Radiospongilla is a genus of freshwater sponges in the family Spongillidae. It was defined by Penney and Racek in 1968. The type species is Radiospongilla sceptroides . [1]

A genus is a taxonomic rank used in the biological classification of living and fossil organisms, as well as viruses, in biology. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus.

Spongillidae family of freshwater demosponges

Spongilidae is a family of sponges that live in freshwater lakes and rivers. The following genera are recognized in the family:

Type species term used in zoological nomenclature (also non-officially in botanical nomenclature)

In zoological nomenclature, a type species is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen(s). A similar concept is used for suprageneric groups called a type genus.

Species

The following species are recognised in the family:

Radiospongilla sceptroides is a species of freshwater sponge in the family Spongillidae. It was described as Spongilla sceptroides by Scottish-born Australian zoologist William A. Haswell in 1883, who discovered it growing on submerged wood in a pond in the vicinity of Brisbane. He described it as "Sponge green, encrusting, smooth, moderately elastic, not crumbling." He noted the spicules were fusiform and pointed. It was found growing next to a yellowish freshwater sponge that he described as Spongilla botryoides. A 1968 review of freshwater sponges failed to locate Haswell's original type specimen, so a new one was selected from the Merrika River near Womboyn in New South Wales.

Whip-lash squid Family of cephalopods known as whip-lash squid

The Mastigoteuthidae, also known as whip-lash squid, are a family of small deep-sea squid. Approximately 20 known species in six genera are represented, with members found in both the mesopelagic and bathypelagic zone of most oceans. Originally described by Verill in 1881, it was later lowered by Chun (1920) to a subfamily (Mastigoteuthinae) of the Chiroteuthidae. However, Roper et al. (1969) raised it back to the family level, and this has not been changed since. The taxonomy of this family is extremely unstable, and there have been at times one genus, two genera and four subgenera(Salcedo-Vargas & Okutani, 1994), two genera and several 'groups', five genera and one species with an uncertain placement, or six genera.

Tube-dwelling anemone order of cnidarians

Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different subclass of anthozoans. They are solitary, living buried in soft sediments. Tube anemones live inside and can withdraw into tubes, which are composed of a fibrous material made from secreted mucus and threads of nematocyst-like organelles known as ptychocysts. Ceriantharians were formerly classified in the taxon Ceriantipatharia along with the black corals but have since been moved to their own subclass, Ceriantharia.

<i>Spongilla</i> genus of sponges

Spongilla is a genus of freshwater sponges in the family Spongillidae found in lakes and slow streams. Sponges of the genus Spongilla attach themselves to rocks and logs and filter the water for various small aquatic organisms such as protozoans, bacteria, and other free-floating pond life. Unlike marine sponges, freshwater sponges are exposed to far more adverse and variable environmental conditions, so they have developed gemmules as a means of dormancy. When exposed to excessively cold or otherwise harsh situations, the sponges form these gemmules, which are highly resistant "buds" that can live dormant after the mother sponge has died. When conditions improve, the gemmules "germinate" and a new sponge is born.

Arachnactidae family of cnidarians

Arachnactidae is a family of tube-dwelling anemones in the order Ceriantharia. It is the only family in the monotypic order Penicillaria and comprises around 38 species. They differ from other ceriantharians in the makeup of their cnidome, the relative sizes of the oral discs and the shape and structure of the mesenteries. These tube anemones dwell in parchment-like tubes immersed in soft sediment, and have two whorls of tentacles, the outer ones being much longer than the inner ones.

Poecilasmatidae is a family of goose barnacles.

Gonatopsis is a genus of squid from the family Gonatidae. They are characterised by the loss of their tentacles by the time they have reach the subadult stage. They have arms which have two series of hooks along the midline of the oral surface arms, the radula has five or seven teeth, the mantle can be muscular or flabby, fins are rhomboid or arrow shaped and they lack photophores. They are found in the North Pacific.
