The Diadematidae are a family of sea urchins. Their tests are either rigid or flexible and their spines are long and hollow.
Tube-dwelling anemones or ceriantharians look very similar to sea anemones but belong to an entirely different class 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. Within the tubes of these ceriantharians, more than one polyp is present, which is an exceptional trait because species that create tube systems usually contain only one polyp per tube. Ceriantharians were formerly classified in the taxon Ceriantipatharia along with the black corals but have since been moved to their own class, Ceriantharia.

Spongilla is a genus of freshwater sponges containing over 200 different species. Spongilla was first publicly recognized in 1696 by Leonard Plukenet and can be found in lakes, ponds and slow streams.Spongilla have a leuconoid body form with a skeleton composed of siliceous spicules. They are sessile organisms, attaching themselves to hard substrate like rocks, logs and sometimes to ground. Using their ostia and osculum these sponges filter the water for various small aquatic organisms such as protozoans, bacteria, and other free-floating pond life. Sponges of the genus Spongilla partake in symbiotic relationships with green algae, zoochlorellae. The symbiotic zoochlorellae give the sponges a green appearance and without them they would appear white.
Bithyniidae is a family of small freshwater snails with an operculum, aquatic gastropod molluscs in the clade Littorinimorpha.
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.
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.
