Rossellidae
Rossellidae is a family of glass sponges belonging to the order Lyssacinosa. The family has a cosmopolitan distribution and is found at a large range of depths (, and likely deeper). Description The body is usually a cup-like structure. In stalked forms the body can be mushroom-like. Spicules protruding beyond the sponge surface, when present, are diactines (spicules with two pointed arms) or specialised outwardly protruding hypodermal pentactines (five pointed spicules). The choanosomal skeleton consists of diactines, sometimes together with less frequent hexactines (spicules with six prongs). A large variety of microscleres occur in this family, including a variety of holactinoidal and asterous spicules. Subfamilies and genera , WoRMS recognizes three subfamilies and twenty-six genera in the family: * Subfamily Acanthascinae ** Acanthascus ** Rhabdocalyptus ** Staurocalyptus ''Staurocalyptus'' is a genus of sponge. It was circumscribed in 1897 by Isao Ijima. Tax ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rossella (sponge)
''Rosella'' is a genus of glass sponges in the family Rossellidae. It is found in the Antarctic and sub-Antarctic regions. Description Species are thick-walled saccular sponges. Calycocomes (six rayed spicules with secondary rays emanating from a solid calyx) are always present. They are often accompanied by spherical discohexactines (six rayed spicules with secondary rays ending as small discs), mesodiscohexasters (microscleres with primary rays that are rearranged by fusion to form eight compound primary rays situated at the corners of a cube. Secondary rays end as small discs) and microdiscohexasters (smaller forms of mesodiscohexasters). Dermalia (outer spicules of any size class) are usually pentactines, sometimes with stauractines (cross-like spicules with four perpendicular rays) and hexactines. Prostalia lateralia (large protruding spicules), when present, are monaxons (spicules with a single axis) and sometimes pentactines. The hypodermal pentactine spicules (spicu ...

Staurocalyptus
''Staurocalyptus'' is a genus of sponge. It was circumscribed in 1897 by Isao Ijima. Taxonomy Ijima circumscribed ''Staurocalyptus'' as a genus in the family Rossellidae. His initial taxonomy included three newly described species and two transferred from ''Rhabdocalyptus''. Ijimi did not designate a type species; in 1967 V. M. Koltun designated ''Rhabdocalyptus dowlingi'' as the type species. A 2002 revision of Rossellidae by K. R. Tabachnick demoted ''Staurocalyptus'' to be a subgenus of '' Acanthascus'' and designated a new type species: ''Staurocalyptus glaber'' . However, , WoRMS Worms may refer to: *Worm, an invertebrate animal with a tube-like body and no limbs Places *Worms, Germany Worms () is a city in Rhineland-Palatinate, Germany, situated on the Upper Rhine about south-southwest of Frankfurt am Main.

Rossella Antarctica
''Rossella antarctica'' is a relatively small species of glass sponge. It is widely distributed in the southern hemisphere, particularly in the Antarctic and sub-Antarctic regions. Description This off-white to grey sponge may grow up to long. It has a semispherical to ovoid form with a large, deep oscule on the upper surface. The upper part also has the largest diameter of the organism. The body is dense and contains relatively few canals. The whole surface is covered with long, hair like spicules that may protrude up to from the surface. These spicules are most dense at the base, where they entangle to form a stalk that attaches the sponge to the substrate.Uriz, María Jesús (1988).
