatively cryptic: they are often found hidden under rocks or in crevices, for example. Several species have access to a fissiparous asexual reproduction, multiplying their reproductive potential. For that reason, some species of the genera '' Meridiastra'' and '' Aquilonastra'' can some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
